2C-B is a hallucinogenic drug first synthesised by Alexander Shulgin in 1974. Its effects are considered to be somewhere between those of LSD and MDMA and vary greatly depending on dose. 2C-B is available as powder, pills or capsules and is almost always taken orally due to how painful and intense it is to snort.

Effects | Dosage | Advice | Support


If taken orally, the effects of 2CB will take about 45 minutes to an hour to come on and will last from 4-8 hours (dose dependent).

  • Euphoria
  • Giggles
  • Visual and auditory hallucinations
  • Spiritual connection with the earth and other people
  • Enhanced sensory awareness (touch, sight, sound)
  • Increased libido
  • Increased energy
  • Distortion of time
  • Nausea/vomiting
  • Anxiety and paranoia
  • Insomnia


Dosage will depend on a number of factors including tolerance, gender and how it’s taken (either nasally or orally). This is a guide only.

  • Threshold - 2-5 mg
  • Light - 5-15 mg
  • Common - 15-25 mg
  • Strong - 25 mg +

2C-B is highly dose sensitive. Lower doses will be more MDMA-like, higher doses will produce a full psychedelic experience.  Taking doses over 25 mg will greatly increase the risk of having a bad trip.

Harm Reduction Advice

  • If you have access to powder 2C-B, always weigh your dose with a milligram scale. A 15mg dose will produce a very different experience to a 30mg dose and it is not possible to measure this just by looking at two piles of powder.
  • Consider your set and setting. If you’re feeling worried/anxious/depressed or you’re not in a pleasant environment its probably best to save your drugs for another day when you’re more likely to have a fun experience.
  • If you’re having a bad trip, remind yourself you have taken a drug and that the effects will wear off soon.
  • Consider having a 'trip sitter', someone who remains sober and can help out if someone is having a bad time.
  • If someone can’t be 'talked down' from a bad trip, consider seeking medical assistance.
  • Don’t snort 2C-B as it is incredibly painful and damaging to your nose. You’ll also start tripping almost immediately which isn’t ideal if you’re in the midst of a massive nose bleed.
  • Be mindful that 2C-B has some stimulant properties so make sure you drink plenty of water and if you’re dancing make sure you take break so you don’t overheat.
  • Do not attempt to get in the car and drive. Make sure you find a safe alternative.
