Hey, not being in any way a smoker myself I sell primitive things at a farmers market. There are a lot of people in town who are vegans and the like who come to the market, thus I know that if I made up some handcrafted pipes and peace pipes I could sell them and am planning too. I was wondering though if it would be possible for me to gather any wild herbs that could be safely smoked in them and sold legally? I only know very little about this, like willow bark, sweetgrass, cedar bark... but I don't know where I would begin or what regulations usually are, I know I couldn't sell anything tobacco without a license. Any help on this would be great! Thanks.
