Cannabis contains hundreds of compounds — the most studied being THC (psychoactive) and CBD (non-psychoactive) — with significantly different effects on the body and distinct therapeutic profiles. Evidence supports cannabis-based treatments for a narrower range of conditions than popular enthusiasm suggests (chronic pain, certain forms of epilepsy, chemotherapy-associated nausea), while research into other applications is ongoing and evolving rapidly. The risks — particularly for adolescent brain development, with heavy chronic use, and in people with certain psychiatric vulnerabilities — are real and deserve honest acknowledgment alongside the potential benefits.
Each step builds on the last.
