This recent review of latest research highlights the huge immediate and longer term impact of online alcohol marketing on young people. It can result in drinking larger quantities, drinking at an earlier age, drinking more frequently and binge drinking. One study found that the effect of online alcohol advertising was almost twice as strong as that of traditional marketing. Two others highlight the informal influence of social media where young people see intoxicated friends and where drinking is perceived as the norm. Furthermore, such marketing and informal influences are largely unregulated or only self-regulated by the alcohol and advertising industries. We have covered many other studies emphasizing these problems and the particular vulnerability of young people. The research findings will be discussed online at The European Centre for Monitoring Alcohol Marketing online conference, October 31st.
