We examined differences between nicotine concentrations and pH in cigarette and cigar tobacco filler.
Nicotine and pH levels for 50 cigarette and 75 cigar brands were measured. Non-mentholated and mentholated cigarette products were included in the analysis along with several cigar types as identified by the manufacturer: large cigars, pipe tobacco cigars, cigarillos, mini cigarillos, and little cigars.
There were significant differences found between pH and nicotine for cigarette and cigar tobacco products. Mean nicotine concentrations in cigarettes (19.2 mg/g) and large cigars (15.4 mg/g) were higher than the other cigars types, especially the pipe tobacco cigars (8.79 mg/g). The mean pH for cigarettes was pH 5.46. Large cigars had the highest mean pH value (pH 6.10) and pipe tobacco cigars had the lowest (pH 5.05).
Although cigarettes are the most common combustible tobacco product used worldwide, cigar use remains popular. Our research provides a means to investigate the possibility of distinguishing the 2 tobacco product types and offers information on nicotine and pH across a wide range of cigarette and cigar varieties that may be beneficial to help establish tobacco policies and regulations across product types.
我们研究了卷烟和雪茄烟丝中尼古丁浓度和pH值的差异。
测量了50个卷烟品牌和75个雪茄品牌的尼古丁和pH值水平。分析中纳入了非薄荷醇和薄荷醇卷烟产品以及制造商确定的几种雪茄类型:大雪茄、斗烟雪茄、小雪茄、迷你小雪茄和小雪茄。
卷烟和雪茄烟产品的pH值和尼古丁之间存在显著差异。卷烟(19.2毫克/克)和大雪茄(15.4毫克/克)中的平均尼古丁浓度高于其他雪茄类型,尤其是斗烟雪茄(8.79毫克/克)。卷烟的平均pH值为5.46。大雪茄的平均pH值最高(6.10),斗烟雪茄的平均pH值最低(5.05)。
尽管卷烟是全球使用最普遍的可燃烟草产品,但雪茄的使用仍然很受欢迎。我们的研究提供了一种方法来调查区分这两种烟草产品类型的可能性,并提供了有关广泛的卷烟和雪茄品种中尼古丁和pH值的信息,这可能有助于制定跨产品类型的烟草政策和法规。
