MDMB-CHMICA (also incorrectly known as MMB-CHMINACA) is an indole-based synthetic cannabinoid that is a potent agonist of the CB1 receptor and has been sold online as a designer drug.[1][2] Ironically while MDMB-CHMICA was initially sold under the name "MMB-CHMINACA", the compound corresponding to this code name (i.e. the isopropyl instead of t-butyl analogue of MDMB-CHMINACA) has never been identified on the designer drug market as of 2015.[3]

40 kg of MDMB-CHMICA was seized in Luxembourg in December 2014.[4]

Side Effects

There have been a number of reported cases of deaths and hospitalizations in relation to this synthetic cannabinoid.[5][6][7][8]


MDMB-CHMICA appears to have a similar metabolic fate as AB-CHMINACA.[9]

Legal status

As of October 29, 2014 the state of Louisiana emergency scheduled MDMB-CHMICA into Schedule I.[10]

MDMB-CHMICA falls into Anlage II of the Neue Psychoaktive Substanzen Gesetz (NPSG) and is therefore illegal in Austria.[11]

Germany's Sachverständigenausschuss für Betäubungsmittel suggested banning MDMB-CHMICA as a Anlage II controlled drug on 17 April 2015.[12]

Sweden's public health agency suggested classifying MDMB-CHMICA as hazardous substance on November 10, 2014.[13]

As of October 2015 MDMB-CHMICA is a controlled substance in China.[14]
