"According to preliminary statistics, roughly 27 percent of the blood tests for suspected impaired driving showed detectable THC. Before this year, that number was around 20 percent. That's a 7-point jump in the months since legalization."
What the story did not include was information about how many of those marijuana DUIs were among minors. According to the state toxicologist:
- Typically, one quarter of those cases confirming positive for THC are aged under 21 years.
- Marijuana is the most frequently detected drug in those aged under 21 years (including alcohol).
