Nicotine, the addictive substance found in tobacco products, has been a subject of interest for researchers due to its potential impact on mood and mental well-being. Let's delve into the intricacies of this connection.

Nicotine is known to have a direct effect on the brain's neurotransmitters, particularly dopamine, which is associated with the brain's reward system.
