NM-2201 (also known as CBL-2201 and NA-5F-PIC[1]) is an indole-based synthetic cannabinoid that presumably has similar properties to the closely related 5F-PB-22 and NNE1, which are both full agonists and unselectively bind to CB1 and CB2 receptors with low nanomolar affinity.[2][3][4][5]


NM-2201 acts as a full agonist with a binding affinity of 0.332 nM at CB1 and 0.732 nM at CB2 cannabinoid receptors.[6] It has been linked to serious adverse events in users.[7]

Legal status[edit]

NM-2201 is specifically banned in Sweden,[8] Germany (Anlage II),[9] and Japan[10] but is also controlled in many other jurisdictions under analogue laws.

On May 30, 2018 the United States Drug Enforcement Administration, Department of Justice published a notice of intent to place NM-2201 and 4 other synthetic cannabinoids in schedule I of the Controlled Substances Act. This notice went into effect on June 29, 2018.[11]


NM-2201 was linked to an incident in December 2015 where 25-30 people in Ocala, FL were taken to hospitals after experiencing seizures.[11]
