Washington ? Even before its release, a report on teen drinking has drawn charges of bias from the $110 billion-a-year alcohol industry, an intense lobbying campaign and congressional warnings not to interfere with the industry’s marketing.

The pending report, by the National Academy of Sciences’ Institute of Medicine, will assess current efforts to control underage drinking and propose new ones.

It is expected to weigh, among other things, what additional taxes on alcohol and restrictions on advertising and marketing might do to teen drinking.

Studies indicate that underage drinking, especially binge drinking, is a persistent problem, and that illegal consumption of liquor may account for between 10 percent and 20 percent of total U.S. sales.

Activists fighting underage drinking hope — and some in the alcohol industry worry — that the report will spur aggressive anti-alcohol initiatives similar to anti-smoking campaigns.

The report, originally due out last month, is being reviewed by independent outside experts. Release is now expected in August or September.

Some industry groups say the NAS panel dismissed their input and ignored their members’ programs to reduce teen drinking.

“Our industry probably spends tens of millions of dollars fighting underage drinking. We really try to get parents and educators involved. Those are proven methods that have worked,” said Michelle Semones, a spokesperson for the National Beer Wholesalers Assn.

The NAS report, she said, is focused instead on unproven tactics like raising taxes on alcohol.

The Beer Wholesalers — prominent in conservative Republican circles since the party’s takeover of the House of Representatives in 1994 — recently sponsored a letter to National Academy President Dr. Bruce Alberts signed by 134 lawmakers. The letter warned them against using the report to recommend “changes intended to adversely affect the beverage industry.”
