James Shroba directs the St. Louis Division of the DEA. He says there is a direct link between prescription drug abuse and the use of illegal drugs like heroin.
"Because first time drug users between the ages of 12 and 19 enter into that cycle of abuse by trying the legally-prescribed medications that are sitting in the medicine cabinet," says Shroba.
According to a survey by the U.S. Department of Health and Human Services, more than two-thirds of people abusing prescription drugs got them from a friend or family member.
