According to the CDC (http://www.cdc.gov/tobacco/data_statistics/fact_sheets/health_effects/tobacco_related_mortality/) there are "More than 480,000 deaths annually " related to cigarettes and (http://www.cdc.gov/alcohol/fact-sheets/alcohol-use.htm) "approximately 88,000 deaths attributable to excessive alcohol use each year in the United States"
In 2011, the CDC says (http://www.cdc.gov/homeandrecreationalsafety/overdose/facts.html) "33,071 (80%) of the 41,340 drug overdose deaths in the United States were unintentional"
So ciggs+alcohol deaths ~ 570,000 deaths per year
Accidental drug overdose ~ 33,000 deaths per year
Now which should be legal and/or a greater concern to society at large? Which likey have a greater economic cost to society? Which has a greater overall impact?
I'm not saying hard drugs aren't bad, but perhaps we should concentrate on what is causing the most damage first.
