Addiction is a pediatric disease," says Dr. John Knight, founder and director of the Center for Adolescent Substance Abuse Research at Boston Children's Hospital. "When adults entering addiction treatment are asked when they first began drinking or using drugs, the answer is almost always the same: They started when they were young — teenagers," said Knight.
Smoking, drinking and some forms of drug use among teens have declined in the U.S. in recent years, but an estimated 2.2 million adolescents — 8.8 percent of youth aged 12 to 17 years old — are currently using an illicit drug, according to a 2014 Behavioral Health Barometer prepared for the Substance Abuse and Mental Health Services Administration (SAMHSA).
Drug use changes brain development, and when substances are used during adolescence, young people are much more likely to become addicted, Knight said. "When people start using at younger ages, the changes in brain structure and function are very, very pronounced," he explained. "If we could only get kids to postpone their first drink or their first use of drugs, we could greatly diminish the prevalence of addiction in the U.S."
