If you're implying publication bias, that's addressed by preregistration, though you either have to be careful about looking it up or else rely on meta-analysis.

Otherwise if they're publishing true results then there you go. Nicotine does have some benefits; it's basically the only effective nootropic and it's pretty effective for schizophrenia which is why almost all schizophrenic people are smokers. Of course the problem is it's super addictive and all the ways of taking it give you cancer.
