Is nicotine dangerous?

By itself, not particularly, compared to smoking. Smokeless nicotine does not carry the same risks as smoking does, but obviously most nicotine users are smokers and of course, smoking has serious health risks. It does increase blood pressure and heart rate in the short term, during use, much like caffeine does. In that respect, it’s likely at least as dangerous as drinking too much coffee! The strongest guidance against nicotine is to definitely avoid it during pregnancy.
