Where I am going with this is that alcohol is out of your system relatively quickly, thereby making tests for DUI and investigations relatively accurate. Given the way marijuana stays in the system tho, and the heavy user/light user argument, how would you be able to tell if someone was stoned out of their mind causing a traffic accident or just a recovering heavy user that hasn't had any in weeks?

And while marijuana itself might not kill people, here are a couple of articles that cite it as a possible contributing factor in fatalities:

While I agree that drugs being illegal is akin to the crime wave and resource waste that went along with Prohibition, I'm more concerned about "the law of unintended consequences" if everything became legal tomorrow.

I'm open to the opinions of those more qualified than me on this (LEO's and Medics in particular)

Piss tests/blood draws/breathalysers are meant as a secondary level of confirmation of what the LEO already observed, not the end all, be all of if someone is intoxicated. A DUI arrest can be made without any of those. However, having them is just that much more evidence (in conjunction with evidence to make the stop, results of the field sobriety tests).
