Apparently an animal antibiotic called levamisole is getting added to the coke right in the labs in South America, before it ever makes it up to the USA. It’s almost undetectable - looks like coke, dissolves in bleach, etc. Nobody is sure why the cartels are cutting their coke with it, could be just to stretch it further and sell it as pure coke, could be because it has a potentiating effect that makes the effects of coke stronger. In any case, apparently it has a significant and cumulative chance to cause “Agranulocytosis” which basically makes all your white blood cells die and your immune system goes to shit. Because it’s added by the cartels at the source, this impacts all cocaine - powder, crack, whatever.
I’ve never done cocaine because based on what I’ve read about its effects and my addictive personality, I’ve always assumed that I would become completely addicted to it and ruin my life pretty much right away. But now I’m really, definitely, never doing coke if this shit is true. Pretty crazy!
