2CB is a synthetic, psychedelic, recreational drug that is fairly common in the club scene and beyond. Although many people who indulge in psychedelics may take 2CB on a regular basis, it can also be dangerous due to the sometimes frightening hallucinations that it may cause. Anyone who uses 2CB should know what could potentially happen if they take too much, and anyone who uses it on a frequent basis may wish to seek treatment to stop. Read on to learn more about it.

What Is 2CB?

2CB was first synthesized by American medical chemist Alexander Shulgin in 1974. It is known by a number of street names, including the 2CB slang tuci, tussi, or tucibi.  Originally intended for both stimulant and psychedelic use to aid the psychiatric community during therapy, it’s still used for those purposes today by those who use it. Is 2CB legal? There are no true, approved medical applications today – it is illegal – but its use is fairly widespread in both the United States and Europe.

When MDMA was made illegal in 1985, 2CB became popular in the United States as a potential substitute for young adults attending early raves. It’s still popular in the club scene and is sometimes still sold as ecstasy, even though its effects are rather different.

What Is 2CB Used For?

This drug is purely made for recreational use these days, but for a time, it was sold as an aphrodisiac under the name Erox by a German pharmaceutical company, and it was also sold in the Netherlands under the names Nexus and B-Dub.

Today, people who use 2CB use it to experience hallucinations and also as a stimulant. This drug is popular in rave and club culture because it helps users to stay awake and dance for hours. It also is a mild entactogen; users report feeling connected to others when they take it.

2CB Dosage

There have been few studies on 2CB over the years, so there is little data about safe dosages. The common oral recreational dose is between 15-25 mg. Severe reactions are rate, but if someone takes too much of it, they may experience frightening hallucinations. When taken orally, 2CB lasts about four to eight hours; when it is insufflated, the duration is usually around two to four hours.

No lethal dosage is known. When 2CB is sold as ecstasy, there is usually only 5mg of the drug mixed in with other ingredients, which is why it can often pass as this very different substance.

Effects of 2CB

Many users of 2CB report that it is more easily managed than other psychedelic drugs despite its high potential for intense hallucinations. At low doses, 2CB effects can be controlled rather easily, and at any dosage, the hallucinations tend to come and go in varying waves of intensity. Many users report difficulty concentrating, giggling and laughter, auditory hallucinations, and visual acuity. Conversation may be challenging; coordination may be difficult as well.

Potential for 2CB Addiction and Abuse

2CB is considered to be non-addictive, but some people who use it a lot may find that they are using it more and more over time. If this is the case, they may wish to seek support to stop. 2CB tolerance is unusual but could happen with frequent use.

One major issue with 2CB is the fact that it is sold as a powder, and that powder is often impure. It’s hard to know what drugs are in any sample of something sold as 2CB. As fentanyl and heroin appear in more and more drug samples today, it’s possible that a 2CB user may end up ingesting something far more dangerous than 2CB.

Warning Signs of Abuse

If someone is under the influence of 2CB on a regular basis, they are probably using it too much. This drug is not addictive, but like all psychedelics, it’s wise to use it only in moderation.

2CB Risks and Dangers

There are some common 2CB side effects of which users should be aware. Some users report feeling jittery and mild muscle spasms. Others report shuddering breath, which may or may not be a pleasant feeling, depending on the person. Further, mild to intense general gastrointestinal discomfort is common.

Again, at high doses – those from 30-40mg or higher – users may experience some terrifying hallucinations. If the user is not in a safe place, these types of hallucinations could be life-threatening under certain circumstances. The amount of the drug needed for 2CB overdose is unknown.
