In fact, last year Northwestern researchers found that teenagers who smoke marijuana had abnormal brain changes that affected their working memory. Their brains actually changed shape, collapsed inward, and shrunk. They performed poorly on memory tests. And worse yet, these brain abnormalities and memory changes remained years after the teenagers stopped smoking marijuana. So the damage is profound–and permanent.

I saw an article earlier speaking of decreased crime rate in legalized states.
If I can find, I'll post.

like any other medicine, idiots will abuse it, if used properly it does amazing things to bring the body back into balance, as well as eradicate cancer & a host of other disease, the pharmacy is not amused...

I don't think teens should be allowed to consume alcohol, tobacco, or marijuana.  Only adults from 21 yrs. on have that option, IMHO.  I would even question high doses of caffeine, or excessive sugar consumption for that matter, for anyone under the age of 18.  However, this & that should be under the discretion of parents though, again, IMHO.
