In this study the federal health investigators are focusing on illicit THC compounds as they search for the cause of a rash of vaping related respiratory illnesses that struck teens and young adults this summer. Health officials have interviewed eight of 15 patients in Minnesota who have been hospitalized for severe respiratory illnesses with confirmed links to vaping. All inhaled THC, the psychoactive compound in marijuana that creates a high sensation, said Richard Danila, epidemiology program manager for the Minnesota Department of Health.
Hospitalizations respiratory illnesses
“True for Minnesota: all of the ones we’ve interviewed, eight of eight, said they used an illegal THC product,” Danila said Tuesday. Another nine hospitalizations for respiratory illnesses have report to the state; but investigators haven’t confirm their links to vaping yet; either by interviewing the patients or reviewing their medical records.
Nationally, more than 200 similar cases have report this summer; though not all have confirm as vaping relate. In Minnesota, the hospitalized patients range in age from 16 to 23. At least seven suffer such severe injuries that they require intensive care; also four need to be intubate and placed on ventilators to breathe.
State health officials have warned teens in the past about vaping with legal nicotine products; because of the lack of regulation over their contents and because harmful metals and other substances have been found in some vaping liquids. However, those products do not appear to be the problem in this outbreak; though many of the injure teens vaped THC and nicotine before they were hospitalized.
Vaping illicit THC products
Not all patients nationally have admitted to vaping illicit THC products; but Danila said that could be because they didn’t know; or don’t want to admit it. He acknowledged it has taken time to build trust with the injure Minnesota teens; also assure them that information provide to the Health Department for this investigation; which can’t be turn over to law enforcement agencies. “You can think about how difficult this investigation is,” he said.
“You have a 17-year-old in the ICU. Are they going to tell you they used an illegal product? Are they going to tell you they use an illegal product when mom or dad are standing in the same room?” None of the injuries so far have involve people who exclusively vape legal THC products obtained from authorized medical marijuana distributors, Danila said. In many instances; the teens suffered anxiety or mental disorders; also vaped illicit substances as a form of self-medication, he noted.
As the probe continues, investigators hope to examine the product types the patients vape; also the delivery systems that they used to identify a common cause of the injuries and one death reported in Illinois. At least three hospitalized patients in Minnesota provided samples of their THC products for testing by federal authorities. Danila said the state health lab is preparing to conduct its own testing as well to hasten the search for the cause of the injuries.
