You want legal THC? How about a zero tolerance law for driving: no behind the wheel if under the toke - 24 hour ban?
It works for pilots and liquer. The liquer is still legal.

Driving is not a right.
It would be a drastic improvement over the status quo. (Needs to be a state by state decision under the Constitution, of course.)
