Nicotine is a highly addictive drug. Smoking is not only a physical addiction, but also becomes linked with many social activities and coping needs, making it a difficult habit to break. When someone addicted to nicotine stops smoking they may experience withdrawal symptoms such as increased anger, hostility, and anxiety. Nicotine replacement therapies combined with behavior change programs providing psychological support and skills training result in the highest long-term abstinence rates. Generally, rates of relapse for smoking cessation are highest in the first few weeks and months and lessen considerably after about three months.
