What is nicotine and how does it affect the body?

Nicotine is an alkaloid found in certain plants, predominantly tobacco, and in lower quantities tomato, potato, eggplant and green pepper. When absorbed in small amounts, whether from cigarettes or e-cigarette, nicotine can cause stimulation, a feeling of relaxation, calmness, and alertness. The effects of nicotine can last from minutes to hours. The carcinogenic properties of nicotine in a standalone form (i.e., separated from smoking or chewing tobacco) have not been evaluated by the International Agency for Research on Cancer, however current available literature indicates that nicotine in standalone form does not promote the development of cancer in healthy tissue and has no mutagenic properties.
