Becoming tobacco-free: Changes in staff and patient attitudes and incident reports in a large academic mental health and addictions hospital.

Background And Objective: Complete tobacco bans in mental health facilities are thought to have the potential for adverse consequences. We evaluated staff and patient attitudes and adverse events associated with implementing Canada's largest, multi-site academic psychiatric hospital tobacco ban.

Methods: A total of 1,173 staff and 422 patients completed an anonymous attitudes survey at prior to implementation (baseline), and 4-6 months and 10-12 months post-implementation.
