Synthetic Cannabinoids (UR-144/XLR-11)

Synthetic cannabinoids are chemical compounds that mimic the effects of THC, the main ingredient of cannabis. They bind to the cannabinoid receptors in the brain and were developed to treat pain. The two most common synthetic cannabinoids were JWH-018 and JWH-073. Four weeks after prohibition, second generation products were flooding the market.

New versions of these include AM-1248, AKB-48, UR-144 and XLR-11. UR-144 and XLR-11 are the new generation of synthetic cannabinoids and are chemically different to the first generation. New generations of synthetic cannabinoids are continuously emerging to replace the synthetic cannabinoids that have been made illegal.
