As far as I know,,,, Nothing will happen if he is in an accident(god forbid)and tries to sue under your implication that it is dangerous. Do you have any data from the fda or a study from a university to prove your vague claim. None of it is fda regulated becouse there is no conflicting data IMO! Otherwise the fda would regulate it. Only after a few of the notable universities gave them the data from their comprehensive studies. What else ya got?
