Nicotine dependence is a condition where a person becomes reliant on nicotine, a chemical found in tobacco products. This dependence often develops after repeated use, leading to cravings and withdrawal symptoms when not using tobacco. It can affect anyone who smokes or uses nicotine in other forms, such as vaping. The body adapts to the presence of nicotine, making it difficult to quit. People with nicotine dependence may find themselves smoking more frequently or in larger amounts to achieve the same effects. Treatment options include counseling, medications, and support groups to help individuals overcome their dependence.
