Link between e-cigarette flavors and lung disease
Flavored e-cigarettes may seem like an alternative to smoking, but researchers warn that flavored e-cigarettes may not be worth the unknown long-term risks.
Researchers at the Harvard University T.H. Chan School of Public Health tested 51 types of flavored e-cigarettes and flavor canisters for diacetyl, acetoin, and 2,3-pentanedione; three chemicals known to cause respiratory problems in factory workers.
The study tested popular e-cigarette flavors like bubble gum, cotton candy and tutti frutti, and found, at least one of the three chemicals were present in 47 of the 51 products they tested.
Diacetyl has been directly linked to “bronchiolitis obliterans,” which in serious cases can require lung transplants, according to Robert Kotloff, chair of pulmonary medicine at Cleveland Clinic.
