"Tobacco use is the single most preventable cause of disease, disability, and death in the United States. Each year, an estimated 443,000 people die prematurely from smoking or exposure to secondhand smoke, and another 8.6 million live with a serious illness caused by smoking"

cigarettes might I add have been found to have radioactive palladium
"While cigarette smoke is not an obvious source of radiation exposure, it contains small amounts of radioactive materials which smokers bring into their lungs as they inhale. The radioactive particles lodge in lung tissue and over time contribute a huge radiation dose. Radioactivity may be one of the key factors in lung cancer among smokers."

Now I'm not saying stop smoking because that would go exactly against every thing you're reading right now people should have the liberty to do what ever they want as long as It doesn't hurt anybody. if people can smoke an addictive carcinogenic ammonia laden cigg we should be allowed to consume a harmless, pain relieving, medicinal & marvelous Herb...think about it...
