The use of cannabis for both legal (similar to alcohol) and medical purposes is becoming more common. Although cannabis remains an illegal Schedule 1 drug federally, as of November 2015, 23 states and the District of Columbia have legalized “medical” cannabis, and 4 states and the District of Columbia have legalized the use of cannabis for adults aged 21 years and older. It is very likely that more and more states will sooner rather than later allow cannabis for both medical and legal purposes.

- Definitions of cannabis/cannabinoids/related; cannabis delivery methods
