Montana's House Judiciary Committee heard testimony on Representative Ken Peterson’s bill which aims to make it illegal to drive while on any dangerous drugs "per se." House Bill 33 also includes metabolite, or any molecule left in the body, yet excludes prescription medication if taken under doctors orders. "This bill makes sure you can’t drive while impaired under the influence of drugs and I don’t think this bill requires any showing of impairment, it deems somebody to be on the wrong side of the law merely for having a few molecules of certain substances in their blood," said medical marijuana patient Barbara Trego.
