PSYCHOLOGY OF EMOTIONS

Detailed explanation-1: -Stimulants include caffeine, nicotine, amphetamines and cocaine.

Detailed explanation-2: -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-3: -Nicotine is a stimulant drug that speeds up the messages travelling between the brain and body.

Detailed explanation-4: -Tobacco is a plant (Nicotiana tabacum and Nicotiana rustica) that contains nicotine, an addictive drug with both stimulant and depressant effects.

Detailed explanation-5: -Current FDA-approved NRT products include chewing gum, transdermal patch, nasal sprays, inhalers, and lozenges. NRTs deliver a controlled dose of nicotine to relieve withdrawal symptoms while the person tries to quit.
