You are gonna have to back that statement up. Most children over the age of 6 in this country have had a sip of alcohol from time to time. When do they become "experienced"? Is it after you've had your first black out or what?
"Back up" what, that alcohol affects the body from the first sip? That's a simple biochemical fact that I'm surprised you don't understand, apparently. And if you don't understand the body's tolerance of alcohol and other drugs, I think you should read more, post less, on this subject.
Have you ever tried Pot??
