What is a key symptom of tobacco withdrawal?

A key symptom of tobacco withdrawal is depressed mood. This symptom can manifest due to the sudden lack of nicotine, which the brain has become accustomed to receiving. Nicotine stimulates the release of dopamine, a neurotransmitter associated with pleasure and reward. When someone stops using tobacco, the absence of nicotine can lead to feelings of sadness, irritability, and sometimes anxiety, as the brain is adjusting to the absence of the substance it has relied on for mood regulation.

The symptoms of tobacco withdrawal can vary but often include depressive symptoms, increased cravings for nicotine, difficulty concentrating, and changes in appetite. Understanding these withdrawal symptoms is essential for effective smoking cessation strategies and support.
