Symptoms adolescents experience during their first time using a cigarette predict their current use, but little is known regarding the symptoms experienced during first e-cigarette use. We conducted a pilot study to understand the symptoms adolescents experience when they first tried cigarettes and e-cigarettes and the associations between these symptoms and current use. Participants were 41 adolescents in two U.S. cities who had tried cigarettes or e-cigarettes. We asked adolescents to recall the symptoms they experienced during their first cigarette or e-cigarette and categorized symptoms as negative (felt bad, coughing/chest pain, bad taste, upset stomach, dizzy/lightheaded) or positive (felt relaxed, rush/buzz). Adolescents reported fewer negative symptoms for first e-cigarette than first cigarette use (all < 0.05). Current cigarette smoking was associated with endorsing fewer negative symptoms (OR = 0.49, 95% CI = [0.25, 0.95]) and more positive symptoms (OR = 7.11, 95% CI = [1.47, 34.33]) at first cigarette use. First e-cigarette use symptoms were not associated with current e-cigarette use. Adolescents reported fewer negative symptoms from first e-cigarette than from first cigarette, and e-cigarette symptoms did not influence use as they do for cigarettes. Additional research is needed to confirm these findings in longitudinal studies.
青少年首次使用香烟时所经历的症状可预测其当前的使用情况，但对于首次使用电子烟时所经历的症状却知之甚少。我们开展了一项试点研究，以了解青少年首次尝试香烟和电子烟时所经历的症状，以及这些症状与当前使用情况之间的关联。参与者为美国两个城市的41名曾尝试过香烟或电子烟的青少年。我们要求青少年回忆他们首次使用香烟或电子烟时所经历的症状，并将症状分为负面症状（感觉不适、咳嗽/胸痛、味道不佳、胃部不适、头晕/眩晕）或正面症状（感觉放松、兴奋/有快感）。青少年报告称，首次使用电子烟时的负面症状比首次使用香烟时少（所有P<0.05）。当前吸烟与首次使用香烟时认可较少的负面症状（比值比=0.49，95%置信区间=[0.25, 0.95]）和较多的正面症状（比值比=7.11，95%置信区间=[1.47, 34.33]）相关。首次使用电子烟时的症状与当前使用电子烟的情况无关。青少年报告称，首次使用电子烟时的负面症状比首次使用香烟时少，并且电子烟症状对使用的影响与香烟不同。需要进一步的研究在纵向研究中证实这些发现。
