Harm to what? What is this chart and study basing itself on? Harm to self? Harm to others? Long term harm? short term harms?

People have passed out and died from ODing on cocaine, LSD and Heroine. You think thats less harmful than a 20-30+ year death sentence tobacco is? I don't get the point of this. Perhaps if everything is reclassified and the laws are loosened up a bit, do you think people driving high will do it less, or more?

I guarantee you if I drove drunk I'd hit something or someone. I guarantee you if I drove stoned off pot I'd hit something or someone.

Does this study take that into account?

But can you take into account not looking both ways on before crossing the road when you've drunk a bit too much?

What you have stated are variables, and the whole idea of a scientific study is to eliminate as many variables as possible.
