Tobacco takes a physical, emotional and financial toll on everyone it touches. From heart and respiratory diseases to more than a dozen types of cancer, the negative health effects linked to tobacco use are staggering. Cigarettes will kill half of all regular users. And they are more deadly to regular smokers today than they were in 1964 when the U.S. Surgeon General released a landmark study on smoking and health effects. But the harms go beyond individual smokers. The environment, international economy and the public’s safety are all affected by tobacco.
