According to numerous petitions and responses regarding cannabis (marijuana) and its legalization you have stated that public health is a legitimate concern. If that truly is the case then by that premise tobacco products fall under that category as well.
"According to scientists at the National Institutes of Health- the world's largest source of drug abuse research - marijuana use is associated with addiction, respiratory disease, and cognitive impairment."
Cigarettes, cigars and other smoked tobacco products all have similar effects in terms of addiction and respiratory disease. If this truly is a concern in our government let us ban tobacco as there are 443,000 deaths per year in the US alone, which is equal to 1 in every 5 deaths while 43,000 of these alone are from secondhand smoke.
