Estimates from the National Survey on Drug Use and Health (Substance Abuse and Mental Health Services Administration [SAMHSA], 2019) suggest 3.6% of persons aged 12 and older misused prescription pain relievers in the past year and 0.3% used heroin. However, research suggests that most individuals drastically overestimate rates of substance use and misuse. Those who overestimate substance misuse are often more likely to misuse substances themselves (Kilmer et al., 2015; McCabe, 2008). Purpose: To compare perceived versus actual rates of prescription pain reliever misuse and heroin use among a statewide sample of adults and identify correlates of these differences. Methods: Participants (N = 689) recruited through social media estimated rates of prescription pain reliever misuse and heroin use. Participants also indicated whether they engaged in pain reliever misuse or heroin use, and whether they knew anyone who misused prescription pain medications or heroin. Results: Almost all participants (98.11%) overestimated the prevalence of prescription pain reliever misuse (mean estimate = 41.25%) and heroin use (99.71%, mean estimate =25.46%). Women and African Americans were more likely to overestimate prescription pain reliever misuse and heroin use. Knowing someone who misused prescription pain relievers was significantly associated with overestimating prescription pain reliever misuse. Personal use was not associated with overestimating prevalence of either substance. Conclusions: Adults consistently overestimate rates of prescription pain reliever misuse and heroin use. Overestimation may increase normative perceptions of substance use and ultimately lead to increased substance use. Social-norms based education and interventions may be particularly important among groups that are more likely to overestimate use.
