What factors predict the passage of state‐level e‐cigarette regulations?
研究了2007至2016年间美国各州电子烟法规的影响因素，发现较不保守的州更可能监管电子烟，而烟草游说力量强的州则更不可能。
E-cigarettes are controversial products. They may help addicted smokers to consume nicotine in a less harmful manner or to quit tobacco cigarettes entirely, but these products may also entice youth into smoking. This controversy complicates e-cigarette regulation as any regulation may lead to health improvements for some populations, and health declines for other populations. Using data from 2007 to 2016, we examine factors that are plausibly linked with U.S. state e-cigarette regulations. We find that less conservative states are more likely to regulate e-cigarettes and that states with stronger tobacco lobbies are less likely to regulate e-cigarettes. This information can help policymakers as they determine how best to promote public health through regulation.
