Tobacco use and interest in smoking cessation among people who inject drugs in a medically supervised injecting centre (MSIC).

Introduction: Tobacco smoking is a leading cause of preventable death. Although, smoking rates in the general population are decreasing (15.8%), the rate of tobacco smoking among persons who inject drugs (PWID) remains high, ranging from 71% to 96%. Understanding PWID tobacco smoking and interest in quitting is paramount to being able to address their tobacco use and reduce tobacco-related harms. This study sought to examine smokingrelated behaviors and interest in smoking cessation among PWID engaged in a MSIC.
