Many parents want to know what to look for in their teenager that might indicate he/she is using drugs or alcohol. There are some signs that might indicate your teen is using. It’s important to keep in mind, however, that if your teen is displaying the following behaviors, it doesn’t mean he/she is definitely using a substance. Remember, as teenagers, behavior changes are expected. If, however, you do notice more than a few of the signs below, either have a serious talk with your teen or contact someone who can help - a guidance counselor at school, a substance abuse center, pediatrician, etc.
