MDMB-CHMINACA[1] (also known as MDMB(N)-CHM) is an indazole-based synthetic cannabinoid that acts as a potent agonist of the CB1 receptor,[2] and has been sold online as a designer drug.[3][4][5][6][7] It was invented by Pfizer in 2008, and is one of the most potent cannabinoid agonists known, with a binding affinity of 0.0944 nM at CB1, and an EC50 of 0.330 nM.[8] It is closely related to MDMB-FUBINACA, which caused at least 1000 hospitalizations and 40 deaths in Russia as consequence of intoxication.[9]

Legal status

MDMB-CHMINACA is a Fifth Schedule of the Misuse of Drugs Act (MDA) controlled substance in Singapore as of May 2015.[10]

MDMB-CHMINACA is illegal in Germany, Switzerland as of December 2015.[11]

Sweden's public health agency suggested classifying MDMB-CHMINACA as a hazardous substance, on September 25, 2019.[12]
