Did you have an opinion on that article?
Copy and pastes are viewed as spam in my eyes
Anyway from the top half of the article I would completely agree..
A field sobriety test is the only conclusive evidence that one is "too impaired" to drive.
If that study is the same study from another forum I visit, the study included people who smoked pot days ago and over a year ago, so there percents will be off by a lot. Not saying driving while stoned is bad but you shouldn't like any other drug.
Honestly it depends on how stoned you are. I can drive after 4 bong rips no problem, but after 6 bong rips and a pinch of hash, hell no.
