Immediately after exposure to nicotine, there is a “kick” caused in part by the drug’s stimulation of the adrenal glands and resulting discharge of epinephrine (adrenaline). The rush of adrenaline stimulates the body and causes an increase in blood pressure, respiration, and heart rate.
How does nicotine affect adrenaline in the body?
The ‘nicotine effect’ Nicotine is both a sedative and a stimulant. When a body is exposed to nicotine, the individual experiences a “kick.” This is partly caused by nicotine stimulating the adrenal glands, which results in the release of adrenaline. This surge of adrenaline stimulates the body.

Nicotine first causes a release of the hormone epinephrine, which further stimulates the nervous system and is responsible for part of the “kick” from nicotine-the drug-induced feelings of pleasure and, over time, addiction.
How does nicotine affect norepinephrine?
Through the intracardiac release of norepinephrine, nicotine induces a beta-adrenoceptor-mediated increase in heart rate and contractility, and an alpha-adrenoceptor-mediated increase in coronary vasomotor tone.
Does nicotine have any positive effects?
Some studies show nicotine, like caffeine, can even have positive effects. It’s a stimulant, which raises the heart rate and increases the speed of sensory information processing, easing tension and sharpening the mind.
