What it is

Evidence 9/10 · thoroughly established Uneven · 1–10 by use Signals · regulator warning

Alcohol is the most widely used drug, and the evidence on its health effects has hardened over the past decade: the old idea that moderate drinking protects the heart has largely collapsed under better-designed studies, and even low intake raises the risk of several cancers. Coverage here follows guidance changes, cancer-warning labels, the rise of non-alcoholic drinks and 'sober curious' culture, treatment including GLP-1 drugs for alcohol use disorder, and the specific harms of drinking in pregnancy.

The score describes the evidence that alcohol causes harm: cancer, liver disease, injury and dependence. The once-claimed heart benefit of moderate drinking has not held up in better-designed studies.

Evidence by use or claim · 1 preclinical to 10 thoroughly established

  1. Causes cancer (mouth, throat, liver, bowel, breast)10/10 · thoroughly established

    IARC Group 1 carcinogen since 1988; dose-dependent in large cohorts.

  2. Causes liver disease and dependence10/10 · thoroughly established

    Long-settled; the leading cause of cirrhosis in most countries.

  3. No safe level of drinking7/10 · established for some uses

    WHO position; the size of the harm at low doses is still debated.

  4. Heart benefit of moderate drinking2/10 · preclinical

    Earlier observational findings have not held up in genetic and better-controlled studies.

  5. Red wine and resveratrol for longevity1/10 · preclinical

    Doses in wine are far below those used in animal studies.

  • RegulatorIn January 2025 the US Surgeon General called for cancer warnings on alcohol labels, ranking it the third-largest preventable cause of cancer after tobacco and obesity. source
  • TrialNo safe threshold has been established; the WHO's position is that no amount can be considered completely safe, and cancer risk rises measurably from about two drinks a day. source
