[128] [75]: 12 A 2014 study reported that limited evidence suggests that e-cigarettes produce less short-term effects on lung function than traditional cigarettes. [129] As of 2015 many e-liquid ingredients had not been examined in the lung. [98]
A recent study found that smoking an e-cigarette decreased the amount of oxygen being taken in by the lungs, ... vaping, like smoking, has an immediate negative effect on the user’s blood flow ...

An 18-year-old's vaping-related illness left him with lungs that more closely resemble a 70-year-old's than those of a teenager, according to his doctors.
The CDC's findings were based on fluid samples from the lungs of 29 patients with vaping-associated pulmonary injury, which provided direct evidence of vitamin E acetate at the primary site of injury in all the 29 lung fluid samples tested. [35] Research suggests when vitamin E acetate is inhaled, it may interfere with normal lung functioning ...
The LD 50 of nicotine is 50 mg/kg for rats and 3 mg/kg for mice. 0.5–1.0 mg/kg can be a lethal dosage for adult humans, and 0.1 mg/kg for children. [19] [20] However the widely used human LD 50 estimate of 0.5–1.0 mg/kg was questioned in a 2013 review, in light of several documented cases of humans surviving much higher doses; the 2013 review suggests that the lower limit causing fatal ...
