Similar to breathalyzer tests for alcohol, marijuana breathalyzer tests have hit the market, but there is one challenge that separates the two: THC doesn’t last very long on the breath. This type of test cannot pick up on impairment, either, so it is often pitched as a “recent use test,” which does not always mean the individual is impaired. Top breathalyzer companies include Cannabix, Hound Labs, and ElectraTect, but one – Gaize – uses impairment detection technology to measure the body’s response to the drug, rather than looking simply for its traces in the system.
