The influence of tobacco addiction on human brain activity

Apr 11, 2023

This paper discusses the effects of tobacco addiction on human brain activity and how this affects individuals’ ability to make decisions. Tobacco addiction has long been associated with various neurological diseases, including depression, anxiety, and cognitive impairment. Studies have shown that smoking cigarettes can alter brain activity in several ways. For example, smoking has been linked to changes in dopamine levels as well as increased glutamate release, both of which are associated with decreased cognitive flexibility and decision-making abilities. Additionally, studies have demonstrated that smokers tend to display lower activation in certain regions of the prefrontal cortex compared to non-smokers; these regions are involved in executive functioning such as working memory, decision-making, problem-solving, and inhibition control.


Furthermore, research suggests that nicotine dependence decreases one’s ability to effectively regulate emotions and behaviors, resulting in increased levels of impulsivity. This can further lead to disinhibition, which is characterized by decreased attentional control and an inability to resist temptations or make rational decisions. These findings suggest that nicotine dependence has a profound effect on individuals’ decision-making abilities, making it difficult for them to resist the urge to smoke cigarettes despite knowing the negative consequences associated with tobacco use.

In conclusion, this paper provides evidence of the detrimental effects of tobacco addiction on human brain activity and how this affects our ability to make decisions. We have seen that smoking cigarettes alters neurotransmitter activity in ways that can impair one’s executive functioning and inhibitory control; this leads to poor decision-making, impulsivity, and disinhibition. Thus, it is clear that tobacco addiction can have a significant impact on our ability to make informed decisions. As such, individuals with nicotine dependence should be aware of the risks associated with smoking and strive to quit in order to protect their cognitive health.
