Nicotine in smoke has two forms; the electrically neutral form is more easily absorbed through the mucous membranes of the mouth, nose, and lungs.
<h3>Where is nicotine absorbed the most?</h3>
- Nicotine is absorbed through mouth mucous membranes and reaches peak blood and brain levels more slowly in people who do not inhale the smoke, such as cigar, pipe, and smokeless tobacco users.
- By "riding" in with the tar that is inhaled from a lit cigarette, nicotine enters the body. About 8 seconds after inhaling the smoke, the nicotine/tar mixture enters the lungs, where it is swiftly absorbed. It can move to the brain once it reaches the bloodstream.
