Pharmacology

In common with other psychedelic drugs, 2C-B and other 2C-x drugs bind to the serotonin 2A (5-HT2A) receptor. Serotonin is a neurotransmitter mainly present in the central nervous system that plays a key role in stimulating mood, appetite and sleep regulation. While 2C-B lasts for around 5–7 hours, other 2C drugs vary in their potency (with doses between 6–150 mg) and duration of effects between 3 and 48 hours.

2C-C, 2C-D, 2C-E, 2C-I, and 2C-T-2 show no activity as monoamine releasing agents (like amphetamine and MDMA) nor reuptake inhibitors (like cocaine and antidepressants). Additionally, 2C-B does not impact oxytocin levels, in contrast to MDMA.

2C drugs are metabolised by monoamine oxidase (MAO) enzymes. MAOI drugs such as phenelzine and selegiline block this enzyme, increasing the amount of 2C drug in the bloodstream which can lead to overdose and hospitalisation. Mixing psychedelics with stimulants may increase the risk of a ‘bad trip’ for some people.
