Due to its association with tobacco cigarettes however nicotine is in fact NOT one of the many harmful or potentially harmful constituents of cigarette smoke. Nicotine is a stimulant so therefore will have some effect on the body, in a similar way that other stimulants such as caffeine would have. While studies are cited that supposedly show the negative effects that nicotine has on the body, that it can increase the risk of heart attacks with chronic exposure.[6] These studies are exposing cells from the human body to such astronomical quantities of nicotine, that no human would ever be exposed to that level in everyday circumstances. The research so far seems to point to nicotine and vaping being as dangerous as drinking cups of coffee.
