How do you absorb nicotine?

There are three main ways that nicotine can be absorbed into the body:

1. Inhalation: When you smoke a cigarette, cigar, or pipe, you inhale nicotine directly into your lungs. The nicotine is then absorbed through the thin lining of the lungs and into the bloodstream.

2. Skin contact: Nicotine can also be absorbed through the skin. This can happen if you touch tobacco products or if you come into contact with secondhand smoke.

3. Ingestion: Nicotine can also be ingested if you swallow tobacco products or if you eat food that has been contaminated with nicotine.

Once nicotine is absorbed into the body, it travels to the brain where it binds to nicotine receptors in the brain. This binding causes the release of dopamine, a neurotransmitter that is involved in feelings of pleasure and reward. This is why smoking and other forms of nicotine use can be so addictive.

Nicotine is a poisonous substance and can cause a number of health problems, including cancer, heart disease, and stroke. It is also addictive and can be difficult to quit using.
