Acute side effects after consumption of the new synthetic cannabinoids AB-CHMINACA and MDMB-CHMICA

Abstract

In this study, the valine derivative AB-CHMINACA and the tert-leucine derivative MDMB-CHMICA ("third generation of SCs") seem to be associated with more severe clinical toxicity than was previously reported in patients exposed to earlier generation SCs such as JWH-018. However, this observation needs to be confirmed with a larger cohort of patients with analytically confirmed abuse of third generation SCs. The rapid turnover of SCs on the drug market together with the occurrence of SCs such as AB-CHMINACA and MDMB-CHMICA is alarming, especially because of the unexpectedly high frequency of neuropsychiatric symptoms.
