USA: The Innocent Electronic Cigarette As it was found, those who had a vapor problem had purchased refill liquids from the internet or the street and not from legally controlled stores. Following the deaths from the vaporization of certain products, US health authorities had banned all electronic cigarette products until tests were confirmed and the origin of the risk to consumers was confirmed.
Research has shown that nearly 3,000 cases of pulmonary artery disease are responsible for the black market products of THC (H-trans-Δ-tetrahydrocannabinol or, alternatively, Δ-THC is the substance found in dried marshmallows, of the hemp plant). It was also found that those who had a vapor problem had purchased refill liquids from the internet or the street rather than from legally controlled stores.
Research by the Center for Disease Control and Prevention (CDC), published in the New England Journal of Medicine, confirmed that 82% of cases of lung disease occurred in patients using THC products. Only 14% said they only used nicotine replacement fluids. And that percentage is attributed either to refusing to accept marijuana oil or because they ignored the ingredients as they were supplied by the street or friends. Now, the CDC separates the hitherto often linked interconnected epidemics of youth vomiting and lung disease called EVALI.
Although new cases are still being reported, the CDC says the increase is slowing and health workers are no longer recommending current and former smokers to avoid electronic cigarettes, though they continue to stress that vaping is not safe for teens and children. Competent authorities continue to urge consumers to avoid any illicit foul products or products from "unofficial sources" such as street vendors, friends and family who claim that no trace of Vitamin E acetate has been added to the e-cigarette packaging.
