What’s that on your breath? In episode 79 of Parsing Science we talk with Neil Garg from UCLA about his research into the fundamental chemistry necessary for the creation of a small, electronic test of marijuana that works by way of a simple electrochemical oxidation process similar to that used in an alcohol breath test. His open access article “Electrochemical Oxidation of Δ9 [delta 9] ‐Tetrahydrocannabinol: A Simple Strategy for Marijuana Detection,” which he published with Evan Darzi on April 24, 2020 in the American Chemical Society journal Open Letters.
