None of this is "statistical data." Self-reporting is not a valid method in teens, IMHO. Or maybe generally. I just know that when I got that little pop quiz I decided to lie.... To lie in a way that suited my purposes which was to be stealthy.
Also if we're going to get into illicit drug use, well, in Tucson, they'd better start doing the "survey" at around age 10, frankly. Sad but true.
Do I trust a "self-report" survey that the "government conducts"??? Nope, no I do NOT. If it doesn't say what the government WANTS, then really, they will figure out a way to skew it. I really.... just argh.
