MDMB-CHMICA, a synthetic cannabinoid receptor agonist found in recreational drug products across Europe since August 2014, is widely available from online suppliers. A systematic review of scientific literature and Internet sources identified 78 websites selling it, with prices decreasing for larger quantities. User reports on discussion forums from October 2014 onward described euphoria as the most common positive effect (30.6% of 36 reports), but almost all reports (91.7%) mentioned adverse effects, most frequently palpitations (30.6%), vomiting (25.0%), loss of consciousness (16.7%), visual hallucinations (16.7%), chest pain (13.9%), and anxiety (13.9%). Published literature includes two case reports of fatalities and one series of analytically confirmed intoxications. Both users and suppliers warn of its high potency.
