An Experimental Investigation Examining the Impact of Medical Association Statements about Drug Addiction on Perceptions of Criminal Culpability and Punishment

Abstract

This study examined whether public opinion on drug addiction, perceived culpability/responsibility, and punishment were impacted by statements from medical associations that drug addiction is a disease and not a choice. We utilized an experimental information provision survey distributed via Qualtrics to heads of household in South Carolina with an associated email address. The randomized treatment variable had two conditions. The first condition presented participants with a statement from several noteworthy medical associations/institutions noting that drug addiction is a disease. The second condition provided no statement (control condition). Results from our sample of over 5000 indicated that a large majority of respondents felt that individuals who have been diagnosed with a drug addiction should be fully responsible for any crimes that they commit. The presentation of official statements that addiction was a disease did not produce meaningful differences from the control group. Additionally, a large majority of respondents did not agree that addiction should relieve a defendant from punishment for drug crimes, theft crimes, or violent crimes. Here again, the presentation of official statements that addiction was a disease did not produce meaningful differences from the control groups. Finally, our results indicated that a majority of respondents viewed addiction as both a choice and disease, and the presentation of official statements that addiction was a disease did not meaningfully alter any responses.
