Oh that's interesting. I thought they were referring to
https://en.wikipedia.org/wiki/2C-B
a drug I experimented with once. suffice it to say I ended up in a hospital emergency room without a shirt, demanding that they x-ray my leg because I thought there were worms crawling inside of it. Never doing that **** again.
when actually, from the wiki article.
A powder which has been dyed pink may be sold as "tucibi", "tussi" or "pink cocaine". This is not synonymous with 2C-B and instead refers to a mixture of drugs with pink dye.[9] It is very rare for tusi to contain 2C-B, with the most common ingredients being ketamine, MDMA, and caffeine.[10]
So the CB in the article is actually this "Tucibi" mixture, as noted in the title of the article.
