On December 20, 2019, Congress raised the federal MLSA for tobacco products from 18 to 21 years. This legislation, known as Tobacco 21 or T21, became effective immediately, and it is now illegal for a retailer to sell any tobacco product – including cigarettes, cigars, and e-cigarettes – to anyone younger than 21 years.8The new federal MLSA applies to all retail establishments and people with no exceptions; it applies to retailers in all states, DC, all US territories, and on tribal lands. There is no exemption for active duty military personnel or military veterans between the ages of 18 and 20 years,8as had previously existed in some states.
