It’s also important to note that the amount of nicotine in a product can be different from how much a person absorbs from normal use. A person will typically absorb 1-2 milligrams from smoking a cigarette, while nicotine replacement products (gum, patches, nasal sprays, etc.) are usually designed to deliver 1-4 mg per hour.
