those i have known, including a number of friends and a couple of distant family members who dabbled in drugs, did so from early teens, they also drank but not in large quantities, drugs became not just the odd spliff, but uppers and downers, then more pills, then onto the harder stuff, heroin, LSD, leaving life long habits, and leaving me with a lifelong hatred of drugs, it can happen to anyone, anywhere. Drinking as they say is legal, and does have lots of knock on effects to those who drink heavily and their families and friends. Having seen more friends die through drink, not sure which i would class as the real problem.
