Has any state in the union set a legal limit for THC in the bloodstream of drivers, anyone know?
Until that’s done, seems to me like we’re putting cart before the horse.
first you need an affordable way to measure it on the side of the road.
https://www.ghsa.org/state-laws/issues/drug%20impaired%20driving:
18 states have zero tolerance or non-zero per se laws for marijuana.
9 states have zero tolerance for THC or a metabolite.
3 states have zero tolerance for THC but no restriction on metabolites.
5 states have specific per se limits for THC
1 state (Colorado) has a reasonable inference law for THC
In Ventura California my son was just on a jury for that specific thing.
The guy was driving while under the influence of marijuana.
They found him not guilty because there are no limits in the law for marijuana.
