Alcohol and tobacco bring death and misery to people.
How many people die from Alcohol and how many people die from Tobacco?
According to the CDC (http://wonder.cdc.gov/ucd-icd10.html) in 2011, 2,284 Americans died from the direct cause of "poisoning by and exposure to alcohol."
Your number is way too small. You left out the people killed by drunk drivers.
You never defined "die from alcohol." I'm on board with including those people.
You know, the innocent people which Libertarian philosophy says not to harm.
I'm not sure what you're saying here. Are you claiming that "Libertarian philosophy" regards drunk drivers as "innocent people not to harm"? Or if by "innocent people" you meant the victims, then yes, they should not have been harmed, and they were wronged by the drunk drivers - but they were wronged by the legality of alcohol no more than by the legality of cars.
And let's not forget the subject of this thread: "Since marijuana legalization, highway fatalities in Colorado are at near-historic lows."
Fatal crashes involving drivers who recently used marijuana doubled in Washington after the state legalized the drug,” the AAA reports.
“The significant increase in fatal crashes involving marijuana is alarming,” said Peter Kissinger, AAA Foundation for Traffic Safety CEO, adding that “Washington serves as an eye-opening case study for what other states may experience with road safety after legalizing the drug.”
