You’ll have to try again.
Alcohol is not the only drug included within DUI, DWI, and BUI, and BWI. For 2009 the CDC reports, ‘...drugs other than alcohol (e.g., marijuana and cocaine) are involved in about 18% of motor vehicle driver deaths. These other drugs are often used in combination with alcohol’ Almost 1 in 5 DEATHS that year, not a number we should enable becoming larger wouldn’t you say?
Assuming such DWI crimes were (and perhaps in some jurisdictions are) exclusive to alcohol - are you saying that marijuana users never drive under the influence of POT? Or that the effect of being stoned has no impairing effect on a drivers reaction time, decision making, etc.? Don’t believe there’s a difference driving with a beer buzz or a pot buzz - the driver becomes a danger to himself and others.
As to your claimed number of marijuana overdoses being equal to zero, I don’t have access to your source for this statistic (please send unless it was manufactured for argument sake). Taking the assumption the statistic is correct, are you also arguing there’s no health risks? Or, that use, infrequent or abusive, will never lead to a disabling or fatal condition?

Shouldn't intrastate drug policies, such as legalization and regulation, be decided by states rather than fedgov under authority of the 10th Amendment?
