Nicotine dependence commonly takes hold during adolescence because the brain’s reward systems are especially receptive to addictive substances during teen years, and many begin using regularly in that period. Because of this heightened vulnerability, a large majority of people who will develop tobacco use disorder do so by late adolescence or early adulthood. The threshold that best reflects when most regular users have already become dependent is around 21 years old, meaning by the time someone reaches 21, many have already developed tobacco use disorder. While some may become dependent earlier, at 18, or later at 25 or 30, these ages are less representative of the typical onset window.
