(USA Today) One of the nation's top scientists raised concerns about the nationwide move to legalize marijuana, saying regular use of the drug by adolescents had been tied to a drop in IQ and that a possible link to lung cancer hasn't been seriously studied.
"I'm afraid I'm sounding like this is an evil drug that's going to ruin our civilization and I don't really think that," Francis Collins, director of the National Institutes of Health, said Thursday. "But there are aspects of this that probably should be looked at more closely than some of the legalization experts are willing to admit."
