戒烟的影响，如尼古丁戒断和情绪变化有助于维持吸烟的成年吸烟者，和青少年吸烟者的新报告表明，他们可能会遇到类似的主观影响时，剥夺。本研究的目的是前瞻性地记录戒烟引起的变化，在第一个48小时的禁欲青少年吸烟者与非吸烟者相比，区分效果不同的典型的青少年lability.METHODS五十七青少年吸烟者和44青少年非吸烟者进行了评估，在48小时的住院会议。特征尼古丁戒断症状，对香烟的渴望，和情绪症状进行了测量，在13个时间点后开始abstinence.STSTSThe唯一的禁欲相关的影响观察到的变化，对烟草的渴望和愤怒的感觉。戒烟开始后，烟草渴望迅速增加并达到峰值，并在48小时戒烟期结束时略有下降，而愤怒症状在更长时间的戒烟后达到峰值。总体而言，吸烟者的症状和渴望与每日吸烟量呈正相关，但不与报告的依赖性或生物措施的程度use.CONCLUSIONSWe观察到，在青少年吸烟者中，与戒烟相关的主要影响是相对最小的，并包括一个高度和持久的渴望吸烟和愤怒的增加。虽然吸烟者与非吸烟者相比有更大的负面情绪症状，但大多数这些症状的存在和严重程度似乎都不会因戒烟而发生变化，并且与烟草使用量的依赖性或生物指标无关。
PURPOSEAbstinence effects such as nicotine withdrawal and mood changes contribute to the maintenance of cigarette smoking in adult smokers, and emerging reports on adolescent smokers suggest they may experience similar subjective effects when deprived. This study aimed to prospectively document tobacco abstinence-induced changes during the first 48 hours of abstinence in adolescent smokers compared with nonsmokers, to distinguish effects distinct from typical adolescent lability.METHODSFifty-seven adolescent smokers and 44 adolescent nonsmokers were assessed during a 48-hour inpatient session. Characteristic nicotine withdrawal symptoms, cravings for cigarettes, and mood symptoms were measured at 13 time points following initiation of abstinence.RESULTSThe only abstinence-related effects observed were changes in craving for tobacco and feelings of anger. Tobacco craving increased and peaked quickly following initiation of abstinence and displayed a slight decrease toward the end of the 48-hour abstinence period, while anger symptoms peaked after a more prolonged abstinence. Overall, smokers' symptoms and cravings were positively associated with amount of daily smoking but not with reports of dependence or biological measures of extent of use.CONCLUSIONSWe observed that among adolescent smokers, the primary effects associated with abstinence from cigarettes are relatively minimal, and include a heightened and persistent craving to smoke and increases in anger. Although smokers had greater negative mood symptoms compared with nonsmokers, the presence and severity of most of these symptoms appear to be minimally altered by abstinence and not associated with dependency or biological indicators of amount of tobacco use.
