An Examination of Substance Use Disorder Type, Legal Status of Drug, and Treatment Outcomes

Abstract

Background

From the anti-tobacco and anti-marijuana campaigns of the twentieth century to the current controversies surrounding vaporizer use and the opioid epidemic, substances and substance use have been at the forefront of cultural, public health, and legal debates for decades. This work explores treatment outcomes among those with substance use disorders (SUD) by 1) comparing legal, semi-legal, and illegal drug types and their impact on treatment outcomes and 2) evaluating the extent that there exist discrepancies between those who need and those who receive treatment. Methods: Binary logistic regression models were employed with data from the 2018 National Survey on Drug Use and Health (NSDUH) to examine the relationship between type of SUD and treatment outcomes. Results: Results indicate that those with SUD to illegal drugs were generally more likely to report a need and receive treatment than those with SUD to a legal drug (alcohol use disorder). Those with SUD to some types of illegal drugs did not report more need, but in some cases reported more treatment. Additionally, analyses indicated that across treatment outcomes, those with marijuana use disorder (semi-legal drug) were less likely to report needing or receiving treatment than those with alcohol use disorder. Conclusions: This research examined the role of drugs’ legal status and type of SUD in need for treatment and treatment received. The discrepancy between needing and receiving treatment suggests those with some types of SUDs may be pushed into treatment at higher rates based on the stigma surrounding the substance they use.
