35 years of research reports about driving on cannabis / marijuana.

  For the public health and safety, these  Marijuana driving research materials are presented in order to educate legislators and the public about driving safety.  Please remember that a lot of these studies have been biased over the years. The largest study to date, completed by The National Highway and Traffic Safety Administration  says that marijuana poses no increased risk of accident or crash. https://www.nhtsa.gov/sites/nhtsa.dot.gov/files/documents/812440-marijuana-impaired-driving-report-to-congress.pdf

When the odds ratios were adjusted for demographic variable of age, gender, and race/ethnicity the significant increased risk of crash involvement associated with THC disappeared. The adjusted odds ratio for THC positive drivers was 1.05 (95% Confidence Limit of 0.86 – 1.27). This adjusted odds ratio was not statistically significant. A final adjustment was made for the presence of alcohol. When both demographic variables and the presence of alcohol were taken into account, the odds ratio for THC declined further to 1.00 (95% Confidence Limit of 0.83 – 1.22). This means there was no increased risk of crash involvement found over alcohol or drug free drivers. As was described above, there was no difference in crash risk for marijuana-positive drivers who were also positive for alcohol than for marijuana-positive drivers with no alcohol, beyond the risk attributable to alcohol. http://www.nhtsa.gov/staticfiles/nti/pdf/812117-Drug_and_Alcohol_Crash_Risk.pdf

NOTE: Many reports will say that drivers have marijuana in the blood, yes, of course, because marijuana is detectable in your blood for months.
