What Are THC Crystals On Weed? A Quick Guide

THC crystals on weed—also known as weed crystals, diamonds, or crystalline—are a concentrated form of cannabis that resembles the coarse decorating sugar a baker might use to top cookies. More specifically, they’re an isolate. Despite the name, these crystals actually only contain THCa, the non-psychoactive precursor to THC. 

How Are Weed Crystals Formed?

The making of THC crystals starts with raw cannabis flowers. Using acetic acid extraction, processors first separate cannabinoids and other compounds from the plant material. Then, they refine the extract until only THCa remains. The single cannabinoid undergoes a process to remove any lingering solvents. Finally, solid crystals — THC crystals — begin to form. 

Weed Crystals Vs. Trichomes

If you’ve ever looked closely at a cannabis flower, you’ve likely noticed crystalline-like structures on it. These are trichomes — hair-like glands that contain the bud’s cannabinoids, terpenes, and other compounds. Although you may hear some people refer to them as crystalline on weed, they are not the same thing as THC crystals. Trichomes occur naturally on cannabis plants, while THC crystals are lab-made. 

How to Use THC Crystals

One of the best things about weed crystals is that they’re incredibly versatile. You can use them in a variety of ways to enjoy more intense experiences with cannabis. 


Add THC crystals to the ground buds in your joint or spliff to enhance the potency of your chosen strain. Alternatively, you can smoke weed crystals by themselves in a pipe, bong, or similar bowl. 


Like other concentrates, you can apply THC crystals to the nail of your dab rig for an intense, near-instant high. 

Homemade Edibles

Melt weed crystals in oil or butter. You can then use the infusion to make all kinds of delicious – and potent — homemade edibles. Some options include:

  • Baked goods like cookies, brownies, and cupcakes
  • Cake frosting
  • Salad dressings and marinades
  • Sauteed vegetables 

Note: You can consume THC crystals raw, but they won’t produce the same high as they will when heated. However, they may still deliver some of the potential benefits of THCa.


Another option to consider is infusing a homemade skin cream or lotion with THC crystals. Similar to edibles, you can melt the crystals into the oil you plan to use for your topical before combining your ingredients. One note here is that these products won’t get you high, as the cannabinoids don’t penetrate the skin deep enough to enter the bloodstream. 

Quick Tips for Using Crystalline On Weed

  • Heat is your friend. Remember, THC crystals on weed are technically THCa. You’ll need to expose them to heat to convert THCa into THC and unlock their potency. 
  • Start small. Like other concentrates, THC crystals are much more potent than other cannabis products. Start with a small amount and make adjustments gradually. That way, you can create optimal experiences and avoid greening out
