2C-B is a synthetic psychedelic of the phenethylamine class and perhaps the most well-known member of the 2C-x family, which are structurally related to mescaline. First synthesized by Alexander Shulgin in 1974, it initially saw use as an aid in psychiatric therapy. 2C-B is characterized by warm, colorful visuals, mild entactogenic qualities, and a prominent body component. It is generally considered more manageable than classical psychedelics like LSD or psilocybin, though it is notably dose-sensitive.
