According to this chart by GOOD and Column Five, drug use among young American youth is not as bad as it was in the 1990s.
While it seems that the use of marijuana has drastically increased since the 1990s, other forms of illicit drug use has slightly decreased. For example, ecstasy, hallucinogens and inhalants have gone down in terms of usage while other drugs such as cocaine and tranquilizers have remained the same.
Surprisingly, the use of alcohol and cigarettes has drastically decreased since the 90s. When comparing Europeans to Americans, the Europeans consume more alcohol and cigarettes, while American youth have a higher rate of illicit drug use.
These are important statistics to be aware of, as more preventative measures can be taken to help steer teenagers away from health-deterring drugs.
