In this and prior studies we used a dabbing platform to heat and aerosolize cannabinoids. Dabbing is a type of cannabis vaping that entails flash vaporizing manufactured cannabis products (e.g, high THC-or CBD-potency extracts) on a hot surface (colloquially referred to as a nail), with users often inhaling close to an entire lung volume in one puff. A national web survey of cannabis consumers found that 60% of respondents dabbed at least once, and that 38% endorsed its regular use. Apart from embodying a popular means of cannabis vaping, using a dab platform has experimental advantages compared to vape pens. For example, the aerosols produced are not as prone to the influences of solvent, viscosity, or wicking that can significantly impact vaping chemistry and aerosolization efficiency. The specific aerosolization and collection method used herein has been described by us previously, with minor changes (see Supporting Information). Briefly, the cannabinoid sample (~100 mg) is flash vaporized on a quartz dab platform surface and the generated aerosol pulled via a smoking machine into an in-line impinger. The impinger contains NMR solvent (CDCl 3 ) and the trapping agent (benzylamine) at room temperature. Aliquots of the impinger solution containing the dissolved aerosol contents generated by a single puff are directly analyzed by NMR and GC-MS. The yield of ketene (as N-benzylamide equivalents) formed from 40 mg CBN-OAc under these conditions is 0.078 ± 0.016 mg (n=4) at 378 °C. 7
