When a person quits "cold turkey", they don't use quit aids containing nicotine to help ease physical withdrawal. The biggest advantage of quitting cold turkey is that most of the nicotine from tobacco is out of the bloodstream within 3 days. Nicotine withdrawal symptoms tend to be more intense than if a nicotine replacement therapy (NRT) was used, but they are shorter-lived. This quit smoking method has a high rate of success when combined with a cessation program involving education, support, and determination.
