FOR MICROSCOPY AND TAXONOMY USE ONLY. Psilocybin mushroom spores are legal to possess in most U.S. states because they do not contain psilocybin or psilocin, the federally controlled psychoactive compounds. However, Georgia and Idaho have prohibited the possession, sale, or research of psilocybin mushroom spores regardless of intent. As a result, we do not accept sales or orders of swabs and/or spore prints from these states.
