MMB-FUBICA is primarily used in research settings to study the effects of synthetic cannabinoids on the endocannabinoid system. Its application is focused on understanding the binding affinity and activity at cannabinoid receptors, particularly CB1 and CB2, which helps in exploring the pharmacological and toxicological profiles of similar compounds. Researchers utilize it to investigate potential therapeutic effects or risks associated with synthetic cannabinoids, contributing to the development of safer drugs or regulatory measures. It is not intended for human or veterinary use due to its potent and unpredictable effects.
