When the leaves of Tobacco plants are smoked, the active chemical nicotine is absorbed by the body through the lungs and enters the bloodstream. When the Tobacco herb is chewed or sniffed, the nicotine contained within is absorbed through the mucous membranes in the mouth and nose, before it then travels to the brain.

​

Nicotine triggers the release of dopamine in the brain. This chemical dopamine plays a role in helping to regulate movement, learning, attention, and emotional responses. However, this chemical is most notably known for its association with pleasure in the brain. The underlying effects on the human body varies, and can result in either a stimulating, or relaxing sensation.
