Smoking is the leading cause of preventable death in the United States. Smoking increases the risk of heart attack and stroke, respiratory problems, lung and other types of cancer. Despite the fact that these deaths are 100 percent preventable, researchers are predicting that the global annual deaths from smoking will double to 10 million by 2020.  An increase in smoking deaths is troubling enough, however that does not include deaths related to second hand smoke inhalation and the rising trend of smoking among young females. In an international survey of young females, ages 13-15, nine percent of young girls admitted to habitually using tobacco products. Dr Charles Warren, of the Centers for Disease Control and Prevention (CDC) in Atlanta, Georgia, is calling for an increased effort to implement non smoking programs geared towards young adult, especially females. "The high use of tobacco among young girls is the worst news we could have," said Warren. "It is an indication that big change is occurring, which is very different from what we see from adult females."
