Detection and concentration estimation of tetrahydrocannabinol (THC), the active ingredient in cannabis, is an
urgent technical challenge because of road safety issues and health/legal concerns. It is particularly important to differentiate this substance from other volatile organic compounds (VOCs) in air and breath. Here, we report using a virtual sensor array made by a thermal shock-induced tin oxide gas sensor for the detection, recognition, and concentration estimation of THC in air. The presented sensory system is capable of distinguishing THC from VOCs such as ethanol, propanol, acetone, and toluene, and can be trained to perform analyses on binary alcohol-THC gas mixtures.
