Prospective Associations Between Tobacco Product Use and Mental Health and Substance Use Problems Among U.S. Adolescents and Adults

Intervening when mental health problems are seen among adolescents may minimize tobacco uptake. Likewise, preventing tobacco use may curtail substance use problems, and treatment of substance use problems may reduce tobacco use. Findings highlight the critical need to incorporate the bidirectionality among mental health, tobacco use, and substance use into prevention and treatment efforts.
