THC-O produces psychedelic hallucinations at higher doses, but THCP does not. Both can help you sleep, ease pain, and relax. THCP is more psychoactive than THC-O because its alkyl side chain is longer. THCP has seven bonds, while THC-O has only five.
The alkyl side chain, sometimes called the “backbone” or “main chain”, determines how a cannabinoid interacts with the body's receptors, especially with the cannabinoid receptors. THCP is more potent than THC-O due to the length of its alkyl side chain. THCP has a seven-link alkyl side chain, while THC-O has a five-link alkyl side chain.
