What Are THC Crystals? How Are They Made?

THC crystals have become a growing topic of interest amongst new and old cannabis users, and one major reason the word is spreading is because of their high potency and heightened cannabis experience. 

This newfound high is quite appealing for recreational and medical users of THC that seek immediate results with lasting effects. In this article, we’ll discover the magic of this substanceand how you can incorporate it into your lifestyle safely and effectively.

What Are THC Crystals?

THC crystal, or crystalline, is processed THC in its purest form. It may also be referred to as THCA, or tetrahydrocannabinolic acid, the non-psychoactive antecedent to THC (tetrahydrocannabinol). 

THC Crystals and Isolated Crystals

THC crystals form spontaneously on cannabis buds, where trichomes—the resin glands—produce small crystalline structures.  These naturally occurring crystals contain a mix of cannabinoids and terpenes that make them impure.

Isolated THC crystals undergo advanced extraction and purification processes in a laboratory to filter out those impurities, leaving behind only the raw, pure THC. 

THC Crystalline vs. THC Diamonds

Typically, people use the term THC crystals interchangeably with THC diamonds or THC crystalline. 

If you do this, you aren’t entirely wrong. THCA diamonds and THC crystalline are the same product. However, THC crystalline is often used to emphasize the purity of other refined cannabis products. 

Other cannabis concentrates like shatter, wax, and live resin offer different varieties of cannabinoids, while THCA diamonds deliver the most concentrated THC content only.

How Are THC Crystals Made?

To make this product, cannabinoids have to be extracted from high-quality cannabis plants rich in THCA. The production of THC crystals is a sophisticated process that requires careful handling of chemicals and specialized equipment, so it’s not something you should try at home. This procedure is best done by professionals in a laboratory setting. 

Although this is a simplified version of the process, you can learn more about the steps below. 

Step#1: Extraction

Organic solvents like butane or propane are used to remove cannabinoid and terpene impurities from the plant material. The plant matter is either soaked or blasted with the solvent in this stage. 

Step#2: Winterization

Next, the mixture is refined through a process known as winterization. 

During winterization, the extract is dissolved in ethanol and left to freeze. This is done to remove unwanted cannabinoids and plant compounds. 

Step#3: Crystallization and Recrystallization

In this step, purified extract is processed into crystal diamonds, which is achieved by dissolving the extract in pentane or hexane. Afterward, it slowly evaporates to allow THCA crystals to form.

Alternatively, the extract can be processed through recrystallization, which involves dissolving the extract into organic solvents continuously to get the highest purity possible. 

Step#4: Separation and Drying

Then, the THC crystals are separated through chromatography and dried to remove any residual solvents, leaving us with a pure end product. 

After the product is ready, lab professionals will conduct quality control tests to ensure that everything has been done properly.

Potential Benefits of THC Crystals

THC crystals have a lot of benefits that cannabis users enjoy. Here are a few:


THC crystals offer the highest levels of THC concentration for consumers. This lowers the risk of consuming harmful substances that are present in less refined cannabis products.

Quantity Control

Because of its high concentration, recreational and medicinal users enjoy an easy-to-regulate dosage control when taking THC crystals.

Side Effects of THC Crystals

THC does have a lot of benefits and uses however, it also has some dormant risks or side effects. As a cannabis user, it is important to know and understand the side effects of THC crystals so you can make informed decisions before consumption. 

The high percentage purity of THC crystals can lead to extreme psychoactive effects, which may include:

  • Paranoia
  • Nausea
  • Vomiting (in the case of high doses)
  • Coordination problems 
  • Visual or auditory hallucinations in extreme cases 
  • Irregular pulse for cannabis users with pre-existing heart conditions. 

Greater tolerance, substance dependence, and other health issues are potential long-term implications of THC crystals if used excessively.

THCA vs. Conventional Cannabis: How Are They Different?

THCa crystals are among the purest forms of cannabinoids available. Conventional cannabis, on the other hand, is unprocessed or minimally processed flowers of a cannabis plant. 

The Difference Between CBD and THC

THC is the main component found in THCA, while CBD is the main component found in conventional cannabis. 

There are notable differences between CBD and THC, and their effects on the body are notable. Because CBD is not psychoactive, it can be used to treat a range of physical or mental medical ailments. 

Meanwhile, adding THC crystals to other cannabis products increases their THC content and is a good way to boost your high.

Decarboxylation: The THC in THCA

Decarboxylation is the process that converts THCA to THC. This chemical reaction occurs when THCA is exposed to heat, such as when smoking or vaporizing cannabis.

Consuming THC crystals or raw cannabis without heating them will not produce the euphoric effects that come with taking cannabis. 

Although the most common method of taking cannabis is smoking, there are other things you can do with cannabis besides smoking it. 


THC crystals are the purest form of THC. They have immense benefits but also come with some side effects that may not make it ideal for some cannabis consumers. Be sure to purchase your THC crystals from licensed businesses to promote responsible use.
