So far, almost 1,300 cases of vaping-related lung illnesses have been reported in 49 states.
"Given that the exclusive use of nicotine-containing products has been reported by a small percentage of persons with EVALI, and that many persons with EVALI report combined use of THC- and nicotine-containing products, the possibility that nicotine-containing products play a role in this outbreak can not be excluded", the CDC said Friday.
According to the U.S. Centers for Disease Control and Prevention (CDC), there had been 1,299 suspected cases and 26 deaths related to lung diseases associated with the use of liquid e-cigarettes, as of last Tuesday.
In its Morbidity and Mortality Weekly Report issued on October 11, the CDC called the lung illnesses EVALI, which stands for "e-cigarette or vaping product use associated lung injury". Seventy-three Minnesotans, who have experienced severe lung injury in this outbreak associated with vaping illegal THC over the past several months, is too many. Some used nicotine products as well as other types, such as those that contain THC.
They also advise that people "consider refraining" from using vaping products that contain nicotine.
In particular, THC vaping products obtained "off the street" or from family members or friends "play a major role in the outbreak", the CDC conclude.
Schuchat said the illness might have more than one cause, and the cause could vary throughout the United States.
"Should not use e-cigarette, or vaping, products that contain THC". "However, based on what we know about other patients, the seriousness of the injuries and the fact that we continue to see new cases, it is possible we will have more deaths". "We have not yet determined whether the lung disease is associated with vaping".
The CDC and FDA have not identified the cause or causes of the lung injuries in these cases, and the only commonality among all cases is that patients report the use of e-cigarette, or vaping, products.
DPHHS State Epidemiologist Laura Williamson thanks all those who are cooperating with the investigations that are occurring around the state.
