Don't know about cigars, but a cigarette has about 10 mg of nicotine in it. 90% of that is destroyed by burning and an even smaller amount actually enters the bloodstream (when smoked). Drinking it would be another matter.
Nicotine is water-soluble. If you soaked a cigarette in water, let's say that half (5mg) of the nicotine would leach into the water. This might be higher. If you drank it, you'd likely absorb let's say 75% of that. That's 3.75mg per cigarette.
Therefore if you dropped 15+ cigarettes into a glass of water, let it sit overnight, and chugged the water, you'd likely die or come very close to it. This is about the max. If given longer soak times and a smaller body which absorbs closer to 100% of the nicotine in the stomach, it could be as few as 5 cigarettes.
Not sure about cigars. Likely depends on the blend.
