[51] It acts on the nicotinic acetylcholine receptor, and gave the receptor its name. Nicotine is in IRAC group 4B.
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 ...

In the 1970s, Brown & Williamson cross-bred a strain of tobacco to produce Y1, a strain containing an unusually high nicotine content, nearly doubling from 3.2 to 3.5%, to 6.5%. In the 1990s, this prompted the Food and Drug Administration to allege that tobacco companies were intentionally manipulating the nicotine content of cigarettes. [24]
