Bring in other members of the family to help, if necessary. Discuss drug use with your children and establish family rules. More information about setting and enforcing rules can be found in The Parent's Role section of this site. Impose whatever course of discipline your family has decided on for violating the rules and stick to it. Don't relent because your child promises never to do it again.
Many young people lie about their alcohol and other drug use.
If you decide to go this route, remember that you're trying to help your child. Don't make a visit to the doctor seem like a threat or a punishment. If your child has developed a pattern of drug use or has engaged in heavy use, you will probably need help to intervene. If you do not know about drug treatment programs in your area, call your doctor, local hospital, state or local substance abuse agencies, or county mental health society for a referral. Your school district should have a substance abuse coordinator or a counselor who can refer you to treatment programs, too.
