Nevada traffic deaths show 10 percent decrease since marijuana was legalized. Can this be directly attributed to marijuana? Probably not. Still, watching these numbers should tell us something useful, as marijuana is a substitute for alcohol and that alone should shrink alcohol related traffic crashes.
Nevada traffic deaths dropped 10 percent in first year of recreational marijuanaby Ben MargiottRENO, Nev. (News 4 & Fox 11) —
Traffic deaths in Nevada dropped over 10 percent in the first year of recreational marijuana, according to data provided by the Nevada Department of Public Safety.
310 people died in traffic accidents in Nevada between July 2016 and May 2017.
Between July 2017 and May 2018 — the first 11 months of legal recreational marijuana — 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.)
One of the concerns of recreational marijuana opponents was that traffic fatalities and DUI arrests would increase if pot 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.
