The Denver Post has reported that the incoming Legislature will likely consider a proposal created by the Colorado Commission on Criminal and Juvenile Justice, limiting the intake of marijuana before driving to 5 nanograms per milliliter of blood.
We've e-mailed a likely sponsor of the bill, Boulder Democrat Rep. Claire Levy, for comment on what the roadside testing would be, and how it would differentiate at what time marijuana was introduced into the body; we'll update this blog with any response.
In the meantime, here's the Post:
Sean McAllister, a lawyer who serves on the commission's drug policy subgroup, said the research doesn't take into account the tolerance level of frequent users. He said he worries that the proposal could unfairly affect medical-marijuana patients, who may be able to have higher THC levels without impairment.
But, he said, he agrees something needs to be done, and he said he advises patients to wait at least four hours after using marijuana before driving.
"No responsible advocate of legalization believes that people should be driving high," McAllister said.
