SOOOOO don't get mad but: there is plenty of evidence that driving after smoking weed causes various sorts of impairment but the evidence that it causes DANGEROUS impairment is actually pretty skimpy, and it's almost certainly vastly safer than driving drunk.
We used to have a joke about this.
A drunk driver blasts through a stop sign. A stoned driver stops at the stop sign and waits for it to turn green. Both of these are wrong, but one is more dangerous than the other.
Not endorsing either, but they do differ.
