JWH-018 Powder is a synthetic cannabinoid that belongs to the family of chemicals known as aminoalkylindoles. It was originally developed in the 1990s by John W. Huffman, hence the name “JWH.” JWH-018 is designed to mimic the effects of THC (delta-9-tetrahydrocannabinol), the active compound found in cannabis. It is commonly sold and used as a recreational drug due to its psychoactive properties.
