Understanding this genetic basis can open up potential avenues for targeted interventions and treatments, which could ultimately influence the lifespan of those struggling with alcoholism. Specifically, the genes that contribute the most to the risk for alcoholism and alcohol consumption are alcohol dehydrogenase 1B (ADH1B) and aldehyde dehydrogenase 2 (ALDH2). The variants ADH1B48His and ADH1B370Cys metabolize ethanol at higher rates than ADH1B1, and ALDH2504K has a protective effect against alcohol…
