According to a study published in the July issue of the Archives of Pediatrics and Adolescent Medicine, 10% of 217 studied children who inhaled cigarettes "lost autonomy over their tobacco" use within two days of their first cigarette. Another quarter became addicted within thirty days, and a full half were addicted after smoking only seven cigarettes per month.
The conclusions contradict "conventional wisdom" which believed that it took multiple cigarettes (at least five to six) per day to become addicted to nicotine.
It isn’t long term use that causes addiction, a study author noted, but it is the addiction that causes the heavy use.
