The term medical marijuana refers to using the whole, unprocessed marijuana plant or its basic extracts to treat symptoms of illness and other conditions.

However, scientific study of the chemicals in marijuana, called cannabinoids, has led to two FDA-approved medications. Continued research may lead to more medications.
Because the marijuana plant contains chemicals that may help treat a range of illnesses and symptoms, many people argue that it should be legal for medical purposes. In fact, a growing number of states have legalized marijuana for medical use.
Some preliminary studies have suggested that medical marijuana legalization might be associated with decreased prescription opioid use and overdose deaths, but researchers don’t have enough evidence yet to confirm this finding. For example, one NIDA-funded study suggested a link between medical marijuana legalization and fewer overdose deaths from prescription opioids.
