The opposite held truefor the counterparts of inexperienced marijuana smokers, but this fact was very contradicting to everything else I had read to this point.

Marijuana and combinations with other drugs have been growing around the colleges for years. I always thought--yeah, yeah, all the parties and events that go on are the places to find them. This assumption was definitely correct, both at Ann Arbor and in Lansing. The surveys were 100% correct with the inf...
