The answer, it turns out, has to do with tobacco changing the way our brains work, making us want more of it, according to the U.S. Food and Drug Administration (opens in new tab) (FDA).

“Addiction is primarily defined as a loss of control on the use of a substance and continued use despite the consequences,” Bernard Le Foll, Chair of Addiction Psychiatry within the Department of Psychiatry at the University of Toronto, told Live Science in an email.
