Personal battery-powered vaporizers or electronic cigarettes were developed to deliver a nicotine vapor such that smokers could simulate smoking tobacco without the inherent pathology of inhaled tobacco smoke. With four states within the United States having legalized the cultivation, distribution, and recreational use of marijuana and an additional 23 states plus the District of Columbia with laws that legalize marijuana in some form, it was inevitable that suppliers of legal marijuana would develop marijuana products for use in these electronic cigarettes. The current study found that the cannabinoid concentrations in Liberty Reach, as determined by high-performance liquid chromatography-triple quadrapole mass spectrometry (HPLC-MS-MS), were significantly lower than the labeled concentrations. In addition, 4 cannabinoids, 13 marijuana terpenes, and propylene glycol were identified by a combination of Direct Analysis in Real Time-AccuTOF mass spectrometry (DART-MS), HPLC-MS-MS, and gas chromatography-MS.
