Clemson researchers look to salvage IP rights to THC compounds

JWH-133, the best of the THC compounds, is unpatentable due to prior publication.

Huffman's research, however, centers on THC's bonding with the CB2 receptor, which was discovered in 1993 and is part of the immune system. Huffman and five colleagues work together in Hunter Laboratory creating compounds that also bond with the CB2. Huffman's compounds differ from THC and its synthetic cousin Marinol because they do not bond with the CB1; they do not produce a high or an increase in appetite.
