“We were surprised at the number of people who transitioned to heroin. ” - Dr. Robert Carlson, Wright State University

Racial divide
The study also saw a difference in race among those who eventually turned to heroin. Despite roughly half the participants being African-American or Hispanic, all of the individuals who ultimately used heroin were white. Although the study could not determine the reasons behind such a strong racial divide, Dr. Carlson suggests that social networks, generational use and other circumstances could be signi cant factors. National data shows the heroin epidemic has increasingly hit white males the hardest. The Centers for Disease Control estimates that between 2002 and 2013, heroin use among non-Hispanic whites increased 114 percent.
Age is just a number
The new NIDA-funded study targeted 18- to 23-year-olds because they are arguably at the highest risk for substance abuse. The study did not look at other age groups. But when considering the factors that may move a person from prescription opioids to heroin, Dr. Carlson believes age is just a number. “I wouldn’t think the risk factors for transition to heroin would be much different regardless of age group,” Dr. Carlson says. While the risk factors may be the same across age groups, the most deadly effects of heroin use are not. Research has shown that those most at risk of a heroin-related overdose fall in the 25 to 44 age range.
Targeted approach
It’s important to keep in mind that the vast majority of prescription opioid users will not move on to heroin. And signi cant research is still needed to determine the social, environmental and biological factors that contribute to a person transitioning to heroin. But Dr. Carlson says he’s encouraged by the progress being made and believes the groundwork has been laid to develop effective treatment and intervention programs. “The really exciting thing to come out of this is it really gives us a rm foundation of some variables that could be targeted to prevent transition to heroin and transition to dependence,” Dr. Carlson says.
