Highland Pharms Crystals 999

There really isn’t much to CBD isolate crystals — by definition, they’re as close to pure CBD as possible. As a result, there really isn’t much difference between these crystals and pure crystals made by another company. With that said, a product’s hemp source matters, and third-party testing can be even more important. When you get CBD this concentrated, if there the hemp source is compromised, the final product may end up with contaminants. 

These crystals by Highland Pharms are top-notch by all of our standards. We highly recommend this product if you’re in the market for high-potency CBD. 

Price/Value 5/5

The price of Highland Pharms Crystals 999 mg is around $0.06 for every milligram of CBD in the container. CBD crystals like these are by far the most cost-effective way to use CBD.

CBD oils usually cost closer to $0.12 per milligram of CBD. When you consider the quality of the hemp and the low cost — this product comes with fair value. 

CBD Potency 5/5

At 99.9% CBD, this is the highest potency possible. This concentrate is so pure it’s forms a crystalline lattice — something only possible in ultra-pure concentrations. 

Hemp Source 4/5

Highland Pharms sources its hemp locally, from local farms in Colorado. The company claims the hemp is non-GMO, organic, and “pharmaceutical grade.” You can find third-party certificates on the website, but organic certificates aren’t (yet) available. Once these certificates are available, this company will be receiving full points for its hemp source. 

Purpose/Uses 5/5

This product is very potent, making it useful for people who need high doses of CBD. The uses for this product are endless — you can use these crystals as they are with a dab rig — or by adding it to your food, coffee, tea, or smoothies. Many people will use these crystals to make their own CBD products like bath bombs, oils, vape oils, capsules, or topicals.

Product Variations 5/5

Crystals 999 are only available in one container size — 1g or 999 mg of CBD (hence the name). We like options— however, for these crystals, we don’t see much value in offering different container sizes, flavors, or potency.

For people who want to order larger quantities, Highland Pharms will offer bulk order deals when you order multiple containers at a time. This is more than enough for a product like this. 

Formulation/Ingredients 5/5

As a pure CBD crystal, there’s no room for anything else in the formula. 

In most other categories of CBD products, we look for products with other ingredients that help direct the effects of a particular product. However, for crystals, it’s better to have nothing but pure CBD — which is why this product gets a five-star rating in this category.

What Are CBD Crystals?

There are many different types of CBD concentrates — such as waxes, shatters, pastes, and these CBD crystals — the names are based on the consistency of the concentrate.

Crystals are the purest form of a concentrate as they don’t contain other cannabinoids, terpenes, or any other organic plant matter. Crystalline CBD is often used in CBD isolate formulas in varying concentrations.

About The Company: Highland Pharms

Highland Pharms is named after the physical location of the company in Highland Lakes, Texas.

Luke Johnston and Eliot Harris began Highland Pharms with the hope of providing a natural replacement for pharmaceuticals, which come with a plethora of undesirable side effects.

Unfortunately, Johnson succumbed to metastatic colon cancer in 2016. CBD had provided him with relief from the side-effects of chemotherapy. Highland Pharms was established to share “hemp oil for cancer, epilepsy or any health condition.”

Highland Pharms obtains its hemp from boutique farms in Colorado before its processed at its facility in Texas and shipped as CBD products throughout the US.

If you’re concerned about a company’s environmental footprint, Highland Pharms uses eco-friendly packaging. This goes a long way in portraying its commitment to sustainable practices.

Who Should Consider Using Crystals 999?

If you’re looking for the highest concentration of CBD possible, crystals are your best bet. Being 99.9% pure CBD, there are no other compounds aside from CBD — no other cannabinoids or terpenes. This is as pure as it gets.

CBD crystals are versatile in that they can be smoked in a dab rig, vaped (in a specialized vaporizer), eaten, and even made into topical formulas.

If you’re new to CBD, crystals might not be the product for you. It can be hard to gauge how much you need, and it’s easy to over-do it. Taking too much can lead to some discomfort.

