A large federal review of alcohol and health, commissioned by the U.S. government but never released by federal health officials, was published in June 2026 in the Journal of Studies on Alcohol and Drugs.
Even very low levels of drinking are linked to a higher risk of several cancers, the review found.
Any apparent benefit for the heart does not cancel out the overall risk.
The Alcohol Intake and Health Study began in 2023 under the federal Substance Abuse and Mental Health Services Administration, known as SAMHSA.

It was meant to help update the U.S. Dietary Guidelines.
STAT News reported that federal officials did not release the review, and that a House Oversight Committee report in January 2026 called it "irretrievably flawed."
The authors took it to a peer-reviewed journal instead.
What the researchers actually found
The team reviewed more than 7,200 peer-reviewed studies and modeled the lifetime risk of alcohol-related death and disease in the United States.

At 14 drinks per week, the upper limit of the previous Dietary Guidelines for men, the estimated risk of dying from an alcohol-caused illness or injury was 1 in 25 over a lifetime.
At about 7 drinks per week, the estimated risk was around 1 alcohol-attributable death per 1,000 people.
Drinking patterns mattered as much as weekly totals.
High per-occasion consumption raised the risk of breast cancer, cardiovascular disease and injury independently of how much someone drank across the week.

The review did note lower risks for some conditions at very low intake, including certain heart events and, for women, type 2 diabetes at up to one drink per day.
Those narrow benefits did not add up to a net protective effect at any level.
"Nearly half of Americans ages 12 and older had a drink in the past month, yet most have no clear sense of the impact on their health," said co-author Priscilla Martinez-Matyszczyk, in comments released by the Public Health Institute.
"These findings put real numbers behind everyday drinking decisions, starting at one drink a day."

7 types of cancer
Since 1988, the International Agency for Research on Cancer, part of the World Health Organization, has classified alcohol as a Group 1 carcinogen, the same tier as tobacco and asbestos.
The WHO says alcohol causes at least 7 types of cancer, affecting the mouth, throat, larynx, esophagus, liver, colon and rectum, and female breast.
It says there is no safe level of alcohol in relation to cancer risk.
The U.S. National Cancer Institute notes that even light drinkers face higher risks for some cancers.

Women who have one drink a day, it says, have a higher breast cancer risk than those who drink less than one a week.
The main mechanism is acetaldehyde, a toxic byproduct the body creates when it breaks down ethanol, which can damage DNA.
