Genetic variation within the endocannabinoid system may explain why some survivors of childhood adversity go on to become dependent on marijuana, while others are able to use marijuana without problems, suggests new research from Washington University in St. Louis.

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.

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.
