Speaking about a recent federal advisory on marijuana, Dr. Jerome Adams, the surgeon general, put a new spin on long-standing admonitions about the drug.
“Marijuana has a unique impact on the developing brain. It can prime your brain for addiction to other substances,” Adams said at a Washington, D.C., substance abuse conference held late in August and sponsored by Oxford House, a recovery center network.
This is a reiteration of the old “gateway” argument: the idea that marijuana is frequently an entree to using other, harder drugs. And the surgeon general’s emphasis comes just as many states are loosening restrictions around its medicinal and adult recreational use.
