As of this writing, marijuana is becoming increasingly legal and accepted in the United States on a state-by-state basis.
Approximately 22.2 million Americans use marijuana each month, whether illegally or legally for medicinal or recreational purposes.
However, despite widespread use, marijuana is potentially addictive and harmful, especially when used by young people or women who are pregnant or breastfeeding. Between 9% and 30% of those who use marijuana develop some form of problematic marijuana use disorder.
