Back to booze vs. pot. How do the effects of these two drugs stack up against specific health and public safety factors?
Alcohol-related traffic accidents claim approximately 14,000 lives each year [in the USA], down significantly from 20 or 30 years ago (attributed to improved education and enforcement). Figures for THC-related traffic fatalities are elusive, especially since alcohol is almost always present in the blood as well, and since the numbers of "marijuana-only" traffic fatalities are so small. But evidence from studies, including laboratory simulations, feeds the stereotype that those under the influence of canniboids tend to (1) be more aware of their impaired psychomotor skills, and (2) drive well below the speed limit. Those under the influence of alcohol are much more likely to be clueless or defiant about their condition, and to speed up and drive recklessly.

Over the past four years I've asked police officers throughout the U.S. (and in Canada) two questions. When's the last time you had to fight someone under the influence of marijuana? (I'm talking marijuana only, not pot plus a six-pack or a fifth of tequila.) My colleagues pause, they reflect. Their eyes widen as they realize that in their five or fifteen or thirty years on the job they have never had to fight a marijuana user. I then ask: When's the last time you had to fight a drunk? They look at their watches.
