As healthcare providers and physicians, we increasingly see patients using medical marijuana in our clinical practices. While medical marijuana was historically shunned due to its classification as a Schedule I drug, its variable potencies and unpredictable patient responses, modern medical marijuana has made significant inroads in medical practice. Currently, in the United States, a total of 31 states, the District of Columbia, Guam and Puerto Rico allow public medical marijuana and cannabis programs. In addition, another 15 states allow the medical use of low THC, high cannabidiol (CBD) products.
