The endocannabinoid system is a signaling network in the brain and body. It includes cannabinoid receptors and chemicals the body makes called endocannabinoids. These signals help regulate functions such as appetite, memory and pain processing. THC can act on cannabinoid receptors and alter normal signaling.

Understanding this system does not establish that cannabis safely treats every condition. Benefits and risks depend on the condition, product and individual. Review treatment decisions with a qualified clinician.

THC and CBD are cannabinoids found in cannabis. THC is intoxicating and can impair attention, memory and coordination. CBD does not produce the same high, but it is not risk-free: it can interact with medicines and may cause liver injury. THC and CBD are distinct from their acidic precursors, THCA and CBDA.

Evidence of benefit varies by condition and preparation. FDA-approved cannabinoid medicines are specific prescription drugs; their approval does not mean dispensary products have been FDA-approved to treat disease. Discuss medicines, side effects and treatment alternatives with your clinician. Do not drive while impaired.

Terpenes are aromatic compounds found in cannabis and many other plants. They contribute to scent and flavor. Researchers are studying their biological effects, including possible interactions with cannabinoids, but human evidence is still limited.

A terpene profile or strain name does not reliably predict a therapeutic result, a particular mood or how a product will affect an individual. Laboratory and animal findings should not be presented as proven treatments in people.
