Which effect does nicotine have on anxiety?

Nicotine has been observed to reduce anxiety in some individuals. This effect is likely due to its action on nicotinic acetylcholine receptors in the brain, which can lead to the release of neurotransmitters such as dopamine and serotonin, both of which are implicated in mood regulation and anxiety control. The initial stimulation of the central nervous system by nicotine can produce feelings of pleasure and relief from anxiety, thereby providing a temporary reduction in anxious feelings.

However, it's important to note that while some users may experience an acute reduction in anxiety, chronic use of nicotine can have complex effects, and dependence on nicotine might ultimately lead to increased anxiety when the substance is not available. This underscores the dual nature of nicotine's impact on mental health, where its short-term effects may not reflect long-term outcomes.
