This article is misleading, and completely irrelevant. They it says "Notably, it shows the increased danger posed by those drivers using both alcohol and drugs." This is because it is not the marijuana effecting the driver it is the alcohol's effect. Also you had no evidence for yourself, besides "49,000" studied and nothing else relevant. It "reviewed 9 studies" but sited none of them, so in which case that is irrelevant.
Bottom line this is a heaping load of bull shit.

Thanks for posting some useful information MK.
If you drive a GM car you are at increased risk of being in an accident.

* Relative risk of vehicle collision whilst under the 'acute' influence of cannabis is 1.92 whilst the relative risk of a similar vehicle accident with a blood alcohol content of 0.8 g/100 mL (the legal limit in many places) is 2.69.

* A driver with a blood alcohol concentration (BAC) of 0.10 or greater is seven times more likely to be involved in a fatal motor vehicle crash than is a driver who has not consumed alcoholic beverages, and a driver with an alcohol concentration of 0.15 or greater is about 25 times more likely.
* In a 60 km/h zone the risk of involvement in a vehicle accident with casualties increases exponentially (doubles) with each 5 km/h increase in traveling speed.

*** It is important to note that once marijuana is 'Legalized and Regulated', it will still be an offense to drive while impaired - DUI laws already apply to marijuana just like they do alcohol. The fact that being under the influence of a substance makes you a worse driver should have no bearing on its legality in general - otherwise we would be forced to hand the market in alcohol back to machine-gun tooting bootleggers.
