"“There’s so much we don’t yet know about e-cigarettes,” said Douglas Tipperman, M.S.W., a public health advisor at SAMHSA. “They are not harmless. We don’t know the health impact at the individual or the population level.”

What this indicates is that this is not simply junk science. Rather, it is a deliberate attempt on the part of the investigators to misuse data. They are using these data to draw a conclusion about whether electronic cigarettes are effective in helping smokers quit, yet they are knowingly drawing upon data from smokers who are using e-cigarettes for other reasons, who may have simply tried an electronic cigarette once, and who most definitely were not using these products as part of a current quit attempt.
