Essential cbd The original bill proposed removing THC from the list of restricted controlled substances as applicable to the operation of a motor vehicle, a regulation aligned with most other states. If a driver pulled over for a traffic violation has consumed a product made with trace amounts of THC, such as CBD, they would not be charged with operating while intoxicated. The bill would also make an exception for the trace amounts of THC contained in hemp in the state’s list of controlled substances. Wisconsin remains one of 12 states with a zero-tolerance THC law, per the National Conference of State Legislatures. As of this writing, Wisconsin’s state Senate health committee had voted unanimously to pass the amended hemp bill along to the full state Senate on August 20, 2019. Taking law enforcement’s concerns into consideration, the amended bill puts into law the current practice of allowing a driver to have a trace amount of THC in their blood, a level well below what is intoxicating. Six other states have similar laws.
