Smokers, exsmokers and nonsmokers showed 50 to 150 minute cycles of consummatory behavior (eating and drinking) that appear to reflect a biological rhythm of oral drive. Smokers and exsmokers had significantly shorter cycles, i.e., more frequent consummatory peaks, than nonsmokers. If a greater frequency of consummatory peaks contributes to heightened oral drive in smokers, it may constitute a physiological factor underlying the initiation or maintenance of compulsive smoking and the degree of difficulty in quitting smoking and remaining abstinent.
吸烟者、曾经吸烟者和非吸烟者表现出50至150分钟的进食行为（饮食）周期，这似乎反映了口腔驱力的生物节律。吸烟者和曾经吸烟者的周期明显更短，即进食高峰更频繁，而非吸烟者则不然。如果进食高峰频率增加会导致吸烟者口腔驱力增强，那么这可能构成强迫性吸烟开始或维持以及戒烟和保持戒烟状态难度的生理因素。
