Sometimes when you’re getting behind the wheel you know you’re dabbed the fuck out and it’s time to get out and chopper evac out of there. But other times your inebriation level is a little more nuanced. And that’s when maybe a new app developed by Arizona State University could be of some help.
The app uses the camera on a smartphone or tablet to monitor involuntary eye movements that happen when a little too much THC has entered the body. If an impairment is revealed, the app notifies the user so instead of getting behind the wheel, they can call a cab.
Determining if a driver is impaired by marijuana is still a gray area in the law. It’s illegal in all 50 states, but hard to enforce and test for. The best way to test for THC content in a driver is a blood-test, but those can’t be administered casually like a breathalyzer. And since THC can stay in the system days or weeks after being under the influence, results of tests can be inconclusive.
In Washington and Colorado, the limit for drivers is per se 5 nanograms per of active THC per milliliter of blood. For a full-time smoker, you could be perfectly sober at that level. In some states, like Wisconsin and Iowa, that per se limit is zero nanograms. Haziness over the law has resulted in some sober DUI’s and a good bit of head-scratching by law enforcement and cannabis enthusiasts alike.
Since the ASU app does not use the same criteria as law enforcement to determine inebriated driving, it can’t actually be used to tell if you’re susceptible to a DUI or not. But at the very least it’ll be fun to pass around and see who among your friends a robot says is the most dabbed out.
