Many teens try alcohol, tobacco, or drugs. Some teens try these substances only a few times and stop. Others can't control their urges or cravings for them. This is substance use disorder. Moderate to severe substance use disorder is sometimes called addiction.

Teens may try a number of substances, including cigarettes, alcohol, household chemicals (inhalants), prescription and over-the-counter medicines, and illegal drugs. Teens use alcohol more than any other substance. Marijuana is the illegal drug that teens use most often.

Why do teens use drugs and alcohol?

Teens may use a substance for many reasons. They may do it because:

  • They want to fit in with friends or certain groups.
  • They like the way it makes them feel.
  • They believe it makes them more grown up.

Teens tend to try new things and take risks, so they may take drugs or drink alcohol because it seems exciting.

Teens with family members who have problems with alcohol or other drugs are more likely to have serious substance use problems. Also, teens who feel that they are not connected to or valued by their parents are at greater risk. Teens with poor self-esteem or emotional or mental health problems, such as depression, also are at increased risk.
