This study aims to investigate the occurrence of nicotine dependence following the achievement of previous smoking milestones (initiation, weekly, and daily smoking).
Analyses are based on data from The National Comorbidity Survey-Adolescent, a nationally representative face-to-face survey of 10,123 adolescents (age 13-17) conducted between 2001 and 2004.
Among adolescents who had ever smoked (36.0%), 40.7% reached weekly smoking levels and 32.8% had reached daily smoking. Approximately one in five adolescents who had ever smoked (19.6%) met criteria for nicotine dependence. An earlier age of smoking initiation, a shorter time since the onset of smoking and faster transitions among smoking milestones were independently associated with the onset of daily smoking and nicotine dependence.
These findings shed new light on the course of smoking and nicotine dependence during adolescence by demonstrating a rapid transition across smoking stages for those most at risk for the development of chronic and dependent use.
本研究旨在探讨在达到以前的吸烟里程碑（起始、每周和每日吸烟）后尼古丁依赖的发生情况。
分析基于 2001 年至 2004 年间进行的全国共病调查-青少年的全国代表性面对面调查的数据，该调查共涉及 10123 名青少年（年龄 13-17 岁）。
在曾经吸烟的青少年中（36.0%），40.7%达到了每周吸烟水平，32.8%达到了每日吸烟水平。大约五分之一曾经吸烟的青少年（19.6%）符合尼古丁依赖的标准。较早的吸烟起始年龄、较短的吸烟起始时间和更快的吸烟里程碑之间的过渡，与每日吸烟和尼古丁依赖的发生独立相关。
这些发现通过证明那些最容易出现慢性和依赖使用风险的人在吸烟阶段的快速过渡，为青少年时期的吸烟和尼古丁依赖的发展过程提供了新的认识。
