Nevertheless, allowing it in a medical setting can be done without legalizing it across the board. Medicine must be prescribed by a physician whilst the general public cannot buy prescription medicine without a medical prescription. I can understand and perhaps support an effort to legalize narcotics for medical purposes (i.e. with a prescription) without legalizing it across the board.
Do supporters of narcotic legalization efforts also support that prescription medicine be made available to anyone for any reason with or without a prescription? To be consistent, they would need to support that position.
