The booklet first notes the adverse effects of marijuana, a prevalent drug used by teens, and alcohol, followed by a listing of the signs of substance abuse. These include an adverse change in school performance, increased secrecy about their possessions and activities, new friends, evidence of drug paraphernalia such as pipes and rolling papers, and a lack of interest in personal appearance. If parents suspect their child may be using drugs or alcohol, the first step is to gain knowledge about actions to take. Sources of good information are recommended in this booklet. This should be followed by a sit-down conversation with the child in a calm atmosphere. Express your concern about any negative changes observed in the child's behavior and the possibility they may be caused by drug abuse. Refrain from making the discussion an inquisition or a lecture and focus on concern about the detrimental effects of drug use and your intention to do what is necessary to help them stop their drug use. Be prepared for denials and anger, but remain firm in setting appropriate rules that will make any drug use difficult for the child. A recommended approach is to take the child to the doctor or talk to the school nurse about screening him/her for drugs and alcohol. A list of resources for parents in dealing with a child's drug and alcohol abuse is included.
