Thanks for the comment! Impairment is the big question surrounding the enforcement of driving under the impairment of cannabis. It varies much more than alcohol based on BMI, age, and use history. Here are a few good resources for understanding cannabis impairment and how it compares to alcohol. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2722956/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2722956/ https://mass-cannabis-control.com/wp-content/uploads/2019/01/FINAL-RR1-PS1-Cannabis-Impaired-Driving_2019-1-18.pdf https://mass-cannabis-control.com/wp-content/uploads/2019/01... One of the most prolific researchers in this space is Marilyn Huestis. Anything by her is really good.
