The hemp plant (Cannabis sativa) — the primary source of CBD

What is Cannabidiol?

Cannabidiol is just one of the 421 chemicals contained in the cannabis plant [1]. It’s the primary medicinal component in the leaves and flowers.

CBD owes most of its health benefits to its ability to interact with the endocannabinoid system. The main role of this system is to support homeostasis (balance) throughout the body (more on this later).

There are over 117 different cannabinoids in the cannabis plant — each one offering a unique effect on the body.

The most abundant cannabinoid in the plant is usually CBD, followed by the main psychoactive component — THC (tetrahydrocannabinol). Other cannabinoids like CBC (cannabichromene), CBG (cannabigerol), and CBN (cannabinol) make up the bulk of the remaining cannabinoid profile.

What Are the Benefits of CBD?

CBD has many reported benefits — from easing pain and inflammation all the way to protecting the brain from neurodegenerative disorders.

A lot of the benefits of CBD oil and other CBD products are a result of the effects this compound has towards homeostasis (balance).

The main benefits of CBD include:

What Are the Side Effects of CBD?

Just like any health supplement, there are some side effects of CBD.

While these side effects are generally very mild in nature, it’s possible for more severe side effects to occur as well — especially if used in combination with other supplements, medications, or underlying health conditions.

It’s important to always speak with your doctor about using CBD if you have any underlying health problems.

Side Effects of CBD May Include:

  1. Low blood pressure (defined as blood pressure below 110/80 mm Hg)
  2. Dry mouth (Xerostomia)
  3. Fatigue
  4. Diarrhea
  5. Poor appetite
  6. Nausea and vomiting
  7. Skin rash

What to Expect When Taking CBD For the First Time

Depending on your symptoms, you may find relief immediately after taking CBD — while other times you’ll need to be patient and keep taking the CBD supplements for a few days, weeks, or even months before you start to notice any signs of improvement.

It’s important to keep a realistic expectation when using any medication or supplement for a particular symptom or medical condition.

Think of it like this — if your symptoms took a long time to develop, they would likely require a long time to leave again as well.

Conversely, if your symptoms came on quickly, they also tend to leave quickly.

What’s The Dose of CBD?

One of the most confusing aspects of starting CBD for the first time is figuring out the right dose to take.

Finding the best dosage for CBD products is confusing because it can be different from one person to the next.

There Are a Few Factors That Can Make the Effective Dose of CBD Different:

  1. Genetic variability in the liver can affect CBD metabolism
  2. Some symptoms require different doses to produce results
  3. Reduced gut health can mean less CBD is absorbed into the bloodstream
  4. Other ingredients in the CBD product can enhance or reduce absorption
  5. Some people are much more sensitive to CBD than others

All these factors can compound together to make dosing very challenging for new users — but it doesn’t need to be this way.

The easiest way to find the right dose is to use our chart below to identify the ballpark estimate of what dose. From here you can spend a few days playing with this dose to dial it in for your body individually.

Estimated Doses of CBD by Weight & Strength (in mg CBD):

WeightLow StrengthMedium StrengthHigh Strength
100 lbs (45 kg)10 mg30 mg60 mg
125 lbs (57 kg)13 mg38 mg75 mg
150 lbs (68 kg)15 mg45 mg90 mg
175 lbs (80 kg)17 mg52 mg105 mg
200 lbs (90 kg)20 mg60 mg120 mg
225 lbs (102 kg)22 mg67 mg135 mg
250 lbs (114 kg)25 mg75 mg150 mg

Once you know the dose you should be taking per day; you can choose to separate it into two or three separate doses. You need to determine how much of the CBD product you have you will need to take to achieve this dose.

Capsules and gummies are easy because they usually tell you exactly how much CBD each piece has.

Oils are slightly harder to gage as you first need to determine how much CBD per mL the oil has before calculating the amount you need to take to hit that dose.

What Type of CBD Products Should I Use?

There are so many different forms of CBD on the market it can be difficult to decide which one to spend your money on.

