Signs of Substance Abuse by Teens
Posted: Jan. 1, 2008
The physical signs of abuse or addiction can vary depending on the person and the drug being abused. In addition, each drug has short-term and long-term physical effects.
For example, someone who abuses marijuana may have a chronic cough or worsening of asthmatic conditions. Stimulants like cocaine increase heart rate and blood pressure, whereas opioids like heroin may slow the heart rate and reduce respiration.
Parents should be aware of changes in their child’s behavior, although this may be difficult with teens. Parents should look for withdrawal, depression, fatigue, carelessness with grooming, hostility and deteriorating relationships with family members and friends.
In addition, changes in academic performance, increased absenteeism or truancy, lost interest in sports or other favorite activities, and changes in eating or sleeping habits could be related to drug use. However, these signs may also indicate problems other than use of drugs.
