Antibiotic resistance is a serious problem in the modern world. CBD may be able to help by blocking the ability for bacteria to withstand their effects.
Antibiotic resistance is a major threat to public health.
The common drug-resistant bacteria MRSA (methicillin-resistant Staphylococcus aureus) is responsible for more deaths per year than HIV .
Every year, more and more strains of infectious bacteria become resistant to our medicine. On top of this, in the past 30 years, only 1 new class of antibiotic has been developed.
At these current rates, we won’t be able to defend ourselves against infectious disease for much longer.
Cannabis, as the wildcard it is, offers a unique solution to this problem.
Many of the cannabinoids in the plant prevent the ability of bacteria to resist the drugs we use to kill them.
Here, we discuss how cannabis is effective for preventing drug resistance and what the limitations are.
We’ll get into the details of drug resistance and how CBD oil can be used to prevent it later on.
For now, let’s just gain some context as to how this works.
A number of studies on several cannabinoids have shown that they can interrupt a bacteria’s ability to resist antibiotic treatment.
Most of these studies are focused on a strain of drug-resistant bacteria that infects the skin, known as Methicillin-Resistant Staphylococcus aureus (MRSA).
Finding a high-quality CBD oil containing the entire array of phytochemicals in the hemp plant is going to be the best option for drug-resistance. These oils are often referred to as “full-spectrum” extracts.
You can apply these oils directly to the skin along with your prescribed antibiotics.
Research is still being done to determine the potency of these oils when taken orally and the dosage needed for them to work.
Over the past 80 years, bacterial infection is relatively low on the list of concerns for doctors and patients alike.
This is because since the early 1930s we’ve had effective antibiotics for treating these infections.
Prior to this, bacterial infection was a common cause of death. In fact, people born before the 1930s had an average life expectancy of about 47 years .
Infectious diseases such as smallpox, cholera, diphtheria, pneumonia, typhoid fever, tuberculosis, and syphilis were both common and deadly.
We lacked effective treatments for these infections—a mere papercut could result in death to those who were unlucky enough to contract a dangerous bug.
Antibiotics changed everything.
In 1928, a Scottish microbiologist named Alexander Fleming accidentally discovered a mold species known as Penicillium notatum growing in a petri dish.
What was peculiar about this mold was that it was killing the bacteria around it.
Over the next decade, Fleming developed this into the medicine we now know as penicillin.
This forever changed the way we perform medicine.
Since the invention of penicillin, we no longer had to worry about bacterial infection. We had the treatment that could kill virtually any invading bacteria we contracted.
Three years before antibiotics were even released to the public, the scientists developing them already started seeing signs of resistance. However, the real problem started when a strain of Staphylococcus became resistant to penicillin in 1940.
Subsequently, the following bacterias mutated: tetracycline-resistant Shigella in 1959, methicillin-resistant Staphylococcus in 1962, penicillin-resistant Pneumococcus in 1965, and erythromycin-resistant Staphylococcus in 1968.
Over the next 50 years, drug resistance skyrocketed. We now have resistant strains popping up every single year.
A report published by the CDC in 2016 highlighted how serious this issue actually is.
At least 2 million people become infected with antibiotic-resistant bacteria each year and more than 23,000 people die annually as a consequence of these infections.
As more of these bugs become resistant to medication, this number is sure to rise substantially.
In the past couple of years, a new strain of the bacteria responsible for typhoid fever has emerged around Pakistan, showing resistance to all but one antibiotic.
As soon as it develops resistance to our last remaining option, there will be nothing available to treat it.
So how does drug resistance work? And how can CBD oil prevent it?
Let me explain with an overview of how antibiotics kill bacteria.
There are many different kinds of antibiotics, but the majority of them works in the same way:
Antibiotics prevent bacteria from growing.
If the bacteria can’t grow or multiply, they won’t have the potential for much damage.
Bacteria wreak havoc in numbers. A single bacteria, or even a few hundred, will have little effect on the body.
When we start to get a few hundred thousand or a few million, however, these organisms can cause serious damage.
Antibiotics work by blocking specific parts of the bacteria needed for growth.
For better understanding, let’s compare these mechanisms to a construction site. The construction site is the bacteria, working on building new bacteria to infect new areas of the body.
A few common examples of antibiotics include:
These block the bacteria’s ability to build their cell wall. When this happens, the cells begin to tear apart as they grow, causing the insides to leak out. This, of course, is fatal for the bacteria.
It’s like opening the gates to a construction site and letting all the workers leave, taking their tools with them. When nobody is left to do the work, the site is eventually abandoned.
Macrolides stop cell growth by attacking the RNA. This is the part of the cell responsible for building new proteins.
No proteins mean no growth. Since proteins are responsible for everything a bacteria does, it essentially disables them. They float around aimlessly before eventually dying.
This is like destroying the machinery on a job site. Nobody will be able to do any work, and the job will eventually be abandoned altogether.
Quinolones attack the DNA of bacteria directly.
DNA gives all directions and instructions on how the cell is supposed to work. If these are broken, the cell is unable to build anything and will quickly die as a result.
It’s like going into a construction site, completely destroying the blueprints and dismissing the master builder. The workers will try to keep going, but don’t know how to do their jobs effectively. The building will likely fall apart before it’s ever finished.