Here are a few examples and when you should consider using each of them:

A) CBD Oils & Tinctures

Oils are the most common form of CBD products. They have several advantages over other methods of CBD product types:

  • They’re cost-effective
  • They have a long shelf-life
  • Doses can be accurately dialed in
  • They can be mixed with other ingredients to further optimize for the intended use

CBD oil can be used for virtually any condition CBD may is indicated for — including skin conditions.

If you’re not sure where to begin, CBD oils are a safe place to start.

Depending on what you’re using CBD for, it’s better to find something in the middle to high-potency range. These oils are going to have the most versatility. You can take high doses or dilute them down to lower doses if needed.

Most people can hit an accurate dose with a high potency oil even if they take relatively small doses.

Higher potency oils are almost always the most cost-effective option as well — averaging about $0.09 per mg of CBD. This compares to low potency oils that tend to average closer to about $0.14 per mg of CBD.

B) CBD Topicals

Topical CBD products are great for anything involving the skin, muscles, or joints. It delivers the CBD and other ingredients directly to the site.

Most CBD topicals on the market don’t have a high enough CBD concentration to be of any real value for treating more severe symptoms — however, they may still be useful for mild symptoms or in general skincare.

The best topical CBD products will have have a potency of at least 10 mg/mL CBD and will include other beneficial ingredients like other herbal extracts as well.

C) CBD Capsules

CBD capsules can be used for the same applications as CBD oils and tinctures.

The difference is that capsules come in pre-measured doses of CBD — so there’s no need to measure out your daily dose.

The tradeoff is that you have less control over the dose you’re getting with capsules, and they tend to be slightly more expensive than equivalent oils.

CBD capsules are great for anybody looking to make their CBD supplementation as simple as possible. You can find CBD capsules in multiple different potencies depending on your size and intended use.

D) CBD Suppositories

The CBD will be absorbed into the bloodstream through capillaries in the rectum. Most people would understandably prefer the other CBD options as they’re less invasive.

Where suppositories truly shine is with lower digestive discomfort. Conditions including inflammatory bowel disease, irritable bowel syndrome, and various other digestive tract disorders may have a lot to benefit by introducing CBD directly to the source of the issue.

CBD suppositories are a specialized product and will tend to be higher pricing than average compared to other CBD products.

E) CBD Vape Oils & Vape Pens

Vape pens and vape oils (e-liquids) are a popular way of taking CBD.

They’re convenient, highly portable, and provide fast-acting results. You can find all shapes and sizes of vape oils and pens, in almost every flavor imaginable. You can also find options that create vape clouds, and others that don’t if you’d prefer to be more discrete.

Vape oils and pens are great for people who need all-day relief or simply enjoy vaping as a way of taking their daily doses of CBD.

The downside of vaping is that it’s still too new to know the extent of the long-term negative health effects of the practice.

F) CBD Gummies

CBD isolates can be added to edibles to make a more enjoyable CBD supplement. They’re often added to cooking oils or butter and can be added to gummy candies as well. This is very popular as they taste great and work much like a CBD capsule.

CBD gummies and other forms of CBD edibles are excellent products for those taking CBD casually for mild to moderate symptoms — but shouldn’t be relied on for larger doses. Large doses of CBD from gummies also means large doses of sugar (which isn’t going to do us any favors towards our health).

G) CBD Concentrates

A CBD concentrate is a purified extract of either CBD isolate or full-spectrum extracts.

CBD isolates are pure (isolated) CBD and generally come in the form of a white crystalline powder. This form of CBD concentrate is referred to as CBD crystals.

Full-spectrum extracts contain other cannabinoids, terpenes, and other phytochemicals — giving it more of a waxy, resinous appearance instead. This form of CBD concentrate is referred to as CBD waxes or dabs.

Most CBD oils, capsules, and gummies are made from a CBD concentrate that’s been diluted into a carrier medium for easy dosing. Concentrates can, therefore, be used in the same way as these other products, but require more care and attention to avoid taking too strong a dose.

CBD concentrates are a great option for people who need a larger dose of CBD to find relief from their symptoms. They’re also a good option for people looking to make their own CBD topicals, capsules, gummies, or oils.

Is Hemp the Same as Marijuana?

One of the most confusing aspects of cannabis-based products is the difference between hemp and marijuana. This is an important distinction to make when considering the legality and therapeutic effects of a CBD extract.

