25C-NBOMe is a psychedelic drug and derivative of the psychedelic phenethylamine2C-C. 25C-NBOMe appeared on online vendor sites in 2010 but was not reported in the literature until 2011. It acts as a potent agonist for the 5HT2Areceptor, and has been studied in its 11C radiolabelled form as a potential ligand for mapping the distribution of 5-HT2A receptors in the brain, using positron emission tomography.
History
25C-NBOMe is derived from the psychedelic phenethylamine 2C-C by substitution on the amine with a 2-methoxybenzyl group. 25C-NBOMe is a clumpy white powder with a notably bitter and metallic taste. 25C-NBOMe has been found on blotter mimics sold as LSD.
Dosage
Anecdotal reports from human users suggest 25C-NBOMe to be an active hallucinogen at a dose of as little as 200-500 µginsufflated and 300-600 µg buccally, making it only half to a third the potency of LSD. NBOMe-substituted compounds have a diminished absorption rate passing through mucus membranes, but generally remain inactive when taken orally. Buccal, sublingual or insufflated routes of administration are all viable options. Absorption rate buccally and sublingually can be increased when complexed with HPBCD complexing sugar, however the most efficient is nasal administration, which shortens the duration while increasing intensity, but has been attributed to several overdoses due to improper dosing.
Effects
Desired
strong open- and closed-eye visuals, including trails, color shifts, brightening, etc.
25C-NBOMe overdoses have been linked to multi-organ failure. It is a substituted para-Chloroamphetamine which is a known neurotoxin, 25C-NBOMe being much more potent and a direct serotonergic neurotoxic agent.
25C-NBOMe was sold as a designer drug in New Zealand in early 2012, but was withdrawn from sale after a statement by Associate Health Minister Peter Dunne that 25C-NBOMe would be considered to be substantially similar in chemical structure to the illegal hallucinogen DOB, and was therefore a Class C controlled drug analogue.
Russia
Russia became the first country to regulate the NBOME class. The entire NBOMe series of psychoactives became controlled in the Russian Federation starting October, 2011.
Sweden
added 25C-NBOMe to schedule I as narcotics in Sweden as of Aug 1, 2013, published by Medical Products Agency in their regulation LVFS 2013:15 listed as 25C-NBOMe 2--N-etanamin.
Several NBOMe series compounds will be temporarily scheduled in the United States for 2 years. The temporary scheduling applies to 25C-NBOMe, 25B-NBOMe, and 25I-NBOMe. In November 2015, the temporary scheduling was extended for another year.
China
As of October 2015 25C-NBOMe is a controlled substance in China.
