Key Aspects of 2C-B:
- Form:Â The mention of “Mario Heads” likely refers to a specific pill press design, a common method for illicit pill identification. “HBr” (Hydrobromic acid) indicates the salt form, which is typical for these compounds.
- Effects:Â Users report energy, alertness, enhanced emotions, and a strong, sometimes overwhelming, visual experience. It can also produce empathogenic effects similar to MDMA, such as increased libido.
- Risks & Safety:Â 2C-B is classified as a Class A drug in the UK and a controlled substance in many regions. The margin between desired effects and adverse toxicity can be narrow. Common side effects include nausea, stomach cramps, and, at higher doses, intense anxiety or panic.
- Physiological Impact: 2C-B causes an increase in heart rate (HR), systolic blood pressure (SBP), and diastolic blood pressure (DBP), with maximum effects typically appearing 1–4 hours after ingestion.Â
