JWH-138 (THC-Octyl, Δ⁸-THC-C8) is a synthetic cannabinoid first synthesised by John W. Huffman, with a K_i of 8.5nM at the CB₁ cannabinoid receptor.^[1]

Isomers[edit]

Δ³-THC-C8

Δ⁹-THC-C8, CAS# 2552798-63-5

The Δ³/Δ^6a(10a) isomer was synthesised in 1941, but was found to be slightly less active than Δ³-THC itself.^[2] The alternate isomer Δ⁹-THC-C8 has also been synthesised,^[3] but has not been identified as a natural product.
