An "e-cig," or electronic cigarette, is an alternative to smoking traditional cigarettes. Its appearance is a small elongated tube, most usually in the same general shape of a real cigarette, that delivers a dose of nicotine when inhaled. When exhaled, "smoke" is visible, though the smoke is actually just water vapor. For this reason, the use of e-cigs is allowed nearly everywhere, which is one of the many reasons it's greatly preferable to traditional or "analog" cigarettes. As water vapor is exhaled, and not actual smoke, there's no smell left over to stink up your clothes, house or car. No more smoker's breath, no more social stigma, and no ash. Best of all, no matter what brand of e-cig you end up using, it costs waaaay less than traditional cigarettes.
