Attorneys general from 24 states have asked the U.S. Federal Trade Commission to do more to shield teenagers from alcohol advertising. A letter, written by Utah Attorney General Mark Shurtleff and signed by colleagues from 23 other states, proposes a three-step plan to regulate teens’ exposure to alcohol ads, the Deseret News reports.

The letter proposes that data collection from alcohol advertisers about how they advertise, sell and market alcohol be ongoing instead of intermittent. The attorneys general also recommend that advertising be barred when more than 15 percent of the audience is between the ages of 12 and 20, and that data about alcohol advertising be collected for digital and social media marketing, such as blogs and corporate-sponsored social media sites.

The letter was signed by the attorneys general in Arizona, Connecticut, Delaware, Guam, Hawaii, Idaho, Illinois, Iowa, Maryland, Massachusetts, Mississippi, Nevada, New Hampshire, New Mexico, New York, Oklahoma, Oregon, Rhode Island, South Carolina, Tennessee, Utah, Vermont, Washington and Wyoming.
