WASHINGTON, Nov. 10 (Xinhua) -- The U.S. Food and Drug Administration (FDA) has sent warning letters to more than 1,200 retailers, the majority of which respond to violations relating to selling tobacco to minors, as part of its ongoing effort to reduce tobacco use among children, the agency announced Thursday in a statement.The FDA said that while most retail establishments have been found to be in compliance with the law, some retailers are still selling cigarettes and smokeless tobacco to minors. Warning letters may be followed by civil money penalties if retailers continue to violate the law."It should worry every parent that 20 percent of U.S. high school students smoke cigarettes," said FDA Commissioner Margaret Hamburg in a statement. "President Obama and the FDA are committed to preventing children from smoking. For many young people, that first cigarette or use of smokeless tobacco will lead to a lifetime of addiction, and for many, serious disease. More than 80 percent of adult smokers begin smoking before 18 years of age. Retailers are vital partners in the FDA's efforts to prevent tobacco use among kids."Obama signed the Family Smoking Prevention and Tobacco Control Act that gives the FDA authority to regulate tobacco products to prevent use by minors and reduce the impact on public health. One of the law's provisions permits the FDA to contract with states and territories to conduct compliance check inspections of tobacco retailers. In 2011, the FDA awarded compliance contracts totaling more than 24 million U.S. dollars to 38 states.The FDA also began inspecting U.S. tobacco product manufacturers in October 2011. This is the first time tobacco product manufacturing facilities have ever been inspected by a federal public health agency.

But, they found, it was only those in the highest quartile of chocolate consumption who had a significant drop in stroke risk.The researchers explained that cocoa has flavonoids - powerful antioxidants that can suppress LDL, low-density lipoprotein, that can cause stroke and other cardiovascular diseases.
