Brain is the organ that nicotine targets that results in changes to mood and anxiety.
Nicotine is the habit-inducing drug in tobacco, and it is a stimulant that disrupts mood.
Nicotine binds to nicotinic receptors in the nervous system, where a structural change occurs in the subunits that make it up and the channel opens, allowing ion flow and the release of neurotransmitters.
In this way, nicotine increases the release of some neurotransmitters at the brain level such as dopamine and norepinephrine that generate feelings of pleasure and alertness, which enhances the reinforcing properties.
Together with these primary reinforcing properties, the action of nicotine exerts a greater effect in stressful situations, which would explain its greater addictive potential in people who are subjected to high levels of stress, or who feel anxious and / or depressed.
Therefore, we can conclude that brain is the organ that nicotine targets that results in changes to mood and anxiety favoring the release of some neurotransmitters such as dopamine that regulates desires, motivations and behaviors that provide us with pleasant sensations.
