Abstract

Drug overdose deaths in the United States increasingly include the use of multiple drugs, known as polysubstance use. These include opioids, cocaine, methamphetamine, tranquilizers, and sedatives. Polysubstance use is considered high risk because it can cause dangerous synergistic effects and result in the ingestion of higher amounts of drugs. This brief summarizes findings from a study that used data from the National Survey on Drug Use and Health on U.S. adults from 2002 through 2019 to examine gender and marital status differences in high-risk polysubstance use among U.S. adults ages 18 and older. The authors find that polysubstance use is higher among men and marriage was more protective against polysubstance use for men than women.
