Featuring chapters written by scholars and clinicians who are also members of the LGBTQ and ally communities, this text addresses a significant gap in addiction counseling knowledge for LGBTQ clients with substance use disorders (SUD ). The book integrates LGBTQ affirmative counseling principles with evidence-based addiction counseling to cultivate ethical, culturally responsive treatment practices. It includes reflections from LGBTQ individuals who have lived experiences with the continuum of substance use, process addictions, and recovery.
