Cannabis Studies: Cannabis Terms and Concepts


The genus Cannabis is often divided into two species: C. sativa—the hemp varieties that sprout narrow leaves and grow tall—and C. indica, whose shorter stature, denser branches, and higher concentrations of psychoactive ingredients made it the choice for recreational and medicinal use.
