Cannabis plants vary widely, with different strains producing dynamic balances of cannabinoids (THC, CBD, etc.) and yielding markedly different effects. Popular strains are often hybrids of C. sativa and C. indica. The medicinal effects of cannabis are widely studied, and are active topics of research both at universities and private research ...
