Cannabis compounds: More than just a high

The cannabis plant is a complex source of over 560 compounds, including more than 100 distinct cannabinoids. These compounds interact with the body's endocannabinoid system, which regulates vital functions. Two primary cannabinoids, THC and CBD, are of significant interest for their therapeutic potential, though much remains unknown.

THC, the main psychoactive component, induces a high by activating CB1 receptors in the brain. It offers benefits like chronic pain relief and improved sleep, with synthetic forms approved for chemotherapy-induced nausea and appetite loss. However, high THC doses can lead to severe cyclic vomiting and increase risks for psychosis in predisposed individuals.

CBD, or cannabidiol, does not cause intoxication and has a lower abuse potential. It is effective for epilepsy treatment and is being explored for substance use disorder, pain management, and anxiety. A key advantage is its potential to manage symptoms without causing a high. However, high CBD doses may harm the liver and interfere with other medications.

Historically, cannabis research was hindered by its Schedule I classification. The recent reclassification to Schedule III in the U.S. is expected to facilitate studies. Experts caution that unregulated cannabis products can be contaminated or lack active ingredients. Consulting a healthcare provider before using CBD or THC is recommended.
