Question: 12 mg nicotine equals how many cigarettes?
Answer: The average cigarette contains about 10 to 12 mg of nicotine. You don't inhale every milligram of nicotine as it burns. You'll probably inhale about 1.1 to 1.8 mg of nicotine by the end of each cigarette. This means that for a pack of 20 cigarettes, you'll likely inhale between 22 to 36 mg of nicotine.
