However, it has been found that the nicotine yield of individual products has only a small effect (4.4%) on the blood concentration of nicotine, [152] suggesting "the assumed health advantage of switching to lower-tar and lower-nicotine cigarettes may be largely offset by the tendency of smokers to compensate by increasing inhalation".

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 ...
A 2016 review found "The nicotine contained in the aerosol from 13 puffs of an e-cigarette in which the nicotine concentration of the liquid is 18 mg per milliliter has been estimated to be similar to the amount in the smoke of a typical tobacco cigarette, which contains approximately 0.5 mg of nicotine."
