It’s become a popular myth – and for some, a propaganda tool – to claim that opioid pain medication is a gateway drug to heroin and other street drugs.
An opioid education campaign called The Truth About Opioids – funded with taxpayer dollars from the White House Office of National Drug Control Policy — declares in big bold letters on its website that “80% of heroin users started with a prescription painkiller.”
The 80% figure stems from a 2013 study that found four out of five new heroin users had previously abused prescription opioids by using them non-medically.
Importantly, the heroin users were not asked if they had a valid prescription for opioids or even where they got them – but that doesn’t stop federal agencies from citing the study as proof that illegal drug use often starts with a legal opioid prescription.
The Drug Enforcement Administration last year used the 80% figure to justify steep cuts in the supply of prescription opioids, claiming in the Federal Register that addicts often get hooked “after first obtaining these drugs from their health care providers.”
“The 80% statistic is misleading and encourages faulty assumptions about the overdose crisis and medical care,” Roger Chriss explained in a PNN column last year.
A new study by researchers at Penn State University debunks the myth that the opioid crisis was driven primarily by doctors’ prescriptions. The researchers conducted a series of surveys and in-depth interviews with opioid abusers in southwestern Pennsylvania -- a region hard hit by opioid addiction -- asking detailed questions about their drug use.
The study was small – 125 people were surveyed and 30 of them were interviewed – but the findings provide a an important new insight into the origins of opioid abuse and the role played by painkillers.
"What emerged from our study -- and really emerged because we decided to do these qualitative interviews in addition to a survey component -- was a pretty different narrative than the national one,” said lead author Ashton Verdery, PhD, an assistant professor of sociology, demography and social data analytics at Penn State. "There's a lot about that narrative that I think is an overly simplistic way of thinking about this."
‘Opioids Were Never the First Drug’
Verdery and his colleagues found that over two-thirds of those interviewed (66.7%) first abused a prescription opioid that was given, bought or stolen from a friend or family member. Another 7% purchased the drugs from a stranger or dealer. Only one in four (26%) started by abusing opioid medication that was prescribed to them by a doctor.
“We found that most people initiated through a pattern of recreational use because of people around them. They got them from either siblings, friends or romantic partners," said Verdery. “Participants repeatedly reported having a peer or caregiver in their childhood who had a substance use problem. Stories from childhood of witnessing one of these people selling, preparing, or using drugs were very common. Being exposed to others’ substance use at an early age was often cited as a turning point for OMI (opioid misuse) and of drug use in general.”
And prescription opioids were not the gateway drugs they are often portrayed to be. Polysubstance abuse was common and usually began with drugs such as alcohol, marijuana, cocaine, methamphetamine, prescription sedatives and prescription stimulants.
“It is important to note that interviewees universally reported initiating OMI only after previously starting their substance use career with another drug (e.g., alcohol, marijuana, cocaine). Opioids were never the first drug used, suggesting that OMI is likely associated with being further along in one’s drug using career,” Verdery reported in the Journal of Addictive Studies.
Verdery says additional studies are needed on the origins of drug abuse and that researchers should focus on the role that other substances play in opioid addiction. Only then can proper steps be taken to prevent abuse and addiction before they start.
"We think that understanding this mechanism as a potential pathway is worth further consideration," said Verdery. "It's not just that people were prescribed painkillers from a doctor for a legitimate reason and, if we just crack down on the doctors who are prescribing in these borderline cases we can reduce the epidemic.”
