Cannabinoid-based drug discovery and development refer to the scientific process of identifying, designing, and bringing to market medicines that act on the body’s endocannabinoid system (ECS) using compounds derived from Cannabis sativa (like THC and CBD), their synthetic analogs, or newly engineered molecules that target cannabinoid receptors (CB1, CB2) and related pathways. These efforts span basic research, medicinal chemistry, preclinical testing, and clinical trials, with the goal of proving safety and efficacy for therapeutic use in regulated medical settings.
