Endocannabinoid system
The network of receptors and signaling molecules in the human body that cannabinoids interact with, helping regulate mood, appetite, pain, and sleep. THC works by mimicking the body's own endocannabinoids at CB1 and CB2 receptors. This system is why cannabis affects so many different functions at once.

- Cannabinoid
- One of the chemical compounds produced in cannabis that interact with the body's endocannabinoid system. THC and CBD are the best known, but the plant makes over a hundred, including CBN, CBG, and CBC. Together with terpenes, cannabinoids drive the effects you feel from any given product.
- THC
- Tetrahydrocannabinol, the primary intoxicating compound in cannabis and the source of the classic "high." THC binds CB1 receptors in the brain, producing euphoria, altered perception, and appetite. Potency is listed as a THC percentage on most labels, though terpenes and dose shape the actual experience as much as that number.
- CBD
- Cannabidiol, a non-intoxicating cannabinoid widely used for calm, recovery, and general wellness without producing a high. CBD can soften some of THC's edge and is sold on its own as oils, gummies, and topicals. It is the most studied cannabinoid after THC and the basis of many medical products.
