Youth regularly receive pro-marijuana tweets

Hundreds of thousands of American youth are following marijuana-related Twitter accounts and getting pro-pot messages several times each day, according to researchers at the School of Medicine. They said the tweets are cause for concern because young people are thought to be especially responsive to social media influences and because patterns of drug use tend to be established in a person’s late teens and early 20s.

Early substance use linked to lower educational achievement

School of Medicine researchers have found evidence that early drug and alcohol use is associated with lower levels of educational achievement. They found that people who began drinking or using drugs as young teens or who became substance dependent were less likely to finish college.