While CBD is considered safe, even in high doses, it can result in the following side effects:

  • Headaches
  • Dizziness
  • Sedation
  • Low blood pressure
  • Heart palpitations

Cost & Potency

Crystals are an affordable way to use CBD, especially if you require larger doses. It also comes in handy for DIY projects such as edibles and topicals.

Each mg of The Crystals 999 costs just $0.06, which is reasonably priced considering oils and capsules will range between $0.10-$0.16 per mg on average.

Every 1-gram container has 999 mg of CBD. However, we’ve found some inconsistencies with its isolate purity.

One of the third-party results performed by Trace Analytical reported the sample to contain 831 mg of CBD at 83.1% CBD.

Other batches list the potency at 999 mg of CBD at 99% purity. It’s difficult to get 99.9% CBD without wasting a lot of the compound in the process — however, the way we see it, if you’re going to market the product as having this much CBD, you need to consistently deliver this amount no matter how inefficient the extraction may be at times.

We should note that although we did find an inconsistent test, the vast majority of the third-party tests on the company website do indeed show 99.9% purity.

Both lab results show 0% THC or any other cannabinoid — making this a pure CBD isolate.

Hemp Source

Highland Pharms sources its hemp crops from organic growers in Colorado. However, it’s not a USDA certified-organic hemp source. As the USDA certification becomes more available for hemp crops throughout the states, we expect to see Highland Pharms receive an organic certification too.

“Pharmaceutical-grade” is often tossed throughout the website as a selling feature for Highland Pharms products. To be clear, there is only one pharmaceutical CBD product on the US market, Epidiolex.

The pharmaceutical-grade crops refer to the strain of hemp grown. It’s bred to contain high levels of CBD and low levels of THC. The growing practices are also stricter for hemp used for human consumption over industrial textiles.


This ultra-purified CBD requires control over how you’re using it. It only takes a few extra milligrams of this stuff to push the dose way over the desired level. For this reason, most people will either dissolve their CBD crystals into the oil to dilute it. Others will use it to make their own CBD products like topicals, bath bombs, edibles, capsules, vape oils, and much more.

You can also add these crystals to other CBD products to increase their potency.

Highland Pharms recommends adding CBD crystals to food and drinks. If you’re looking to get the fastest effects from CBD, you can smoke this in a dab rig or specialized vaporizer.

Keep in mind this is a highly concentrated product, so it’s worth getting tools like a small scale or a pre-measured spoon to measure your doses.

How Does Highland Pharms Extract 99.9% Pure CBD?

Like most other CBD manufacturers, Highland Pharms uses supercritical CO2 to make its extracts.

The CO2 pulls out the majority of the phytochemical profile of the plant, leaving behind the unwanted fibers, larger proteins, and long-chain carbohydrates. Once the pressure is released, the CO2 evaporates out of the extract — leaving behind pure cannabis phytochemicals.

At this stage, the product still contains all the other cannabinoids, terpenes, and other plant compounds contained in the hemp plant. Another process is required to isolate the CBD by essentially pulling out all non-CBD compounds. This is done through various stages of processing and refining like short-path distillation.

This process needs to happen several times to increase the potency to the 99.9% level. Each time the extract is purified, some product is lost. It’s in the company’s best interest to use the most efficient purification techniques possible.

Highland Pharms Shipping & Return Policy

Highland Pharms offers free shipping in the United States. If you live outside of the US, you’ll have to look elsewhere for your CBD Capsules because Highland Pharms does not ship outside the United States, Puerto Rico, or the US Virgin Islands.

You may request a full refund within 30 days of purchase. However, this does not apply if you purchase your products in bulk to benefit from the discount.

Final Verdict: Great Affordable CBD Crystals

Highland Pharms Crystals 999 is an excellent option for people looking for the purest form of CBD — it doesn’t get any purer than this.

This product can be added to foods, beverages or other CBD products such as vape juices to increase the CBD concentration or you can use it alone in capsules, under the tongue, or smoked using a dab rig.

In terms of price, this is one of the cheapest ways to use CBD at just $0.06 per mg of CBD. This compares to most oils which fall in the range of $0.10 – $0.17 per mg of CBD.
