I am an extremely pro-self-medication (implying every literate person should have basic medical education knowing how does their body function and how to maintain it optimally) and anti-scheduling person yet hell yeah I agree - people whom many people believe in, especially the officials like the freakin president should quadruple-check before saying anything what can be risky. Billions of people listen to him, a huge portion of them is not particularly bright, he should take that in account. Ideally it should be illegal for an official to say anything that is not scientifically correct.
