2C-B

2C-B (4-Bromo-2,5-dimethoxyphenethylamine) is a psychedelic drug of the 2C family. It was first synthesized by Alexander Shulgin in 1974. In Shulgin's book PiHKAL, the dosage range is listed as 12–24 mg.[2] As a recreational drug, 2C-B is sold as a white powder sometimes pressed in tablets or gel caps.[3] It is also referred to by a number of street names.[4] The drug is usually taken orally, but can also be insufflated or vaporized. While being primarily a psychedelic it is also a mild entactogen.[2]
