Argument: Medical marijuana can act as a gateway drug to harder ones
Peter Provet, PhD, President and Chief Executive Officer at the Odyssey House, Letter to the editor of the New York Times. Apr. 26, 2006: "As a treatment provider, I support the Food and Drug Administration's dismissal of medical benefit from marijuana. Regardless of the heated political debate that swirls around this issue, the fact remains that despite the Institute of Medicine's claim to the contrary, for people vulnerable to addictive disease, marijuana is a gateway drug that leads to the use of more dangerous drugs like cocaine and heroin. Not everyone who smokes marijuana will necessarily become an addict. But why open the gate to increased use for the sake of unproven medical benefits when we already know the harm that marijuana inflicts on millions of Americans."
