Most smokers are dependent on nicotine. Smokeless tobacco use can also lead to nicotine dependence.
Nicotine dependence is the most common form of chemical dependence in the United States.
Research suggests that nicotine is as addictive as heroin, cocaine, or alcohol.
Examples of nicotine withdrawal symptoms include irritability, anxiety, difficulty concentrating, insomnia, restlessness, and increased appetite.
Quitting tobacco use is difficult and may require multiple attempts.
FDA-approved medications that can reduce the withdrawal symptoms that may occur with a quit attempt are available.
For more information regarding FDA-approved medications, call 1-800-QUIT-NOW or speak with your health care provider.
