Weed Breathalyzers in the Works

A company called Cannabix Technologies is developing a weed breathalyzer to keep up with the increased legalization of marijuana—and drivers that may be too stoned to drive. Current prototypes can detect Tetrahydrocannabinol (THC)—the cannabinoid that provides a high—up to two hours after consumption. Right now, the device is only set to report a “Yes” or “No” to the presence of the drug, but as states come closer to agreeing on the definition of “too high to drive,” later models may provide toxicity levels.
