WHO release: A Working Group of international experts was convened by the International Agency for Research on Cancer (IARC) to review and assess all available evidence on the effectiveness of selected alcohol policies in reducing consumption of alcoholic beverages at the population level. Although alcoholic beverages were classified as carcinogenic to humans (Group 1) several decades ago, no such evaluations had been performed so far. The Special Report published in The New England Journal of Medicine summarizes the studies reviewed and presents the conclusions of the Working Group. The detailed assessments will be published as Volume 20B of the IARC Handbooks of Cancer Prevention.
