Inhaling from just one cigarette can lead to nicotine addiction
This study from University of Massachusetts Medical School shows that 10 percent of youth who become hooked on cigarettes are addicted within two days of first inhaling from a cigarette, and 25 percent are addicted within a month. Recent research has revealed that the nicotine from one cigarette is enough to saturate the nicotine receptors in the human brain. “Laboratory experiments confirm that nicotine alters the structure and function of the brain within a day of the very first dose. In humans, nicotine-induced alterations in the brain can trigger addiction with the first cigarette,”
