Smoking and Addiction

In 1988, the U.S. Surgeon General identified nicotine as the addictive ingredient in tobacco, concluded that the addiction to nicotine is similar to the addiction to heroin or cocaine, and highlighted the critical role of addiction in the ongoing battle against tobacco use. A subsequent Surgeon General’s report stated that tobacco dependence is best viewed as a chronic disease with remission and relapse. The World Health Organization also recognizes tobacco use as an addiction stating that it is seen falsely as a personal choice and that most smokers want to quit but have difficulty because of the addiction.
