Abstract
Chemical compositions and methods provide labeling, detection and measurement of target substances in exhaled human breath, and can be implemented in connection with a handheld device—much like a Breathalyzer portable breath testing unit for alcohol—to support rapid quantification of levels of cannabinoid compounds, such as tetrahydrocannabinol (THC), of suspected users at the roadside.
