• Controlled drinking is framed as a practical harm-reduction strategy, with experimental and longitudinal data suggesting abstinence is not the sole path for many alcohol users; protocols for establishing controlled drinking and outcomes are described across multiple studies [12] [4] [13] [6] [14] [20].

• Public health policy and epidemiology frame harm reduction through government control measures, population-level prevention, and drinking-problem prevention programs, linking policy levers to health outcomes [10] [18] [17].

• Behavioral interventions emphasize self-control training, bibliotherapy, decision-making, and structured programs delivered in individual, group, and preventive settings to reduce problem drinking [7] [9] [15] [2] [12].

• Cross-substance harm reduction integrates alcohol interventions with opioid addiction treatment, examining abstinence and controlled drinking in methadone-maintained populations and pilot multi-substance prevention [8] [11] [16] [5].

• Loss-of-control theory and relapse-prevention work anchors the field, using experimental analogues to define control limits and to shape drinking-management strategies [1] [19] [13] [12].
