Increased use of psychoactive substances among Brazilian health care professionals during the COVID-19 pandemic.

This study aimed to estimate the prevalence of increased psychoactive substance use (PSU) and associated factors among health care professionals. A cross-sectional and analytical study with 12,086 Brazilian health professionals was undertaken. An online questionnaire was used to gather data concerning sociodemographic factors, increased consumption of alcoholic beverages, tobacco, and hypnotics or sedatives during the COVID-19 pandemic. The prevalence of tobacco, alcoholic beverages, and hypnotic or sedative consumption were 17.8 %, 69.0 % and 17.1 %, respectively. Regression analyses indicated that having no religion and social isolation were associated with increased PASU during the pandemic. COVID-19 pandemic stressors may increase PASU, and increased PASU may increase the risk of substance use disorders and substance use-related chronic diseases, such as cancer.
