Teenagers who have easy access to drugs and alcohol in the home are more likely to drink and do drugs in their early and late 20s. That’s according to the one of the first studies to look at how adolescent exposure to illegal substances affects patterns of abuse in adulthood.

The national study, by Michigan State University’s Cliff Broman, also indicates that the effects were more significant among white people and males.

“While there have been many studies linking alcohol and drug use by parents to substance use among youths, there is limited research on how the availability of alcohol and drugs in the home may influence patterns of use among offspring in the future,” said Broman, professor of sociology.

“These findings provide evidence that the availability of illegal drugs and alcohol in the home while growing up is a critical factor in the later use of substances.”