The lifespan of bacteria is very short.
But even so, like all organisms on earth, they are subjected to natural selection and evolutionary changes. Eventually, this evolution will lead to bacteria that are adapted to resist antibiotics.
Let me explain.
Every time a bacteria is made, there is a small chance its DNA will suffer a mutation somewhere. Most of the time this change does nothing. It is neutral.
But occasionally, this mutation has an effect. It can make the bacteria either stronger or weaker.
How? Natural selection. The stronger bacteria have a better chance of surviving, passing on its strong genes into the next generation. Meanwhile, the weaker bacteria are in a disadvantage, dying out and taking its “weak” genes out of the genetic pool.
Through random trial and error, and over the course of many generations, these mutations will eventually make that bacteria population more successful at doing its job. A bacteria’s job, like all life on earth, is to stay alive long enough to reproduce.
Let’s say we have 100 bacterial cells. Each one is the same but has one subtle mutation in its genetic code.
We then soak these bacteria in antibiotics.
The vast majority of these bacteria will die off. However, by chance, one of them manages to survive. Its unique, random mutation protected it from the antibiotics. This lonely little bacteria will reproduce, making more identical copies of itself with the same mutation.
Eventually, this bacteria will build a colony of millions, all sharing the same genetic mutation allowing them to resist the antibiotics.
This is a simple example of how drug resistance occurs. The only difference is that, instead of 100 bacterial cells, there are trillions. And instead of 1 type of antibiotics, there are dozens.
Every time we use antibiotics – especially if we do it unnecessarily and too often – we favor the bacteria that are able to resist them. Over the years, the bacteria become tougher and harder to fight.
The genetic mutations bacteria have developed that allow them to resist antibiotics can vary, but the most common method is to actually pump the antibiotic out of the bacteria once it gets inside.
This prevents the antibiotic from doing its job and killing the cell.
The specialized pumps on bacteria that do this are referred to as efflux pumps.
These efflux pumps were found in the membranes of many bacteria, but they were designed to remove other compounds from the cell-like toxic metabolic byproducts, and neurotransmitters.
With drug resistance, these pumps are adapted to pump out antibiotics as well.
This finally gets us to the point of this article…
Now that we understand how bacteria can become resistant to antibiotics, we can talk about how cannabinoids prevent it.
Cannabinoids have a wide variety of effects on the human body.
They regulate homeostasis through the endocannabinoid system, stimulate the serotonin receptors to produce the characteristic “high” and activate receptors in the body responsible for muting pain signals.
Cannabinoids also inhibit the efflux pumps on bacteria.
Being fat-soluble compounds, the cannabinoids are able to interact with the fatty membranes of bacterial cells, and possibly alter the way they work.
Research is currently underway to identify these effects in human trials and to better understand the specific mechanism that makes them so effective.
One of the primary studies on these effects looked at the 5 most abundant cannabinoids in the plant: CBD, CBC, CBG, CBN, and THC.
All of these cannabinoids were shown to have the ability to block the efflux pumps in drug-resistant strains of Staphylococcus aureus (MRSA), however, the non-psychoactive cannabinoids CBD and CBG showed the strongest results.
Most of the research currently underway is focusing on MRSA skin infections.
These infections are extremely common in hospitals and are proving to be an emerging global threat.
Topical cannabis salves are tested to inhibit the growth of these bacteria and allow antibiotics to do their job.
Cosmetic companies are also looking at cannabinoids as a new preservative to add to their products to prolong shelf life and resist bacterial colonies from forming.
In the United States, CBD oil is completely legal as long as it doesn’t contain anything above 0.3% THC.
There are a few different options you’re faced with when shopping for any cannabis oil:
CBD isolates are an extraction of the cannabis plant that only includes CBD.
All the terpenes, fiber, plant sugars, and proteins are removed to leave a high-potency CBD extract.
Although this may be effective in treating antibiotic resistance, it’s unlikely that this will offer the same benefit as a product that contains the other phytochemicals, adding its own benefits to the prevention of antibiotic.
Full-spectrum hemp oil is the most recommended product for delivering antibiotic-resistant benefits.
This is because the 2 strongest cannabinoids are the non-psychoactive CBD and CBG, both of which are found in high concentrations in full-spectrum hemp.
In addition to these cannabinoids, the entire phytochemical makeup of the plant is also found in this extract. The terpenes, flavonoids, minerals, and plant sugars can contribute to its effect profile.
THC oils are only available in states that have legalized recreational marijuana. They are also available in countries such as Canada or the Netherlands, that have legal marijuana products for sale.
THC oils often contain a spectrum of cannabinoids, including CBD, CBG, CBC, CBN, and THC, but are referred to as THC oils because they produce psychoactive effects.
If these products are available, and you aren’t opposed to receiving the psychoactive effects of the plant, this may be the best option.
More research is needed to assess the proper dose of CBD oil and other cannabis oils for preventing antibiotic resistance in bacteria.
Most of the current research involves the topical use of the herb for treating skin infections of MRSA.
With that said, the best options are full-spectrum CBD oils, containing as much of the plant’s cannabinoid and terpene content as possible. It also requires high dosing along with a combination of other therapies for best results.
