She is known for her research on how marijuana use affects driving and how exposure to parents’ marijuana use affects the developing fetus, breast-feeding newborns, and young children, as well as the new psychoactive substances. Key Points US is not prepared for driving with marijuana on board. Huge issue and huge problem. In occasional users, 74% of THC comes out of the body in 30 minutes, 90% in 1.4 hours. Average time to get drivers’ blood drawn is 1.4 to 4 hours. Many states have zero tolerance levels such as 1 or 2 nanograms per milliliter. Establish impairment first, then take the biological sample. A-Ride Program (NHTSA) trains every police officer to do the field sobriety test. Also can establish impairment via witnesses.
