A Cannabinoid Fuel Cell Capable of Producing Current by Oxidizing Δ 9-Tetrahydrocannabinol

We report the development of a current-producing H-Cell that relies on the oxidation of Δ⁹-tetrahydrocannabinol (THC), which is the primary psychoactive ingredient in marijuana. We found through systematic investigation of several variables that power densities could be improved 5-fold. Moreover, a real-time signal in a rudimentary THC sensor was observed at varying concentrations of THC. Given the growing societal interest in the detection of THC, our studies lay the foundation for the development of a marijuana breathalyzer.
