What is 2C-B?
2C-B (4-bromo-2,5-dimethoxyphenethylamine) is a synthetic psychedelic substance derived from mescaline. It was invented in 1974 by a man named Alexander Shulgin. It’s effects have been described as a combination between LSD and MDMA — but this is a simplification. In reality, the experience is entirely unique.
What’s The Dose of 2C-B?
The dosage range for 2C-B is between 5 mg and 35 mg. Most tablets contain 5 mg of 2C-B each.
The dosage range of 2C-B includes:
- 1 mg — Microdose
- 5 mg — Threshold dose (stimulant-like effects)
- 5–20 mg — Standard psychoactive dose (hallucinogenic & stimulant effects)
- 20–35 mg — High psychedelic dose (strong hallucinogenic & stimulant action)
- 35–60 mg — Heroic dose (unpredictable effects, not recommended)
It has a high level of safety. Shulgin, the inventor of the drug, reportedly took 100 mg by accident. This is a dose nearly three times what’s considered a high dose for the substance. He didn’t suffer any severe side effects from the experience.
With that said, higher doses can be intense. Most people who use more than 35 or 40 mg of the drug report intense, often scary, or confronting hallucinations.
The higher the dose, the stronger the visuals. Some could even describe the visuals at higher doses to be “cartoon-like,” — which is similar to the visuals experienced with higher doses of mescaline.
What Does 2C-B Feel Like?
The effects of 2C-B could be described as a combination of MDMA and LSD.
While there’s truth to this, it’s not perfectly accurate. It has empathogenic effects like MDMA and hallucinogenic effects like LSD. But the experience is unique in and of itself. The overall effects of 2C-B share much more resemblance to mescaline.
As part of our ongoing experience surveys, we ask you to share their experiences to better understand the effects and common dosages of substances.
Many people taking part in our surveys and in the psychedelic community at large consider it to be their favorite psychedelic.
How Long Does it Last?
2C-B usually lasts between 4 and 8 hours.
The effects usually begin to appear within about 45 minutes to an hour after taking it and peak around the 2-hour mark.
Peak effects last between 1 and 2 hours before tapering off. The comedown on 2C-B is very slow and gradual — which is considered one of the advantages of this substance. Most amphetamines or other stimulants tend to produce a rapid comedown — which can make users feel depressed. 2C-B is much more gradual and gentle.
