Substance Abuse
Teens with alcohol and drug problems are also more at risk for suicidal thinking and behavior. Alcohol and some drugs have depressive effects on the brain. Misuse of these substances can bring on serious depression. That’s especially true for some teens who already have a tendency to depression because of their biology, family history, or other life stressors.

The problem can be made worse because many people who are depressed turn to alcohol or drugs as an escape. But they may not realize that the depressive effects alcohol and drugs have on the brain can actually intensify depression in the long run.

In addition to their depressive effects, alcohol and drugs alter a person's judgment. They interfere with the ability to assess risk, make good choices, and think of solutions to problems. Many suicide attempts occur when a person is under the influence of alcohol or drugs.

This doesn’t mean that everyone who is depressed or who has an alcohol or drug problem will try to kill themselves, of course. But these conditions — especially both together — increase a person’s risk for suicide.
