Waterpipe tobacco package labelling typically indicates "0.0% tar" and "0.05% or 0.5% nicotine".
To determine the extent to which nicotine labeling is related to nicotine delivery.
110 waterpipe smokers engaged in a 45-minute waterpipe smoking session. Puff topography and plasma nicotine were measured. Three waterpipe tobacco brands were used: Nakhla (0.5% nicotine), Starbuzz (0.05% nicotine), and Al Fakher (0.05% nicotine). Data were analyzed by one-way ANOVA.
Topography did not differ across brands. Peak plasma nicotine varied significantly across brands. Al Fakher had the highest nicotine delivery (11.4 ng/ml) followed by Nakhla (9.8 ng/ml) and Starbuzz (5.8 ng/ml).
Nicotine labelling on waterpipe tobacco products does not reflect delivery; smoking a brand with a "0.05% nicotine" label led to greater plasma nicotine levels than smoking a brand with a "0.5% nicotine" label. Waterpipe tobacco products should be labelled in a manner that does not mislead consumers.
水烟烟草包装标签通常表明“0.0%焦油”和“0.05%或 0.5%尼古丁”。
确定尼古丁标签与尼古丁释放之间的关联程度。
110 名水烟吸烟者进行了 45 分钟的水烟吸烟。测量吸烟地形和血浆尼古丁。使用了三种水烟烟草品牌:Nakhla(0.5%尼古丁)、Starbuzz(0.05%尼古丁)和 Al Fakher(0.05%尼古丁)。通过单向方差分析进行数据分析。
不同品牌之间的地形没有差异。品牌之间的血浆尼古丁峰值差异显著。Al Fakher 的尼古丁释放量最高(11.4ng/ml),其次是 Nakhla(9.8ng/ml)和 Starbuzz(5.8ng/ml)。
水烟烟草制品上的尼古丁标签不能反映释放量;吸食标有“0.05%尼古丁”标签的品牌比吸食标有“0.5%尼古丁”标签的品牌导致更高的血浆尼古丁水平。水烟烟草制品的标签应使消费者不易产生误解。
