Nicotine addiction is a chronic condition characterized by the compulsive use of nicotine, primarily found in tobacco products. It leads to physical and psychological dependence, making it difficult for individuals to quit despite the known health risks associated with smoking and other forms of tobacco use. The addiction is often fueled by the immediate effects of nicotine, such as increased alertness and mood enhancement. Over time, the body becomes accustomed to nicotine, resulting in withdrawal symptoms when not consumed. These symptoms can include irritability, anxiety, and cravings, which can make quitting a challenging process. Support and treatment options, such as counseling and medications, can help individuals overcome nicotine addiction and improve their overall health.
