What drug, or drugs make the user pick at their face to the point of making sores?
Update: Heroin is the answer. Keep an eye on your children, heroin use is on the rise in this country and it is a horrible drug. It is very easy to hide, that is until they become full blown addicts and the damage has already been done. Dont give them the benifit of the doubt, search thier rooms carefully, and often!
