and most products used were prepackaged, prefilled cartridges, according to new data released by the Centers for Disease Control and Prevention.
The majority of these products (66%) were THC-containing cartridges marketed under the brand name Dank. Dank cartridges are available at legal dispensaries and online in areas where they are legal. The Dank company posted a statement on its website warning buyers about fake cartridges and showing images of genuine cartridges. However, 89% of the cartridges were obtained on the street, from dealers, online, or from friends or social contacts, Jennifer Layden, MD, of the Illinois Department of Public Health said during a CDC telebriefing.
The illness was first recognized in Wisconsin and Illinois. Marijuana is illegal in Wisconsin; Illinois licensed recreational marijuana in 2009.
Other commonalties among cases have also emerged, Anne Schuchat, MD, deputy director of CDC, said during the call. More than two-thirds of the 805 confirmed or probable cases were male, and the median age was 23 years. The illness crosses age barriers, she said. About 62% were 18-24 years of age, and 54% under age 25. However, among the 12 deaths so far reported, the median age was 50 years. The age range was wide, from 27 to 71 years. Dr. Schuchat said data about medical comorbidities potentially linking the deaths is not yet available, although it is part of the ongoing investigation.
Other clinical commonalities included intensive use of THC-containing products and, in a small number of cases, concomitant use of benzodiazepenes, opioids, and narcotics.
Cases have now emerged in 46 states and in the U.S. Virgin Islands, although the number reported each week is dropping. However, this decrease may not represent a drop in newly occurring cases, but instead reflect delays in clinical recognition or reporting to local health departments, Dr. Schuchat said.
Regardless of the recent decline in reported cases, she said, the epidemic is serious, far reaching, and ongoing.
“I want to stress that this is a serious, life-threatening disease occurring mostly in otherwise healthy young people. These illnesses and deaths are occurring in the context of a dynamic marketplace with mix of products with mixes of ingredients, including potentially illicit substances. Users don’t know what’s in them and cannot tell from the ingredients listed on the packaging.”
Dr. Schuchat drew her data from two reports issued in the Morbidity and Mortality Weekly Report: a national case update by Peter A. Briss, MD, chair of CDC’s Lung Injury Response Epidemiology/Surveillance Group, and colleagues, and a regional report coauthored by Dr. Layden of cases in Illinois and Wisconsin.
In the national report, 514 patients self-reported their history of e-cigarette and vaping use. Among those, 395 (76.9%) reported using THC-containing products, and 292 (56.8%) reported using nicotine-containing products in the 30 days preceding symptom onset. Almost half (210; 40.9%) reported using both THC- and nicotine-containing products.
But there appeared to be no clear pattern of use, said Dr. Briss, who also participated in the briefing. More than a third (185; 36.0%) reported exclusive use of THC-containing products, and 82 (16.0%) reported exclusive use of nicotine-containing products.
The regional report added additional details.
Among the 86 patients who self-reported details, there were 234 unique cases of e-cigarette or THC vaping in 87 brands.
“Patients reported using numerous products and brands,” Dr. Layden noted. “Those who reported using THC products used an average of 2.1 different products and those who reported using nicotine products used about 1.3 different ones. Some patients reported using up to seven different brands, and these were used at least daily and sometimes numerous times in the day.”
According to the MMWR regional report, among the urinary THC screens obtained for 32 patients, “29 (91%) were positive for THC. One of these patients reported smoking combustible marijuana. Urinary THC levels for four patients who reported using THC-containing products exceeded 400 ng/ml, indicating intensive use of THC or THC-containing products.”
About 40% of THC users and 65% of nicotine-product users reported using the product at least five times a day; 52% said they used combustible marijuana in addition to the vapes, and 24% reported also smoking combustible tobacco.
There was a very low level of concomitant drug use. Two patients reported using LSD; one reported misusing dextroamphetamine-amphetamine (Adderall), and one reported misusing oxycodone. Two tested positive for benzodiazepines and opioids, and one each for only benzodiazepines, only opioids, only amphetamines. One patient screened positive for unidentified narcotics.
