I find much to agree with in Hanson's writings, but in this case I just don't find him convincing.

His interpretation, or his evidence? I point this out because it looks to me like your position has shifted from "the smoking / lung cancer link is established by RCTs in animals" to "even though RCTs don't establish the smoking / lung cancer link for animals, we have other reasons to believe in the smoking / lung cancer link for humans."
