“Illegal use of prescription pain drugs increases a person’s risk of becoming a heroin user, a U.S. government report suggests.
The researchers found that Americans aged 12 to 49 who had used prescription pain relievers illegally were 19 times more likely to have started using heroin within the past year than other people in that age group. Nearly 80 percent of people who recently started using heroin had previously used prescription pain relievers illegally, the U.S. Substance Abuse and Mental Health Services Administration report added.
It also noted, however, that only 3.6 percent of people who had illegally used prescription pain medicines started using heroin within five years.”
