A major federal science agency is pushing back its much-anticipated workshop on cannabis breathalyzer technology to this summer. Originally set for April 16–17 in Boulder, Colorado, the event—hosted by the National Institute of Standards and Technology (NIST)—aims to spark open, honest discussion about how to develop and implement tools to detect marijuana impairment through breath testing. While the exact new date hasn’t been announced, NIST says it’s still moving forward with the event, promising an important step in shaping the future of cannabis safety and regulation.
