Hallucinogens are a class of drugs that cause you to experience visual and auditory hallucinations, mood changes, and more.[1] Some of the most commonly known hallucinogens are LSD, psilocybin mushrooms, and Salvia. While many hallucinogens come from naturally occurring plants, some are man-made in a lab.

Man-made hallucinogens are considered synthetic drugs. While LSD is a popular synthetic hallucinogen, there is another one that has been rising in popularity in recent years. Known as “2C-B,” this drug can be incredibly dangerous to abuse.

2C-B or (4-Bromo-2,5-dimethoxyphenethylamine) is known to cause effects similar to a mixture of LSD and MDMA. As a psychedelic drug, it could lead to hallucinations and changes in sensory perception. You could also experience stimulating effects when abusing 2C-B.

Unfortunately, taking a dose of 2C-B can lead to dangers and health risks. For example, you could develop psychosis or a condition known as hallucinogen-persisting perception disorder (HPPD).

What is 2C-B and What Effects Does it Cause?

2C-B is a synthetic hallucinogen that is often referred to as a club drug. Because it causes similar effects to a combination of LSD and MDMA, people like to abuse it when they attend clubs, raves, or music festivals. Unfortunately, because it is synthetic and relatively new, the long-term effects of 2C-B aren’t widely known.

2C-B may cause a variety of side effects, including:[2]

  • Dry mouth and dehydration
  • Increased energy and sweating
  • Increased blood pressure and heart rate
  • Nausea and vomiting
  • Dizziness and drowsiness
  • Increased confidence
  • Euphoria and elation
  • Anxiety and panic
  • Changes in perception
  • Confusion
  • Increased libido
  • Visual, auditory, and tactile hallucinations
  • Delusions and paranoia
  • Insomnia or sleep disturbances

The DEA reports that you experience different drug side effects depending on the dose of 2C-B you take.[2] For example, 4 mg causes you to be passive, and relaxed and experience slight sensory perception or emotional changes. On the other hand, higher doses can produce LSD-like hallucinations, delusions, psychosis, and even violent behavior.

Can You Get Addicted to 2C-B?

There is little research on whether 2C-B abuse leads to addiction. That said, you’ll likely develop a dependence on it the longer you abuse it. Most people who abuse 2C-B report experiencing a “crash” once the drug wears off, which could cause you to begin binging on the drug to avoid unwanted side effects.

The signs of 2C-B addiction include:

  • Taking 2C-B longer or in higher doses than you intended to
  • Spending a lot of time obtaining, using, or recovering from the use of 2C-B
  • Experiencing urges or cravings to abuse 2C-B
  • Failing to meet responsibilities at home, school, or work due to 2C-B use
  • Losing interest in previously enjoyed activities to have more time to abuse 2C-B
  • Continuing to use 2C-B despite experiencing social problems and physical or mental health issues as a direct result
  • Using 2C-B in risky situations, such as while driving
  • Needing to increase your dose of 2C-B to experience the desired effect
  • Dealing with withdrawal symptoms when you stop using 2C-B

If you think you’ve developed an addiction to 2C-B, it’s time to seek professional help. Long-term abuse of 2C-B can lead to health problems. Attending a drug rehab center reduces the risk of developing a wide range of long-term effects.

What are the Dangers of 2C-B?

While you might want to try 2C-B to experience psychedelic effects, it is best to avoid this substance. Because there is little research on the drug, the long-term effects aren’t well-known. Abusing it could lead to unknown health problems, addiction, and even overdose.

Some of the dangers associated with abusing 2C-B include:

  • Substance use disorder
  • Mood disturbances
  • Cognition and memory issues
  • Brain damage from substance abuse
  • Violent behavior and paranoia
  • Psychosis
  • Hallucinogen persisting perception disorder (HPPD)

In a study completed by the National Library of Medicine (NLM), symptoms were evaluated among patients who came to the hospital after consuming 2C-B. They experienced “mydriasis, agitation or aggression, hallucinations, confusion, anxiety, hypertension, and tachycardia.”[3]
