2C-B (4-bromo-2,5-dimethoxyphenylethylamine), also known as nexus, bees, or Venus, is in the phenethylamine family. It is a strong hallucinogen, and its spectrum of effects is diverse. Just a few milligrams can make a big difference. Users report strong changes in perception and intensified physical awareness. Like MDMA (see Infobox 4), it is empathogenic and causes euphoria, but is also an aphrodisiac. High blood pressure, elevated body temperature, nausea, reduced hunger, attacks of sweating, attacks of vertigo, inner turmoil, and cardiac irregularity are also possible. If high doses are taken, loss of orientation, confusion, and feelings of anxiety can lead to horror trips.
2C-B is usually consumed orally and is difficult to detect in the blood because of its short half-life. However, it can be detected for up to three days in urine. Its effects last a total of four to eight hours; the maximum effect is reached after only 1 to 1.5 hours and the effects can continue for two to four hours. Coming down generally takes about one to two hours (also see ).
