2C-B

2C-B, also known as 4-bromo-2,5-dimethoxyphenethylamine or by names such as Nexus or Erox, is a psychedelic drug of the phenethylamine and 2C families. The drug is used as a recreational drug and is usually taken orally. 2C-B produces hallucinogenic, mild stimulant, and mild entactogenic-like effects. Its hallucinogenic effects at typical doses are milder than those of other psychedelics like LSD or psilocybin. The drug acts as a potent partial agonist of the serotonin 5-HT2 receptors, including of the serotonin 5-HT2A receptor. It produces psychedelic-like effects in animals. Numerous analogues and derivatives of 2C-B are known, such as DOB, 2C-B-FLY, and 25B-NBOMe among others. 2C-B was developed by Alexander Shulgin in 1974 and was described by him in the scientific literature in 1975. The drug emerged as a novel recreational designer drug and MDMA (ecstasy) substitute in the mid-1980s. Subsequently, it became a controlled substance in the United States in the mid-1990s. 2C-B was one of the first 2C psychedelics to be described. It is the most popular and well-known of the 2C psychedelics and is one of the most widely used designer drugs.
