This document discusses two controversial issues regarding substance use disorders and asks for arguments and evidence from attached sources on each issue. The first issue is whether individuals with substance use disorders can moderate their use through treatment instead of abstinence. The second issue is whether a substance use disorder should be considered a disease. References and evidence to support arguments on both issues must come from three specific sources: two journal articles on controlled drinking approaches to alcoholism treatment and a chapter on substance use disorders from an abnormal psychology textbook.
