The former Maryland governor met with Colorado officials and marijuana activists and business owners in Denver Thursday. He repeated his pledge to reclassify marijuana under federal drug laws if elected.
Reclassification could open the door to doctors being able to prescribe marijuana, which currently has no accepted medical use under federal law. Such a change would place the drug under federal control, not the states. But O'Malley also said he wants to see how Colorado's marijuana experiment turns out.
Last year O'Malley signed a Maryland law decriminalizing small amounts of pot.
