United States Surgeon General Vivek Murthy wants Americans to believe there’s no safe amount of alcohol consumption. His recent advisory calling for cancer warning labels on alcohol bottles follows a familiar pattern in American public health messaging: take a complex scientific issue, reduce it to its most frightening elements, and propose heavy-handed interventions that go well beyond what the evidence suggests.

Murthy’s timing is particularly interesting. His dramatic proclamation arrived just weeks after the National Academies of Sciences released a comprehensive review showing moderate alcohol consumption is actually associated with lower all-cause mortality than no alcohol consumption at all. The disconnect between these positions offers a window into how public health institutions sometimes shape research interpretations to justify interventions, much like during various phases of the disorganised and at times ham-fisted Covid-19 response.

The National Academies’ report tells a more nuanced story than Murthy’s blanket condemnation suggests. Specifically, it found that moderate drinking is linked to lower cardiovascular mortality and reduced risk of heart attacks and nonfatal strokes. While they did identify some increased breast cancer risk with moderate consumption, the overall picture is complex enough that it hardly justifies warning labels equating any amount of alcohol with cancer.

Perhaps most tellingly, heavy drinkers — who make up just 7.2% of alcohol consumers — account for roughly 75% of alcohol-related cancers. The risk ratios for light drinkers are minimal and often offset by other lifestyle factors. Yet Murthy’s advisory makes no distinction between someone who enjoys an occasional glass of wine with dinner and someone who drinks heavily every day.

The timing of this crusade raises questions about institutional motivations. Murthy’s second non-consecutive term (he has served under both Obama and Biden) ends on 20 January and his dramatic stance suggests possible political considerations. Public health bodies have a documented tendency to pursue increasingly aggressive interventions over time. We need look no further than the government’s decades-long campaign against the tobacco industry. It started with warning labels before progressing to advertising restrictions, steep taxes, and eventually outright bans in many spaces.

The National Academies’ methodology highlights just how carefully such health data needs to be handled. They specifically excluded studies that combined never-drinkers with former drinkers to avoid “abstainer bias” — the sort of rigorous distinction absent from the Surgeon General’s sweeping demand for a warning label. They also focused on research from 2010 onwards, ensuring their conclusions reflected the most current understanding rather than outdated assumptions.

The alcohol-cancer relationship deserves serious study and appropriate public health responses. But those responses should be proportional to the actual evidence, not driven by institutional momentum or political expediency. Warning labels that treat all alcohol consumption as equally risky and mirror similar labels on well-tested nicotine products fail this basic test of scientific accuracy and risk communication.

Murthy’s crusade says more about America’s public health bureaucracy than it does about alcohol’s health effects. Like many questionable institutional proclamations before it, it demonstrates how readily nuanced scientific findings can be transformed into simplistic messages that justify expanding regulatory reach. It also offers new ways for elite-led public health nonprofits to raise and then allocate their funds. The question isn’t whether alcohol carries health risks — it clearly does, as far as operating a motor vehicle goes — but whether those risks are being accurately communicated in service of sound public policy.

This reductionist tendency does a disservice to both science and public health messaging. When institutions consistently overstate risks or ignore countervailing evidence, they erode public trust, trust they’ll need when confronting genuine health emergencies that do require dramatic interventions.
