To evaluate the effect of two inhaled essential oils (black pepper or angelica) on the nicotine habits of students, staff, and faculty on a U.S. college campus.
Comparative study with pre-/post-test measures.
Community college in rural East Texas.
Convenience sample of 20 volunteers from the college community (students, faculty, and staff) who were regular (daily) users of nicotine (cigarettes, snuff, or chewing tobacco).
Inhalation of one drop of essential oil on a tissue for 2 minutes when participant was craving nicotine.
(1) Pre-inhalation journal recording of self-assessed level of craving for nicotine on a 0-10 scale, (2) post-inhalation journal recording of self-assessed level of craving for nicotine on a 0-10 scale, and (3) minutes that participant waited from start of inhalation until next use of tobacco.
Both black pepper and angelica reduced the level of nicotine craving and allowed a longer delay before next use of tobacco. However, black pepper reduced the level of craving more than did angelica, and angelica allowed for a longer delay than did black pepper.
Aromatherapy may be useful in nicotine withdrawal. Further studies are warranted.
评估两种吸入用精油（黑胡椒或当归）对美国大学校园学生、教职工尼古丁习惯的影响。
有前后测的对比研究。
德克萨斯州东部农村的一所社区学院。
从学院社区（学生、教职员工）中抽取 20 名作为常规（每日）尼古丁使用者（香烟、鼻烟或咀嚼烟草）的志愿者作为方便样本。
当参与者渴望尼古丁时，在纸巾上吸入一滴精油 2 分钟。
（1）在吸入前记录自我评估的尼古丁渴望程度（0-10 分制），（2）在吸入后记录自我评估的尼古丁渴望程度（0-10 分制），（3）参与者从开始吸入到下一次使用烟草之间的等待时间。
芳香疗法可能有助于戒烟。需要进一步的研究。
