Is it illegal to falsely advertise for something illegal?

In Ohio they could be charged with counterfeit controlled substances, promoting and encouraging drug abuse, or fraudulent drug advertising, all of which are low-level felonies. See Revised Code 2925.37. When I was a prosecutor I sometimes saw mooks who sold acorn meats and called it crack cocaine, oregano and called it marijuana, or talcum powder or baby formula and called it powder cocaine.
