Warning Signs of Drug and Alcohol Abuse

Do you know the warning signs of drug and alcohol abuse? As a parent, you should!

Not my kid!

It can happen to you. We must understand that in modern society, every child is in danger of getting involved with drugs, nicotine or alcohol.

The mood swings and unpredictable behavior that most teens experience makes it difficult for parents to tell if a child is using drugs. The anti-drug education our kids get in school barely counters the "street education" they pick up from peers and our culture.

What are the signs that your child is experimenting with drugs or alcohol, or is at risk of doing so?
