The 2C family is a group of synthetic psychedelics used as designer drugs and MDMA analogs. They were first synthesized by chemist Alexander Shulgin in the 1970s. Since then they have been used to circumvent legal bans on MDMA. Many members of the group, like 2C-I and 2C-B cause stimulation, euphoria, increased heart rate, color enhancement, and hallucinations. Different members of the 2C family have different effective doses, and they can be hard to tell apart. This can lead to overdose in cases of mistaken identity.
