As usual, you're not defending your absolute statement, nor answering the question. In the U.S., 100M a year die from fentanyl, and it's illegal in most jurisdictions. Auto deaths bottomed out around 35M a year, and have ballooned to 47M a year since the advent of texting and, lesser so, the relaxation of drug laws.
I never asked what was less or more, just that I think texting and/or high drivers shouldn't be on the road, just like drunks. It's not about what's worst. None of them should be on the road.
Pot smokers have a knee jerk defense for any discussion or findings of the negative aspects of smoking. The positive benefits are murky, and the damage is becoming more clear. They are the tobacco smokers, and the industries standing to benefit, of the fifties and sixties.
