Your opinion on the three studies is invalid due to your fanatical opposition to drug legalization.
Isn't ad hominem fun?
You crave drugs,
Wrong.
so you reject all studies that show the great harm of drug use.
Wrong again. I agree that using drugs - including alcohol and tobacco - can be harmful.
Your posts are meaningless, as these studies look at periods of time and the commonality of illegal activity and drug use.
You made the claim that drug abuse was rising up to 100% before the studies, and then refuse to offer why...
If my head explodes it will be from laughing at you.