Both of these plants are the same species (Cannabis sativa) — yet their growth habits are radically different.

The easiest way to understand the difference between marijuana and hemp is to compare it to different types of dogs.

Let me explain…

All dogs are the same species — Canis lupus familiaris — despite there being hundreds of clearly different types of dogs. A chihuahua and a Doberman are both the same species of dog  — despite having an incredible amount of physical differences between the two  (size, shape, and habits/instincts).

Just like dogs, hemp and marijuana are different enough to warrant individual names and uses, but similar enough that they can still breed together and produce offspring.

The biggest difference in growth habits between the two is that hemp doesn’t produce THC in any meaningful supply. Instead, hemp focuses its attention on producing other cannabinoids, like CBD and CBC.

Marijuana, on the other hand, has been selectively bred for its THC content. These plants will produce high concentrations of both THC and CBD as well as any of the other cannabinoids the cannabis plant is capable of manufacturing.

Cannabinoid Profile Comparison of Hemp & Marijuana

(These cannabinoid profiles are just examples — these values can vary significantly from one strain to the next).

Therefore, CBD oils made from marijuana may contain THC, while CBD oils made from hemp don’t contain any psychoactive doses of THC.

In the United States, and throughout most of the world, hemp is considered legal due to its inability to produce THC (and therefore psychoactive effects), while marijuana is restricted or illegal for its intoxicating side-effects.

Depending on which country you’re living in, these laws can vary significantly. Always check your local laws before buying any hemp or marijuana oils to avoid legal troubles.

The Effects of CBD & Other Hemp-Derived Cannabinoids

There are at least 66 separate cannabinoids in the cannabis plant. Each one has a similar chemical structure and the ability to interact with the endocannabinoid system.

With so many cannabinoids in the plant, it’s useful to use a shortened naming system.

Common Cannabinoids and Their Abbreviations:

  • Cannabidiol — CBD
  • Cannabichromene — CBC
  • Cannabigerol — CBG
  • Cannabinol — CBN
  • Tetrahydrocannabinol — THC
  • Tetrahydrocannabivarin — THCV

Now let’s compare the similarities and differences between CBD and some of the other prominent cannabinoids.

1. CBD vs. THC

Although structurally the two are very similar, these two cannabinoids have very different effects on the body.

As we’ve mentioned, THC is the main reason marijuana offers psychoactive effects when smoked.

While CBD works to prevent the breakdown of naturally occurring endocannabinoids like anandamide, THC directly activates the endocannabinoid receptors.

One of the side-effects of this effect is the release of serotonin in the brain — which produces euphoric and mind-altering effects. Interestingly, the active ingredients in magic mushrooms and LSD (acid) also owe their hallucinogenic effects to their interaction with serotonin in the brain.

THC is mildly stimulating, which can be useful for conditions involving fatigue or low motivation — however, these same effects can make THC a problem for people with conditions like anxiety, insomnia, or schizophrenia.

THC is also undesirable for those looking to receive the health benefits of cannabis without the intoxicating side-effects.

Most CBD products on the market have little to no THC content to prevent these intoxicating effects. Always check the label to make sure this is the case before making your purchase.

2. CBD vs. CBC

CBC stands for cannabichromene. It’s the third most abundant cannabinoid in the cannabis plant. Like CBD, CBC is non-psychoactive and has a relaxant effect on the central nervous system.

Some preliminary research even suggests that CBC is as useful, if not more useful for treating anxiety than CBD. More research is needed to confirm this, however.

3. CBD vs. CBG

CBG stands for cannabigerol — it’s the precursor molecule for THC, CBD, and CBC among other lesser cannabinoids.

The cannabis plant produces CBG before it moves through other stages to become other cannabinoids depending on the plant’s genetics and growing environment.

Plants harvested early are more likely to have high CBG content.

CBG has been shown to block the effects of THC on serotonin [2] and can, therefore, reduce many of the common side-effects of THC including euphoria, anxiety, and paranoia.

More research is needed to fully understand the medical value of CBG — at the moment, there isn’t much focus on this cannabinoid.

