25E-NBOH (2C-E-NBOH, NBOH-2C-E) is a derivative of the phenethylamine derived hallucinogen 2C-E. It was first developed by Martin Hansen at the University of Copenhagen in 2010 as a brain imaging agent,^[2] but has subsequently been sold as a designer drug, first being identified in Brazil in 2018 on seized blotter paper,^[3]^[4]^[5] as well as in Slovenia ^[6] and France.^[7] It acts as a potent serotonin receptor agonist with similar affinity to better-known compounds such as 25I-NBOMe at 5-HT_2A and 5-HT_2C receptors.^[8]

Legal status
