2C-B HCl is approximately 10% more potent, but many prefer HBr because it is less painful when insufflated.
I’m told by some that this is the best drug to combine with MDMA.
Can trigger methamphetamine false positives on drug tests (as can many phenethylamines according to Erowid).
This is a highly visual but generally non-spiritual kind of psychedelic experience. It appears relatively non-toxic, non-addictive, and does not seem to build much tolerance.
Personally, I don’t like 2C-B at all, but a lot of people love it — especially for parties and sex.
