Congress took a step toward easing its stance on medical marijuana on Thursday.
U.S. Sens. Rand Paul (R-Kentucky), Corey Booker (D-New Jersey) and Kirsten Gillibrand (D-New York) introduced a bill that would end the federal prohibition of medical marijuana and take steps to improve reearch.
The Compassionate Access, Research Expansion and Respect States, or CARERS, Act would effectively change the Controlled Substances Act, allowing the possession, production and distribution of medical marijuana in states with established marijuana laws.
