White subjects took significantly more puffs of cigarette smoke before stopping than did black subjects in a modified, controlled-dose rapid smoking procedure. Paradoxically, however, no racial differences were detected for changes in carbon monoxide levels, or changes in cardiovascular variables (systolic and diastolic blood pressure, and heart rate). Due to the cooling and topical anesthetic properties of menthol, it was hypothesized that menthol and regular cigarette smokers would take more puffs from menthol cigarettes than from regular cigarettes before stopping in the controlled-dose rapid smoking procedure. However, no difference was observed for the number of puffs taken from regular as opposed to menthol cigarettes (cigarette type condition) and no differences were found for Cigarette Preference (regular smokers vs. menthol smokers).
在一种改良的、控制剂量的快速吸烟程序中，白人受试者在停止吸烟前吸入的香烟烟雾量明显多于黑人受试者。然而，矛盾的是，在一氧化碳水平变化或心血管变量（收缩压和舒张压以及心率）变化方面未检测到种族差异。由于薄荷醇具有冷却和局部麻醉特性，因此推测在控制剂量的快速吸烟程序中，薄荷醇香烟吸烟者和普通香烟吸烟者在停止吸烟前从薄荷醇香烟中吸入的烟雾量会比从普通香烟中吸入的更多。然而，在从普通香烟与薄荷醇香烟吸入的烟雾量（香烟类型条件）方面未观察到差异，并且在香烟偏好方面（普通吸烟者与薄荷醇吸烟者）也未发现差异。
