This is the first sentence of the bill:

"The bill allows a person who drives with a tetrahydrocannabinols
(THC) blood content of 5 nanograms or more to be charged with DUI per
se."

Considering the information about THC and driving out there, and the lack of a problem with drivers using cannabis, this surprises me.

How did they determine the 5 nanogram benchmark?
