Products ranging from tinctures to gummy bears containing a hemp byproduct with euphoric THC effects are legal and for sale all around Indiana, where the purchase and use of traditional marijuana violates the law.
Delta 8 THC products abound, available at CBD stores, smoking supply shops and even gas stations. While some states regulate or ban the sale of delta 8 tetrahydrocannabinol, Indiana is one of 30, from Maine to Wyoming, that has no limitations on the hemp-derived compound.
A federal law that prohibits what's called delta 9 THC leaves the less-potent delta 8 unregulated. The 2018 American Farm Bill that legalized hemp defines it as a cannabis plant that contains 0.3% or less delta-9 THC. It doesn't mention delta 8, which is less potent.
