Yeah, meth is serious shit, but this attitude that once anyone touches it they're immediately addicted, loose all their teeth and age fifty years in a week is just more of the same old bullshit anti-drug claptrap. It convinces people who have never been around drugs, but that's about it. A little honesty in drug education just might be a bit more effective.
Of course, if Agassi lost all his teeth, I stand corrected...
