SESTA/FOSTA Examination of Secondary Effects for Sex Workers Study Act or the SAFE SEX Workers Study Act This bill requires the Department of Health and Human Services to study the impacts of the reduction in access to client-screening, information-sharing, and harm-reduction websites resulting from the Allow States and Victims to Fight Online Sex Trafficking Act of 2017 on individuals engaged in adult, consensual sex work. The study must utilize community-based nonprofits to conduct surveys and interviews of sex workers to collect information about (1) experiences of violence from clients; (2) interactions with law enforcement; (3) experiences with exploitation; and (4) the impact on housing stability and mental health, among other effects.
