David Justin Hanson (born 1941) is Professor Emeritus of Sociology at the State University of New York in Potsdam, New York. He has researched the subject of alcohol and drinking for over 30 years, beginning with his PhD dissertation investigation, and has written widely on the subject.
Professor Hanson investigates the effects of moderate alcohol consumption on health. He has amassed a large, robust body of evidence that shows the benefits of moderate drinking. Hanson is a critic of many groups that advocate the reduction of alcohol use as the solution to alcohol problems in society; he describes these groups as “neo-prohibitionist.” 
Hanson criticizes what he calls the "temperance mentality" of many groups and claims that "their tactic is to establish cultural rather than strictly legal prohibition by making alcohol beverages less socially acceptable and marginalizing those who drink, no matter how moderately."
A critic of the 21-year age limit on legal drinking in the United States, he supports the acceptance of drinking learner permits for adults under the age of 21, analogous to driving learner permits.
Hanson has published books and over 300 other publications on alcohol and maintains three websites on the subject, none of which receives any support from the alcohol industry. His research and opinions have been reported in the New York Times and other newspapers; he has been quoted in Family Circle, Health magazine, Parade and other popular publications; and textbooks in 15 fields of study report his research.