4. CBD vs. CBN

CBN (cannabinol) is the opposite of CBG — it’s produced as CBD and THC degrade into smaller compounds.

Hemp plants that are harvested late will be higher in CBN. Additionally, cannabis that has been stored improperly (too dry, or too long) will also be higher in CBN.

This cannabinoid is mildly psychoactive in sensitive individuals. Its primary effects are to provide a heavy, sedating sensation — making it especially useful for treating insomnia, stress, OCD, or anxiety.

We’re starting to see a few CBD products hitting the market that contains CBN as a way to boost the sedative effects of the cannabinoid overall.

Full-Spectrum vs. CBD Isolates

There are three main philosophies when it comes to deciding what cannabinoid profiles a company should use in their products — full-spectrum, CBD isolate, and broad-spectrum CBD oils.

A) Full-Spectrum Extracts

As the name implies, a full-spectrum extract contains all the cannabinoids naturally found in the cannabis plant. There will be large amounts of CBD with smaller concentrations of CBC, CBG, CBN, and other cannabinoids.

Full-spectrum extracts are a more direct representation of the cannabis plant as a whole.

Along with all the various cannabinoids in the plant, full-spectrum extracts will also provide the terpenes, lignins, polyphenols, and various other phytochemicals found in the cannabis plant — which have medicinal effects of their own.

Generally speaking, a full-spectrum extract is considered more potent than isolates. This is due to a concept commonly known as “the entourage effect.”

(Example lab test for a full-spectrum extract — notice how many different cannabinoids register on the test)

B) CBD Isolates

CBD isolates are manufactured by adding another purification step to the process.

Once the phytochemicals are extracted from the leaves and flowers of the plant, an extra process called chromatography is used to separate the CBD from the rest of the chemicals.

This results in a pure CBD extract — free from all the other phytochemicals.

CBD isolates will form a white crystalline substance. Products made with CBD isolates tend to be cheaper than full-spectrum. This is because despite having extra steps involved with manufacturing, it allows companies to use low quality hemp to make the extract since most of the other constituents and potential contaminants will be removed during the isolation process anyway.

Isolates tend to require higher doses than full-spectrum extracts to produce the same results. They lack the additional therapeutic benefits of the other cannabinoids and terpenes in the cannabis plant.

(Example lab test for an isolate-based extract — notice how only CBD appears on the test)

C) Broad-Spectrum Hemp Extracts

There is also a third type of CBD extract not commonly discussed — called broad-spectrum extracts. Some companies are calling this “controlled-spectrum” extracts.

They’re made by first separating the cannabinoids and terpenes into their individual components before recombining them in specific ratios. They mimic a full-spectrum extract but aren’t nearly as diverse.

These extracts will look a lot like a full-spectrum extract on a lab test but are synthetically formulated from various isolates (CBD isolate, CBC isolate, CBG isolate, etc.).

Broad-spectrum extracts can vary a lot in their effects depending on the cannabinoid ratios. Many manufacturers will also add terpenes to the final product.

(Example lab test for a broad-spectrum extract — notice how some cannabinoids appear while others don’t)

The Nitty Gritty: How Does CBD Actually Work?

CBD is a potent medicinal compound shown to provide symptomatic support for a long list of medical conditions and symptoms including epilepsy, anxiety, chronic pain, nausea, insomnia, stress, multiple sclerosis, neurodegenerative disorders, and endocrine disorders.

How can one simple compound have such a diverse list of medical benefits?

As mentioned previously, the answer lies in CBD’s ability to interact with a system in the body that’s involved with homeostasis — the ECS.

This means that CBD regulates a system designed to keep us in balance, turning processes down when they become overactive, and turning them up when they are deficient.

This is very different from other medications or supplements — which usually have a specific direction of effects, either increasing or decreasing a given process in the body.

Let’s explore how CBD works in more detail:

1. CBD Boosts Endocannabinoid Levels (FAAH Inhibitor)

CBD inhibits an enzyme known as FAAH (fatty acid amide hydrolase). This enzyme is responsible for breaking down endocannabinoids inside the cells.

CBD inhibits FAAH, providing a boost in our naturally occurring endocannabinoids 2-AG and anandamide [3].

