Right and high blood pressure kills 3.37 million per year. Does that call for the removal of all potentially dangerous food ever? No. People are sentient and cognitive beings that can make their own choices. People die every day from a variety of reasons and I don't really care either way. 

The biggest killer of humans is ultimately their own ignorance and stupidity.  If you get an intelligent person high and a stupid person drunk of course the stupid person is going to make worse choices.
