Opioids are derived from the latex of the opium poppy plant, Papaver somniferum. They bind to specific opioid receptors present in the central nervous system and gastrointestinal tract, acting as depressants that slow down overall body functions and relieve pain (e.g., morphine and heroin). Cannabinoids are extracted from the inflorescences of Cannabis sativa. They interact with cannabinoid receptors principally located in the brain and primarily affect the cardiovascular system of the body, altering perception, mood, and consciousness.
