Every day some 28 fatalities will be caused by impaired driving:
- As the number of states approve adult-use cannabis consumption, impairment goes up
- 40% of traffic crashes are alcohol-related; but 9-12% of crashes are cannabis-related

- CMMI is dedicated to connecting the gap between theory and reality-- to Save Lives!
Cannabis impairment is most critical in the first 2-3 hours.
