Alcohol is killing Americans at a rate not seen in at least 35 years, according to new federal data. Last year, more than 30,700 Americans died from alcohol-induced causes, including alcohol poisoning and cirrhosis.

In 2014, there were 9.6 deaths from these alcohol-induced causes per 100,000 people, an increase of 37 percent since 2002.

This tally of alcohol-induced fatalities excludes deaths from drunk driving, other accidents and homicides committed under the influence of alcohol. If those numbers were included the annual toll of deaths directly or indirectly caused by alcohol would be closer to 90,000, according to the Centers for Disease Control and Prevention.

In 2014, more people died from alcohol-induced causes (30,722) than from overdoses of prescription painkillers and heroin combined (28,647), according to the CDC.

Philip J. Cook, a Duke University professor who studies alcohol consumption patterns and their effects, notes that per-capita alcohol consumption has been increasing since the late 1990s.

“Since the prevalence of heavy drinking tends to follow closely with per capita consumption, it is likely that one explanation for the growth in alcohol-related deaths is that more people are drinking more,” he wrote in an email.

The number of American adults who drink at least monthly rose by a small but significant amount between 2002 and 2014 – from 54.9 percent to 56.9 percent – according to data from the Substance Abuse and Mental Health Services Administration. The change has been especially pronounced among women. The percent of women drinking monthly or more rose from 47.9 in 2002 to 51.9 in 2014. And the percentage of women reporting binge drinking – defined as five or more drinks on at least one occasion – rose from 15.7 to 17.4 percent over the same period.

The heaviest drinkers are at the greatest risk for alcohol-induced causes of mortality. And some drinkers consume plenty of alcohol indeed. Prior research by Cook indicates that the top 10 percent of American adults consume the lion’s share of alcohol in this country – close to 74 drinks a week on average.

For people who drink less, alcohol’s effects on health are less clear-cut. A large body of research seems to indicate that moderate alcohol consumption – around a drink or two a day – is associated with decreased risk of mortality.
