THCp is tetrahydrocannabiphorol, another chemical cousin of regular Delta 9 THC. In contrast to THCa, THCp is psychoactive and can get you high. Because of an elongated carbon side chain, it sets itself apart from the main compound, and that small difference can cause unique effects. THCp provides its users with an intense, relaxing high. Its effects are long-lasting, perfect for the ultimate disconnect. It has sedative effects, and many users report using it to replace their prescription sleep medications.
