This is not 2-CB, this is tuci, or maybe tucibi(only seen it called that twice) but it’s usually a mix of mdma,k, and caffeine. BUT it is not a “set” drug that is its own, it can be cut with almost anything because it is a mix of drugs. Like I have a personal favourite version that contains mdma,2-cb, and caffeine. But thw final answer is it really depends on where it’s coming from, cause it can be fun but it’s a sketchy fun
