Cannabis is a genus of flowering plant that has been used for thousands of years for medicinal, spiritual, and recreational purposes. Its primary psychoactive constituent is delta-9-tetrahydrocannabinol (THC), though dozens of additional cannabinoids and terpenes contribute to its overall effects. It ranks among the most widely consumed recreational substances globally, behind only alcohol, caffeine, and tobacco. Its two principal species, sativa and indica, are recognized for producing distinct effect profiles.