This is the main mechanism CBD uses to provide support on homeostasis. It’s the reason why CBD is thought to provide a “balancing effect” rather than forcing a reaction in the body in one direction or another.

2. CBD Activates the Vanilloid Pain Receptors

When you activate the vanilloid pain receptors, the result is a blockage of pain signals to the brain.

The vanilloid receptors have many responsibilities in the human body including regulating pain transmission, inflammation, and body temperature. There are several other herbs that interact with these receptors to produce medicinal effects, including ginger, black pepper, and chili peppers [14] — all of which are well known for their analgesic effects.

CBD activates the TRPV1 vanilloid receptors directly — reducing the intensity of pain signals being sent to the brain and broadly lowering inflammation throughout the body [4].

3. CBD Increases GABA Activity

GABA (gamma-aminobutyric acid) is our primary relaxing neurotransmitter. It acts like the brake pedal on the nervous system. When we start moving too fast (mentally overstimulated), GABA steps in to slow us down.

GABA is important for sleep hygiene because it prepares the mind to fall asleep at night.

This neurotransmitter is also necessary immediately following stress. It’s what reverses the process, slowing our heart rate, lowering blood pressure, and allowing us to relax and recover.

When GABA isn’t working properly, we may become anxious and find it difficult to turn off the stress response or fall asleep — resulting in anxiety, and insomnia.

GABA dysfunction can indirectly lead to lowered immunity, as well as digestive problems if the issue persists for long periods.

CBD is an allosteric modulator of GABA. This is a fancy term that means CBD doesn’t activate the GABA receptor directly — rather, it makes it easier for naturally occurring GABA to bind to the receptors itself [5].

The result is an increased feeling of relaxation, and lowered symptoms of hyperstimulation in the brain (anxiety, insomnia, PTSD, etc.).

This is also how a lot of prescription anti-anxiety medications work — such as benzodiazepines (i.e., Xanax, Valium, or Klonopin).

Unlike benzodiazepines, however, CBD is not addictive. There are no withdrawal symptoms when you stop taking CBD, even after many years of regular use.

CBD in the Medical Research — Evidence-Based Benefits of CBD

There are claims that CBD can cure just about everything these days — which obviously isn’t true. CBD is not a miracle cure and has limitations in what it can effectively treat.

Differentiating between exaggerated claims and reasonable recommendations for CBD can be difficult — especially with the limited amount of research available.

Keep in mind that CBD was virtually unknown to mainstream science 20 years ago, and research is a slow-moving process. It can take upwards of 10 years for the research to catch up to public health trends.

Here are some of the medical uses of cannabis that have the most evidence behind them.

1. CBD & Inflammation

CBD is a powerful anti-inflammatory compound [15] — in fact, its anti-inflammatory effects could be argued as a reason why CBD is so effective for other health conditions as well.

Chronic (long-term) inflammation is associated with many different medical conditions, including inflammatory bowel disease, Parkinson’s disease, Alzheimer’s disease, depression, arthritis, kidney disease, multiple sclerosis, and much more.

CBD targets the inflammatory process at multiple levels. It’s been shown to inhibit a host of inflammatory markers that work together to drive inflammation in the body.

This broad anti-inflammatory effect makes CBD useful for a host of symptoms related to inflammation, as well as protective effects on long-term health conditions including fatty liver disease, atherosclerosis, kidney disease, and inflammatory bowel disease.

2. CBD & Anxiety

Anxiety has many potential causes — nutritional deficiencies, traumatic events, chronic stress, medication side-effects, drug addiction, sleep deprivation, or metabolic disorders, for example. This diversity in potential causes can make treating anxiety difficult.

CBD provides some unique benefits towards treating anxiety, through its ability to enhance GABA activity, support sleep quality, reduce muscle tension, and improve symptoms related to gut health and inflammation that can indirectly lead to anxiety symptoms.

A clinical trial published in 2011 investigated the effects of CBD versus placebo on social anxiety disorder in a model involving public speaking as the source of anxiety [16]. Twenty-four participants with a social anxiety disorder were asked to speak in front of a camera. Baseline anxiety scores were taken before the event, as well as afterward.

