Legitimate Use of Medicinal Marihuana Act or LUMMA This bill transfers marijuana from schedule I to schedule II of the Controlled Substances Act. It also specifies that no provision of the Controlled Substances Act prohibits or restricts activities related to medical marijuana that comply with a state's medical marijuana law. The bill does not affect any federal, state, or local law that regulates or prohibits smoking in public. Under current law, schedule I controlled substances are those that, among other factors, have no currently accepted medical use in treatment in the United States; such substances thus may not be prescribed, administered, or dispensed for medical use. Substances listed in schedules II through V have some accepted medical use and thus may be prescribed, administered, or dispensed for medical use.
