Mental and behavioural disorders due to use of tobacco

"Mental and behavioral disorders linked to tobacco use form a complex interplay between substance dependence and psychological health. This nexus reveals the intricate relationship between nicotine, brain function, and mental well-being. Tobacco consumption significantly impacts neurotransmitter regulation, altering the delicate balance of dopamine, serotonin, and norepinephrine, crucial chemicals influencing mood, cognition, and behavior.
This connection between tobacco and mental health manifests in various ways, exacerbating existing conditions such as anxiety, depression, and substance use disorders. The neurological impact of nicotine induces changes in brain structure, affecting neuronal plasticity and cognitive functions. Moreover, stress responses intertwine with tobacco use, creating a cyclical relationship where stress can trigger smoking, while smoking itself amplifies stress responses.
