Nicotine is definitely a pretty virulent poison. People seem to think it's no worse than caffeine but it's a far more potent alkaloid:

However for nicotine addicts the e-cigarette is certainly a better method of delivery than the cigarette, as you're not getting exposure to known carcinogens like benzo[a]pyrene etc.

> "Benzo[a]pyrene is a polycyclic aromatic hydrocarbon and the result of incomplete combustion of organic matter at temperatures between 300 °C (572 °F) and 600 °C (1,112 °F). The ubiquitous compound can be found in coal tar, tobacco smoke and many foods, especially grilled meats. The substance with the formula C20H12 is one of the benzopyrenes, formed by a benzene ring fused to pyrene. Its diol epoxide metabolites (more commonly known as BPDE) react with and bind to DNA, resulting in mutations and eventually cancer."
