Which part of the US Constitution gives the Feds the power to ban a naturally occurring substance??

You mean naturally occurring substances like Uranium, Anthrax, Chlorine gas, and other dangers things? Why that would be the defense clause which is an umbrella authorization for anything which threatens the lives of citizens.

It authorizes the Federal government to ban chemical and biological weapons, which is what drugs are.

Statements like that are a public embarrassment to this site.
