New Mayo Clinic Study Further Implicates Contaminated THC Oils in Respiratory Disease Outbreaks and Refutes Claim that Store-Bought Nicotine E-Liquids are Involved

Astudy published yesterday in theNew England Journal of Medicine by a team of researchers at the Mayo Clinic provides further evidence that contaminated THC oils are likely playing a major role in the vaping-associated respiratory disease outbreak and makes it even less likely that store-bought nicotine e-liquids are playing any role at all. Here is the key evidence provided by the paper:1.The overwhelming majority of patients admitted to vaping THC oils.Approximately 76% of the patients studied who reported on product use admitted to vaping marijuana (13 out of 17 patients). Because urine THC testing was either not conducted or not reported, it is not possible to state that any of these cases occurred in a patient who had not vaped a marijuana-based product. In one case, a patient had been vaping nicotine e-liquids for five years, but then tried vaping marijuana and was in the hospital with respiratory distress within a few days. His vaping history was reported as: " vaping nicotine for 5 years; on weekend prior to presentation, started vaping nicotine with marijuana for the first time. "2.The study authors suspect a direct chemical injury to the lungs, suggesting that a new contaminant, not traditional nicotine e-liquids, is the most likely cause.After examining the lung biopsies, the authors concluded that the most likely explanation for these cases is " direct lung toxicity from an inhaled noxious agent or agents. " The ingredients of store-bought nicotine e-liquids is qu...
