How long is 2C-B traceable after use?

How long a drug is detectable in your blood or urine depends on a number of factors. How often and how much you use and your personal metabolism (the speed at which a drug is broken down by your liver) are of influence. Drugs are absorbed into the blood and broken down mainly by the liver. Then drugs are excreted through the kidneys in the urine. Drugs are therefore longer detectable in your urine than in your blood.

It is not known how long 2C-B is detectable in blood or urine. It is likely that this is about the same as with MDMA/XTC. MDMA is broken down by your liver. There is nothing detectable in your blood or urine within 2-3 days after use.
