Trichomes are tiny, hair-like structures that grow on the cannabis flower. They look like small crystals and make and store many of the plant’s natural chemicals, including tetrahydrocannabinol (THC), cannabidiol (CBD), and terpenes.

Trichomes have more than one role. For the cannabis plant, they act as a natural defence, protecting against pests, fungi, and harsh environmental conditions. For patients, trichomes matter because they hold cannabinoids and terpenes — the compounds that give medical cannabis its effects and aroma.
Yes. Trichomes are the main site where THC is produced and stored in the cannabis plant. The amount of THC present varies between different plants and products.
Trichomes do not cause a “high.” However, they contain cannabinoids such as THC, which can have euphoric effects when consumed in sufficient quantities. Whether a patient experiences these effects depends on the product prescribed, the cannabinoid profile, the method of administration, and how much is consumed.
Yes. Like THC, cannabidiol (CBD) is also produced and stored within trichomes. The balance of CBD, THC, and other cannabinoids will depend on the specific variety of cannabis and how it has been cultivated.
