here's some proof about the driving:
"A number of driving simulator studies have shown that marijuana does not produce the kind of psycho-motor impairment evident with modest doses of alcohol. In fact, in a recent NHTSA study, the only statistically significant outcome associated with marijuana was that drivers drove more slowly."
and in another recent study in heavy urban traffic "Drivers under the influence of marijuana also tended to decrease their speed and approach other cars more cautiously. "
this is quoted off a web site.. NHTSA is the U.S. National Highway Traffic Safety Administration.
