It's clear that kids who use marijuana are more likely to use other drugs, than kids who don't use marijuana. There's no doubt about that. About that we simply don't know. There any many different ways in which you could imagine marijuana being a gateway to the use of other drugs. It might be a step toward illegal behavior, and therefore other illegal behavior tends to follow.
People talk about age restrictions, leaving it illegal for kids.
Well, wait a minute. You can't have it both ways. I actually think the age restriction for alcohol is now a major problem. I used to be a fan of age restrictions, I've now completely switched, views on that. And, I was, struck by a bolt of insight on the road , not to Damascus, but the Worcester, Massachusetts.
