Summary

MDMB-CHMICA, classified as an indole-based synthetic cannabinoid, exhibits robust agonistic activity toward the CB1 receptor and has been commercialized online as a designer drug. Notably, while it was initially available under the name “MMB-CHMINACA,” the version corresponding to this codename (distinguished by the presence of isopropyl instead of t-butyl) emerged as AMB-CHMINACA in the designer drug market in 2015.

Chemistry

Analysis of MDMB-CHMICA revealed that numerous commercial samples exclusively contained the (S)-enantiomer, as determined through vibrational and electronic circular dichroism spectroscopy and X-ray crystallography. This (S)-configuration within the tert-leucinate group is unsurprising, considering that MDMB-CHMICA is likely synthesized using the more readily available and cost-effective “L” form of the tert-leucinate reactant.

Pharmacology:

MDMB-CHMICA functions as a highly potent full agonist of the CB1 receptor, boasting an efficacy of 94% and an EC50 value of 0.14 nM. This EC50 value is notably lower than that of JWH-018 (1.13 nM) and AB-CHMINACA (0.27 nM).

Metabolism

The primary metabolic reactions of MDMB-CHMICA involve mono-hydroxylations and hydrolysis of the carboxylic ester function. In total, 31 distinct metabolites have been identified in vivo.

Side Effects

MDMB-CHMICA has been associated with seventy-one serious adverse events, including 42 acute intoxications and 29 fatalities across nine European countries between 2014 and 2016. These adverse events encompassed a wide range of symptoms, including unconsciousness, nausea, seizures, tachycardia, and severe behavioural disturbances, among others.

Legal Status

MDMB-CHMICA is classified as a Schedule I controlled substance in the United States. It is illegal in various countries and regions, including Austria, Canada, China, Croatia, Denmark, and more.

In August 2016, the European Commission proposed a ban on MDMB-CHMICA throughout the European Union. On 27 February 2017, the Commission implemented this ban, requiring Member States to institute control measures and criminal penalties by no later than 4 March 2018.

Seizures

Between 2014 and 2016, over 3,600 seizures of MDMB-CHMICA were reported in 19 European Union member states. One notable seizure included 40 kg of the substance in Luxembourg in December 2014.
