Some of the researchers and advocates who opposed our crowdfunding campaign to raise money for a randomized behavioral study of the effects of electronic cigarettes on smoking behavior argued that randomized clinical trials (RCTs) are simply not appropriate to study e-cigarettes because they cannot simulate the real-life situation, where smokers have many choices of different types of products, can engage with social networks, and can experiment over time, change products, advance from one type of product to another, etc.

If it were a public health policy based on some sort of health principles, then it certainly would not penalize ex-smokers who quit using electronic cigarettes. In contrast, it would actually reward these individuals for having quit smoking and perhaps saved their lives.
