Ask about the difficulties and costs associated with getting pothead drivers off the roads.
I don't know any such. What have you heard?
“Ask about the difficulties and costs associated with getting pothead drivers off the roads.”
With alcohol, it is pretty much a push button operation to prosecute DUI. Present breathalyzer results, issue sentence.
For marijuana, tests indicate if you have used marijuana in recent weeks, rather than being impaired while driving. Then it is down to subjective opinion, about the condition while driving.
I guess it is like many other prescription drugs that impair drivers in that respect. Alcohol is an easy one, because of the technology and developed legal standards and procedures.
