Serious questions: What are the actual dangers of driving while high? If we can somehow normalize the amounts, which is more dangerous to driving: Smoking weed or drinking alcohol?
(I expect it is higher, but that seems hard to produce meaningful data. Self reported? Subject to a blood test? A piss test that detects 2 months use?)
Alcohol is probably worse.
Allowing people to research cannabis would let us know what the risk is.
