Primary efect is to stimulate CNS receptors that are sensitive to acetylcholine, known as nicotine receptors. Activation of these receptors releases adrenaline and inhibits activity in the gastrointestinal system.

Nicotine









Nicotine acts as both a stimulant and sedative.
Immediately after nicotine exposure the user experiences a “kick” caused by the stimulation of the adrenal glands, which release epinephrine.
The rush of adrenaline causes a sudden release of glucose.
Nicotine suppresses insulin output, which makes the user slightly hyperglycemic.
Nicotine reaches the brain within ten seconds of entering the body.

Nicotine Addiction










Nicotine reaches the brain within ten seconds of entering the body.
Chew contains more nicotine than cigarettes. Increases the levels of dopamine by activating the circuitry.
An ingredient in tobacco causes a decrease in monoamineoxidase, which is responsible for breaking down dopamine.
This results in higher dopamine levels.

Reward Pathway








Upon entering the bloodstream nicotine immediately stimulates the adrenal glands to release epinephrine
(adrenaline).
Epinephrine stimulates the Central
Nervous System, which increases blood pressure, respiration, and heart rate.
Nicotine increases the levels of dopamine in the brain.
Acetaldehyde helps to enhance nicotine’s efects on the brain.
