Dual use of e-cigarettes and cigarettes is common among young adults. Earlier research has used an internet panel to assess anticipated effects of eliminating nicotine, flavors (except menthol), and customizable e-cigarettes on predicted changes in e-cigarette and cigarette consumption. This earlier analysis showed that all these policies were predicted to lower e-cigarette consumption and increase cigarette consumption among these dual users. The earlier analysis, did not, however, estimate the effect of these policies considering both lowered and increased consumption. We computed the net effects of these policies as the difference between people predicting quitting or using cigarettes less and those predicting that they would use them more. The same calculations were done for e-cigarettes. Significance testing was done with -tests. As expected, the net effect of all three policies was to significantly lower e-cigarette consumption. The net effect was to also lower cigarette consumption for eliminating nicotine and flavors in e-cigarettes, with no significant net effect of eliminating modifiable e-cigarettes. Eliminating nicotine and flavors from e-cigarettes is predicted to lower cigarette as well as e-cigarette consumption.
电子烟和香烟的双重使用在年轻人中很常见。早期的研究使用互联网面板来评估消除尼古丁、口味（除薄荷醇外）和可定制电子烟对电子烟和香烟消费预测变化的预期影响。早期的分析表明，所有这些政策都预计会降低电子烟的消费，并增加这些双重使用者对香烟的消费。然而，早期的分析并没有估计这些政策在考虑到降低和增加消费的情况下的效果。我们通过计算那些预测戒烟或使用香烟较少的人和那些预测使用更多的人的差异，来计算这些政策的净效应。对电子烟也进行了同样的计算。采用 t 检验进行显著性检验。不出所料，所有三种政策的净效应都是显著降低电子烟的消费。在电子烟中消除尼古丁和口味的净效应也降低了香烟的消费，而消除可调节电子烟则没有显著的净效应。从电子烟中消除尼古丁和口味预计会降低香烟和电子烟的消费。
