2C-B

How is 2C-B used?

2C-B is usually taken via the mouth (orally). 2C-B can be snorted, but anecdotal reports suggest this method of use can be very painful.⁴

Effects of 2C-B

Use of any drug can have risks. It’s important to be careful when taking any type of drug.

Psychedelics affect everyone differently, based on:

• size, weight and health
• whether the person is used to taking it
• whether other drugs are taken around the same time
• the amount taken
• the strength of the drug (varies from batch to batch)
• environment (where the drug is taken).

2C-B affects everyone differently, but effects may include:

• dry mouth
• increased blood pressure and heart rate
• nausea and vomiting
• dizziness
• drowsiness
• confidence
• euphoria
• feelings of well-being
• anxiety and panic
• change in perception
• hearing sounds
• confusion
• sexual arousal
• hallucinations
• insomnia.^{2, 4}

The effects of 2C-B typically last from four to eight hours. There have been anecdotal reports it can last for up to 12 hours.³

Impact of mood and environment

Drugs that affect a person’s mental state (psychoactive drugs) can also have varied effects depending on a person’s mood (often called the ‘set’) or the environment they’re in (the ‘setting’).

Set is a person’s state of mind, previous encounters with psychedelic drugs, and expectations of what’s going to happen. For example, feelings of stress or anxiety before using 2C-B may result in an unpleasant experience (bad trip).⁵

Setting is the environment in which someone consumes 2C-B – whether it’s known and familiar, who they’re with, if they’re indoors or outdoors, the type of music and light. For example, using 2C-B in a calm, quiet and relaxed environment could lead or contribute to a pleasant experience but being in a noisy, crowded place may result in a negative experience.⁵

Being in a good state of mind, with trusted friends and a safe environment before taking 2C-B reduces the risk of having a ‘bad’ trip.

Overdose

There have been no reported deaths from 2C-B, but deaths have occurred from the use of other 2C drugs.²

Coming down 

According to anecdotal user reports, the after-effects or comedown of taking 2C-B can last for around 2-4 hours.³

Long-term effects

To our best knowledge, there have been no scientific studies into the long-term effects of 2C-B use.

2C-B and mental health 

People with a family history of mental illness are more likely to experience anxiety or paranoia after using 2C-B. This is consistent with what the evidence tells us about people with mental illness and psychedelic use.⁶

Bad trips 

Some people may have negative experiences taking psychedelics, or experiences they find challenging. This can include experiencing:

• frightening or confronting hallucinations
• intense anxiety and confusion
• fear and paranoia.^{5, 7}

Tolerance and dependence

Similar to other psychedelics, 2C-B does not produce dependence. Some people that use 2C-B report a tolerance to it after regular use (more than once every five to seven days).³

Mixing 2C-B with other drugs 

The effects of taking 2C-B with other drugs − including over-the-counter or prescribed medications − can be unpredictable and dangerous.

2C-B + cannabis = a more intense psychedelic experience which could result in anxiety and increase the chances of having a ‘bad trip’.⁸

2C-B + tramadol = a lowering of the seizure threshold. May cause seizures in predisposed individuals.^{9, 10}

Reducing harm

• Start with a lower dose until you know how the drug affects you personally. It will be different for everyone due to factors such as weight, tolerance and metabolism.
• Always weigh the 2C-B before use, using a milligram scale. A 15mg dose will produce a very different experience to a 30mg dose.
• Consider the impact of mood and environment.
• Consider having a person to 'trip sit'. A person who remains sober and that can help out if needed.
• Avoid snorting as anecdotal user reports are this is extremely painful and can damage your nose and cause nose bleeds.^{3, 11}

Withdrawal

There is limited information regarding regular use of 2C-B and withdrawal symptoms.
