Traffic deaths in Nevada dropped over 10% in the first year of recreational cannabis, according to data provided by the Nevada Department of Public Safety.
Between July 2016 and May 2017, 310 people died in traffic accidents in Nevada. Between July 2017 and May 2018, the first 11 months after recreational cannabis has been legalized, just 277 people died in car crashes in the state.
(DPS was unable to provide data for June 2018, and thus provided statistics from July-May to have an accurate comparison between years.)
We’ve seen that in every state or country where cannabis is getting legalized or where legalization is at least debated, one of the major concerns of recreational cannabis opponents is that traffic fatalities and DUI arrests would increase if marijuana was legalized.
In Nevada, you’re considered to be impaired from marijuana if you have more than 2 nanograms of active THC in your system.
The same thing happened in Colorado by the way.