The study found that those in the treatment group (taking CBD) experienced a rapid reduction in anxiety scores both before and after the public speaking event when compared to placebo control.

A phase 3 randomized clinical trial is also currently underway exploring the effects of a CBD oil capsule on patients with various forms of anxiety and panic disorders. This study is significantly larger and will likely become a key piece of evidence for the use of CBD on anxiety when it comes to an end.

3. CBD & Epilepsy

There’s a lot of research on the use of CBD for epilepsy — with several large clinical trials already published on the topic. Epilepsy is also the focus for an upcoming CBD and THC-based pharmaceutical antiepileptic drug known as Sativex [8], as well as similar medications like Epidiolex.

A 2016 cohort study, involving 74 patients with treatment-resistant epilepsy, gave participants a CBD-enriched hemp oil (20:1 CBD: THC ratio) for an average of 6 months. 89% of the participants in this study reported a reduction in the number of seizures they experienced [7].

Additionally, researchers noted other improvements in the patients’ behaviors, including increased alertness, communication, motor skills, and sleep quality.

4. CBD & Pain

Pain is another area with plenty of research to back up the claims made for the uses of CBD. There are a few qualities of the compound that make it an attractive option for pain management over other alternatives:

  1. CBD is not physically addictive
  2. CBD is effective in different types of pain
  3. CBD offers pain reduction through several unique mechanisms

A recent review article by Ethan Russo — a medical cannabis researcher — presented a series of randomized clinical trials involving pharmaceutical preparations of CBD and THC extracts (Nabilone, Sativex, and Marinol) and their effect on various types of pain [9].

The studies listed in the review show that CBD and THC can be used to alleviate different forms of pain, including:

5. CBD & Multiple Sclerosis

One of the leading pharmaceutical cannabinoid preparations (Sativex) was approved for use as a treatment for multiple sclerosis by the FDA in 2018. It was shown to improve common side-effects of MS including muscle spasms [10], bladder dysfunction [11], and nerve pain [12].

CBD, in particular, has been shown to provide some preventative effects on MS — characterized as an autoimmune disease involving the destruction of myelin on the nerves by T-cells. CBD inhibits problematic T-cells from migrating towards the microglia of the brain where it would normally trigger inflammation and degeneration of myelin [13].

When to Avoid CBD

CBD isn’t for everyone — here are some of the most important times when someone should avoid using CBD.

A) With Severe Depression

CBD is often suggested as a treatment for depression. While there is strong merit for this with mild to moderate depression — it may not be suitable for those with severe chronic depression.

A large meta-review analyzed 57 separate studies involving cannabis and depression to identify whether or not regular cannabis use was associated with depression. The study concluded that long-term cannabis use increased the risk of depression [6].

Anybody suffering from severe depression should refrain from using CBD or other cannabis products without supervision by a licensed medical professional.

B) Alongside Benzodiazepine Medications

Benzodiazepine medications are used to treat anxiety and insomnia symptoms. They work by enhancing the effects of the neurotransmitter GABA — which is one of the ways CBD offers its anti-anxiety and sedative effects.

Drugs like Xanax and Valium are significantly more potent than CBD at doing this. However, they can result in serious side-effects or potential for addiction if combined with other drugs or supplements that work through GABA.

Therefore it’s highly recommended that you avoid using marijuana or any CBD products alongside prescription benzodiazepine use.

C) In Places Where CBD is Illegal

Unfortunately, CBD is still considered illegal in some countries.

These laws are changing all the time, so you should look into your country, state, or province individually to keep yourself up to date on the laws of the place you’re living.

We don’t recommend using CBD in places where the compound is illegal.

Here are some alternatives you can explore if you check this box:

  • Kava (Piper methysticum) — for anxiety, pain, and insomnia
  • Kratom (Mitragyna speciosa) — for pain, stress, and anxiety
  • Turmeric (Curcuma longa) — for pain and inflammation
  • Frankincense (Boswellia serrata) — for pain, inflammation, and arthritis
  • Ginkgo (Ginkgo biloba) — for neurodegeneration and heart disease/atherosclerosis
  • Bacopa (Bacopa monieri) — for neurodegeneration, neurological disorders

What is the Endocannabinoid System (ECS)?

