Making Medical Marijuana Legal Under Federal Law: The Compassionate Access, Research Expansion, and Respect States (CARERS) Act, introduced by Senators Rand Paul (R-KY), Cory Booker (D-NJ), and Kirsten Gillibrand (D-NY), would make production, distribution, and possession of marijuana for medical purposes that’s legal under state law legal under federal law. The bill would also remove barriers to scientific research, allow Veterans Administration physicians to recommend medical marijuana, allow interstate transportation of CBD oils, ensure medical marijuana dispensaries are taxed fairly, and allow all marijuana businesses — including adult-use stores in Colorado and elsewhere — to access the banking system and no longer be forced to operate on a cash-only basis.
