AP PSYCHOLOGY

Detailed explanation-1: -Nicotine acts as both a stimulant and a depressant to the central nervous system. 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.

Detailed explanation-2: -Both nicotine and caffeine are psychomotor stimulants. Caffeine, through inhibition of adenosine, increases the activity of the dopaminergic system, and it shows the reinforcing and the psychomotor effect.

Detailed explanation-3: -Anxiety Relief from Nicotine Is Temporary Many people turn to cigarettes when they are anxious, and the physiological effects of nicotine can create a calming sensation. But nicotine only produces temporary relief from anxiety while also compromising overall physical health.

Detailed explanation-4: -Nicotine is a stimulant drug that speeds up the messages travelling between the brain and body. It is the main psychoactive ingredient in tobacco products and so this Drug Facts page will focus on the effects of nicotine when consumed by using tobacco.
