The move by drug companies to make abuse-proof prescription painkillers may be inadvertently promoting heroin use, a new study found. The study of more than 2,500 people with opioid dependence found a 17 percent drop in OxyContin abuse with the 2010 arrival of a formula that’s harder to inhale or inject. During the same time period, heroin abuse doubled.
Unlike its predecessor, the abuse-deterring version of OxyContin turns to gel when crushed, making it harder for people to snort or inject for a rapid high. But nearly a quarter of study participants found a way around the formulation tweak, and 66 percent said they switched to another opioid – usually heroin.
