I agree with this and have been told the same years ago when I was going to apply for a CBW permit to acquire a few porosus. I forget who was in charge then, maybe the fellow you mention, but he said I didn't need to bother with a CBW permit. This has been confirmed by a few dealers in FL as well. I see salts for sale in the classifieds as Fl sales only though. I can see where people can get confused.
