Serotonin helps you maintain a feeling of general well-being and happiness.

Nicotine is the main psychoactive constituent found in tobacco that has been shown to be responsible for its behavioural and physiological effects, which can lead to addiction. Cigarette smoke contains several psychoactive chemicals; nicotine is the best studied among these and is widely accepted to be the addictive substance in tobacco. There it is absorbed into the pulmonary veins, which are blood vessels that collect oxygen from the lungs and displace the blood in the left atrium of the heart. A serotonin deficiency can lead to a variety of ailments such as insomnia, anxiety and depression. Potential explanatory models for this include the effects of smoking on neurotransmitters, neurobiology, respiratory health and autonomic control (Klein 1993; Niedermaier et al. There are three neurotransmitters: norepinephrine, dopamine and serotonin. • In Dance 1 neurotransmission is normal between all three cells, and includes four neurotransmitters …

Neurotransmitters are endogenous chemicals that enable neurotransmission.They are a type of chemical messenger which transmits signals across a chemical synapse from one neuron (nerve cell) to another 'target' neuron, muscle cell, or gland cell. Modulatory neurotransmitters: These neurotransmitters, often referred to as neuromodulators, are capable of affecting a larger number of neurons at the same time.

These neuromodulators also influence the effects of other chemical messengers. For example, your brain makes more endorphins in response to nicotine.

The most significant ingredient in tobacco smoke is nicotine, the component that causes addiction. Mechanism of Nicotine Action. Nicotine also increases the level of other neurotransmitters and chemicals that modulate how your brain works. As Neuroscience advances its knowledge of smoking’s impact on the central nervous system, it also finds the use of NRTs (nicotine replacement therapies) a viable option. Smoking, for instance, has been shown to interfere with dopamine production in a brain region called the basal ganglia, which is heavily involved in controlling the formation of habits. Tobacco smoke contains nicotine, which is addictive and can cause dependence. Nicotine exerts its effects in the brain by acting on a specific type of receptor for the neurotransmitter acetylcholine, known as the nicotinic receptor. Nicotine is the main psychoactive constituent found in tobacco that has been shown to be responsible for its behavioural and physiological effects, which can lead to addiction.
