In Colorado, nearly 70% of marijuana users admit driving stoned – many of them, daily. That’s a lot of high drivers on the road next to you. It’s no surprise the number of traffic deaths involving drivers with THC in their system in Colorado doubled after voters legalized recreational marijuana.

It’s not just a problem in Colorado, Washington state daytime drivers with THC in their system almost tripled after passing recreational marijuana. Other “legal” states saw similar results.

The increased danger on the roads is one of the most significant drawbacks of Prop 207, because the initiative does nothing to stop it. In fact, it actually eliminates current law prohibiting driving with THC in one’s system. The language in the initiative is, “driving impaired remains illegal.” But it offers no standard for determining that impairment. With the only law establishing impairment – the presence of THC – off the books, Prop 207 leaves the issue in the hands of police officers and courts. It will be litigated for years to come because the initiative makes using marijuana a statutory right.

In addition, Prop 207 makes it more difficult for police officers to immediately remove stoned drivers from the roadway, because there is no reliable roadside testing to measure impairment like there is for alcohol.

For these reasons and others, the Arizona Troopers Association opposes Prop 207. As does

the Arizona Sheriff’s Association, health care industry leaders, and more. See the full list here.

Two additional points to remember:

  • Those who need marijuana for medical reasons can already access it. Rejecting Prop 207 would do nothing to change Arizona’s current medical marijuana law.
  • Arizona laws passed by ballot initiatives are nearly impossible to fix or change. The state legislature cannot fix problems that arise. If Arizonans pass Prop 207, we are stuck with it – as is.
