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.

And importantly, the same thing is being said today, in some hospitals, about smokers. A number of hospitals refuse to hire smokers not merely to reduce health care costs, but because they don't want their patients to have to even "see" a smoker.
