A few states do, although most states don't regulate hypnotherapy. My understanding is that the licensing applies to one-on-one hypnotherapy services and wouldn't apply to hypnosis recordings created by a semi-automated process. Among my competitors who offer hypnosis recordings online (either pre-made or custom recorded), I don't see any of them restricting their sales to states without licensing requirements. Having said that, I appreciate your comment, and I think it's a good idea to double-check with my lawyer that everything I'm doing is kosher.
