I'm a little worried about my teenage daughter. What are some signs of teen substance abuse?

Some possible signs of teen substance abuse include changes in behavior, including increased irritability, restlessness, or depression; spending more time with friends who use drugs; using drugs to cope with stress; and missing school due to drug use. Other potential warning signs include frequent absences from home, poor grades, lying about activities, stealing money or possessions, and running away from home.
