I don't see how you can OD on nicotine from smoking, before my father passed he was smoking a cigarette about every few minutes, he died from something that had nothing to do with cigarettes.
From wiki...
The LD50 of nicotine is 50 mg/kg for rats and 3 mg/kg for mice. 40–60 mg (0.5-1.0 mg/kg) can be a lethal dosage for adult humans.[33][34] Nicotine therefore has a high toxicity in comparison to many other alkaloids such as cocaine, which has an LD50 of 95.1 mg/kg when administered to mice. It is impossible however to overdose on nicotine through smoking alone (though a person can overdose on nicotine through a combination of nicotine patches, nicotine gum, and/or tobacco smoking at the same time.) [35][36] Spilling an extremely high concentration of nicotine onto the skin can result in intoxication or even death since nicotine readily passes into the bloodstream from dermal contact.[37]
