Abstract Background and Objectives Little is known about whether people in substance use disorder (SUD) treatment are at risk for multiple‐tobacco use. We examined the factors associated with dual‐ and polytobacco use among clients in SUD treatment. Methods A cross‐sectional survey was conducted in 2019 among 562 clients ( M age = 39, 74% male) in 20 residential SUD treatment programs in California, USA. The outcomes included single‐, dual‐ (use of two products), and polytobacco use (use of three of more products). Independent variables were nicotine dependence, quitting‐related factors, blunt/spliff use, and health‐related factors. A multinomial model examined associations between the independent variables and the outcome, controlling for demographics, and time in treatment. Results Overall, 32.6%, 18.9%, and 14.0% of the sample were single‐, dual‐, and polytobacco users, respectively. Factors associated with increased odds of polytobacco use included greater nicotine dependence (adjusted odds ratio [AOR] = 1.60; 95% CI = 1.19, 2.16), ever using e‐cigarettes for quitting (AOR = 4.56; 95% CI = 2.23, 9.34), and past 30‐day use of blunt/spliff (AOR = 2.96; 95% CI = 1.48, 5.89). Factors associated with increased odds of dual use were ever using e‐cigarettes for quitting (AOR = 3.19; 95% CI = 1.79, 5.66) and reporting more mentally unhealthy days (AOR = 1.05; 95% CI = 1.02, 1.07). Conclusion and Scientific Significance This study extends the literature on tobacco use among people in SUD treatment by revealing the high prevalence of dual‐ and polytobacco use and the unique characteristics of users. The findings have implications for interventions reducing all types of tobacco use in this understudied population.