All animals have an endocannabinoid system (ECS). We even have specialized messenger molecules designed to work with the ECS, known as the endocannabinoids

The compounds in cannabis — the phytocannabinoids — are just the right shape that they can interact with the ECS.  

The ECS consists of a series of specialized receptors that control intracellular activities (activities happening inside the cell). This system is primarily involved with maintaining homeostasis (balance throughout the body), as well as protecting organs from chronic damage caused by exposure to toxic substances or inflammation.

Homeostasis refers to the ability of an organism to maintain a consistent, well-balanced internal environment.

Everything from body temperature to blood pH needs to be kept within a tight window of control for us to remain healthy.

You may be wondering how the ECS helps us maintain homeostasis. The answer isn’t that simple, unfortunately. This system uses a series of highly complex cellular feedback mechanisms to maintain balance — turning processes up when they’re too low, and dialing them down when they’re too high.

The best way to think of how this system works is by looking at the ECS like the “read receipts” on a text message.

Let me explain.

You’re sending a text message — telling them something important, like where to meet you after work. When someone opens your message to read it, you’ll receive a notification to tell you the message was received and read. This lets you know that you don’t need to resend the same message again.

The endocannabinoid system works like the read receipts for the body. It’s designed to improve the body’s ability to communicate with itself to keep tighter control over homeostasis.

Whenever a message is sent from one cell to another, the endocannabinoid system sends a message back to the sender to tell it that the message has been received and the requests will be taken care of.

Where is the ECS?

The endocannabinoid system is found throughout the body.

Endocannabinoid receptors are found on virtually every organ (to some degree) but are most abundant in the central nervous system (brain and spinal cord) and immune systems.

In these systems, the endocannabinoid receptors play a pivotal role in the regulation of our nervous system — which is why CBD is so useful for conditions like anxiety and epilepsy. It’s also an exceptionally important component of the immune system — making CBD useful for reducing inflammation and supporting autoimmune disorders like multiple sclerosis or ALS.

The body uses two main hormone-like compounds to regulate this system — known as the endocannabinoids.

The first one is an eicosanoid compound known as anandamide, which is most similar to CBD and acts as a general regulator for this system.

The other primary endocannabinoid is 2-AG — which is more similar in its effects to THC — working as a direct activator for the endocannabinoid receptors (CB1).

There Are Two Types of Endocannabinoid Receptors:

1. CB1 Receptors

The CB1 receptors are most abundant in the central nervous system of the spinal cord and brain. These receptors are used to control neurotransmitters including dopamine, serotonin, and norepinephrine. Through these effects, the CB1 receptors play a role in the regulation of mood, sexual function, memory formation and retrieval, and overall cognitive health.

Most of the psychoactive effects of THC are due to an activation of the CB1 receptors in the spinal cord and brain, triggering a release of serotonin.

2. CB2 Receptors

The CB2 receptors are found throughout the peripheral tissues including the skin,  muscles, and the immune cells. They’re used to regulate the release of cytokines — tiny messenger molecules used to send messages around the body to other immune cells.

Through its effect on the immune cells, CB2 receptors are used to boost immune function during infection and cancer and are involved with the process of inflammation, and autophagy (garbage disposal of damaged or infected cells around the body).

Summary: What is CBD?

CBD is a fairly new health supplement with a lot to offer for certain medical conditions or symptoms.

It’s a lot more complex than many other health supplements — due to the complexity of the endocannabinoid system it works through. This system is involved with keeping the organs throughout the body in balance (homeostasis). This gives CBD a bidirectional effect and makes it very hard for researchers to quantify.

Nevertheless, there are many uses for this supplement — the most difficult part is choosing which products to buy and how much to take.

Using our guidelines above, you can dramatically reduce the time it takes to find the right dose. Additionally, you can save your money by reading through our company and product reviews to avoid buying low-quality CBD products. It’s also important to manage expectations when taking CBD — some symptoms may clear up immediately as the CBD begins to kick in, others can take a few weeks, or even months of regular use before benefits start to appear.

Be patient and persistent when taking CBD — and always consult with your doctor whenever using CBD or any other health supplement for a specific condition — especially if taking other medications at the same time.
