Scott Morgan has a good post: Why Legalizing Marijuana Protects Young People, where he quotes from a parent in Psychology Today:
As a parent, I ask myself, “what are the dangers to teens?” And, what are the likely scenarios? If pot is still illegal to anyone under 21, how will teens get it? I think the most likely scenario is the same as beer and cigarettes. Older brothers and sisters, with IDs, will legally buy packaged marijuana cigarettes at gas stations and share them with younger ones on Friday night parties. As a parent, I ask myself, “how do I feel about this?” And… after a little thought, I actually feel better knowing my child is with trusted friends, ingesting measured substances than on a corner at night buying an illegal substance from a stranger.
Exactly – a rational thought process.
One additional benefit that parents might consider. Under prohibition, if their child has a joint and is caught, the consequences can be much worse to their future.
