[27] [28] An average cigarette yields about 2 mg of absorbed nicotine. [29] The estimated lower dose limit for fatal outcomes is 500–1,000 mg of ingested nicotine for an adult (6.5–13 mg/kg). [27] [29] Nicotine addiction involves drug-reinforced behavior, compulsive use, and relapse following abstinence. [30]
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 ...
Between 1933 and the late 1940s, the yields from an average cigarette varied from 33 to 49 mg "tar" and from less than 1 to 3 mg nicotine. In the 1960s and 1970s, the average yield from cigarettes in Western Europe and the USA was around 16 mg tar and 1.5 mg nicotine per cigarette. Current average levels are lower. [4]

The numbers can vary, but Christensen often tells patients to think of one cigarette as having 5 to 10 milligrams of nicotine each, with the actual amount inhaled probably less than that.
Nicotine gum is commonly available in two strengths: 2 mg and 4 mg. Dosing is based on cigarette usage. [6] Individuals who smoke their first cigarette within 30 minutes of waking up or smoke more than 25 cigarettes daily are recommended to use the 4 mg gum.
A cigarette delivers an average of 1 mg to 3 mg of the nicotine contained in it. NRT products typically aim to parallel this, but the amount of nicotine absorbed by the user is less than the original dose. Nicotine nasal sprays are formulated in doses of lowest strength, available in 0.5 mg and 1 mg strengths.
