Yet, Narby explains that the view of nicotine as an addictive and destructive compound isn’t the whole story. Nicotine has a similar structure to the neurotransmitter
acetylcholine, meaning it can bind to receptors in our bodies, potentially influencing processes like learning and memory to muscle control. Inside the body, nicotine can trigger the release of acetylcholine along with a cascade of dopamine, glutamate, adrenaline, and endorphins. The ensuing interactions trigger pleasure, euphoria, and wakefulness, which might come with
cognitive effects like improved attention and memory—along with potential for dependence.
