420 with CNW — Federally Funded Research Reports Breakthrough in Marijuana Breathalyzer Development
A newly published study points to a possible step forward in efforts to create a cannabis breathalyzer, offering early evidence that a compact and affordable device could detect recent cannabis use without requiring laboratory testing. The research, led by Virginia Commonwealth University’s Emanuele Alves, focuses on addressing a long-standing gap in roadside testing.
