Ive heard nicotine overdose is at 30-60mg. i also heard a cigarette has about 1 mg. 20 cigarettes is a pack, and ive heard a can of dip has as much nicotine as 3 packs. that means 60mg of nicotine in a can. but then i see people who do a full can or this one guy did 5 cans at ounce but how didnt they die?
