In low doses, 2C-B’s effects are similar to those of MDMA (empathy, affection, etc.) and as the doses increase, the effects become more hallucinatory and similar to LSD. Most users experience euphoria, visual hallucinations and increased libido. Many users experience abnormal fits of laughter and smiling. At high doses, users report seeing cartoon characters both with eyes closed and open.
When swallowed or snorted, 2C-B takes effect within 45-60 minutes and lasts about 4 hours on average. It stimulates the serotonin mechanism and according to some studies, it may slightly increase dopamine levels.
2C-B’s side effects include muscle spasm, tremors, abdominal pain, nausea and diarrhea. With doses exceeding 30 mg, many users report frightening hallucinations, rapid heartbeat, heartburn and hyperthermia.
