I feel certain that most non-intoxicated people can understand that when someone says that "no one has ever died from smoking marijuana," the person is referring to the direct effects of the drug.
As far as driving while intoxicated, the evidence cited for item #4 indicates that "it doesn’t appear that
the roads are any more dangerous than they were before prohibition was lifted in legal states." Do you know of any evidence to the contrary?
In fact, I would definitely prefer to meet someone on the road who is "intoxicated" from smoking marijuana than intoxicated from drinking alcohol. And legalization of marijuana may indeed lessen the incidence of driving while intoxicated on alcohol.
Provide your citations. I wasn't intending to provide a forum for people to express irrational fears and anger.
