The empirical literatures on the effects of alcohol advertising are flawed. A causal connection cannot be drawn or based on the existing body of evidence. The FTC should withdraw from this investigation and cease the request for third party evidence. Here are two references on which to base this decision: "What is Learned from Longitudinal Studies of Advertising and Youth Drinking and Smoking? A Critical Assessment", open-access at http://www.mdpi.com/1660-4601/7/3/870/ "ALCOHOL MARKETING, ADOLESCENT DRINKING AND PUBLICATION BIAS IN LONGITUDINAL STUDIES: A CRITICAL SURVEY USING META-ANALYSIS" Journal of Economic Surveys, v25(2), pp191-232.
