There are, however, standardized tests to screen for current substance abuse. These tests are most accurate on adults, but may also be used on teens. The most widely used test is the CAGE questionnaire. Substance abuse and addiction usually start in the teenage years. Many teenagers abuse substances as a way of coping with physical, emotional, and social changes common at that stage of life.
Studies show that there is a correlation between parent-child communication and substance abuse.
Teens who regularly talk to their parents about problems have the lowest rate of substance abuse, while teens who never talk to their parents have the highest rate. Other studies have found that parent-child communication can offset the influence of friends on teen substance abuse. Substance abuse can be treated after it is part of a person's life. There are similar meetings for people who are addicted to other substances. This reinforces the idea that substance abuse can be treated, but not cured.
