Information:

Learn about the different types of drugs that may be used.

Older teens are more likely to use drugs than younger teens. Marijuana (pot) is still common. More and more teens are using prescription drugs.

  • About 1 out of 7 high school seniors have used prescription drugs.
  • About 1 out of 3 have used marijuana in the last year.
  • Younger teens use drugs that are inhaled more than older teens.

Keep your eyes open for signs of drug use. Physical signs include:

  • Slow or slurred speech (from using downers and depressants)
  • Rapid, explosive speech (from using uppers)
  • Bloodshot eyes
  • Cough that does not go away
  • Unusual odor on breath (from using inhalant drugs)
  • Pupils are extremely big (dilated) or extremely small (pinpoint)
  • Rapid eye motion (nystagmus) -- a possible sign of PCP use
  • Loss of appetite (occurs with amphetamine, methamphetamine, or cocaine use)
  • Increased appetite (with marijuana use)
  • Unsteady gait

There may be noticeable changes in your teen's energy level. You may notice:

  • Sluggishness, listlessness, or constant sleeping (from using opiate drugs, such as heroin or codeine, or when coming down off stimulant drugs)
  • Hyperactivity (as seen with uppers such as cocaine and methamphetamine)

Your teen's behavior may change. You may notice:

  • Poor grades in school and missing more school days
  • Not taking part in usual activities
  • Change in group of friends
  • Secretive activities
  • Lying or stealing

Get help early for your teen. Help them stop using drugs before it becomes a more serious problem.
