Marijuana laws in Maryland have evolved over the last few years, with the state becoming the 21 st in the nation to have a medical marijuana program. In the past, medical marijuana users could prove medical necessity to prevent being convicted for possession of an ounce or less. However, access to medical marijuana was still not addressed. In 2014, then-Governor Martin O’Malley signed a bill into law that replaced criminal penalties with civil fines for possession of 10 grams or less of marijuana. Changes are once again afoot in Maryland, with current laws stating that individuals no longer need to be part of a medical research program to have access to medical marijuana, and can possess a 30-day supply.
