My argument isn't that being high isn't being impaired, because, it definitely is. So that answers your question. And I also said that I do not condone impaired driving.
I definitely believe your mind can drift when high. Does it drift more while driving high than not high? I dont know. I know for a fact I daydream while driving (completely sober) and I feel the difference is that if I am high, I feel more aware of my daydreaming. I also know that I am more cautious while high doing anything. And maybe that has something to do with illegality and being caught.
My biggest argument I suppose is that there needs to be more research done. Legalization in canada should allow that. Though there is an amount of alcohol that is allowed in your system and you can still drive. .05 in Alberta. There needs to be a limit for Cannabis.
