MN 18 is an indazole-based synthetic cannabinoid that is an agonist for the cannabinoid receptors, with K_i values of 45.72 nM at CB₁ and 11.098 nM at CB₂ and EC₅₀ values of 2.028 nM at CB₁ and 1.233 nM at CB₂,^[1] and has been sold online as a designer drug.^[2]^[3] It is the indazole core analogue of NNE1. Given the known metabolic liberation (and presence as an impurity) of amantadine in the related compound APINACA, it is suspected that metabolic hydrolysis of the amide group of MN-18 may release 1-naphthylamine, a known carcinogen. MN-18 metabolism has been described in literature.^[4]^[5]

Legal status

MN-18 is banned in Sweden.^[when?]^[6] On 15 September 2014 the Turkey government banned the sale of MN-18.^[7]
