The nature of the survey questions are relevant. Pot has always been, and is, illegal for kids to smoke. Who's going to fess up to breaking the law?
So we should therefore not believe kid survey’s regarding alcohol as well? Again, what are you experiences/qualifications to make such a statement?
I mean either kids can be scientifically surveyed or they can’t. Since kids have been surveyed over the years with scientific reliability why are they suddenly unbelievable?
