On March 18, 2010, the US Food and Drug Administration (FDA) announced a final rule restricting tobacco sales and promotions directed at youth. The Regulations Restricting the Sale and Distribution of Cigarettes and Smokeless Tobacco to Protect Children and Adolescents are a set of broad regulations "designed to significantly curb access to and the appeal of cigarettes and smokeless tobacco products to children and adolescents in the United States." The rule prohibits the sale of cigarettes or smokeless tobacco to people younger than 18, the sale of cigarette packages with less than 20 cigarettes, the distribution of free samples of cigarettes. The law also restricts distribution of free samples of smokeless tobacco, and prohibits tobacco brand name sponsorship of any athletic, musical or other social or cultural events. The rule went into effect on June 22, 2010.
