What do they use to dye what they sell as fent? purple/blue/green etc is what it was when I last heard.

I've heard all kinds of crazy rumors. Apparently what everyone wanted in my area was blue a few months ago and now it's apparently purple. I've been off it a while but I've always wondered how they dye it. I used to chill at 1 of my big plugs apartments and he'd have a couple of dudes in PPE making the fent dope in another room but it was understood you don't ask any questions about it or go in there. I always wanted to ask him but never did and he's dead now.

So does anyone actually know? Someone told me if it was purple it meant its mixed with iso. I've heard some stuff sold as fent is all iso and no fent. This is all just junkie speculation though. From the addicts I know that are intelligent enough to try to keep up with what may be in their dope. I had a friend ask me what's used to dye the stuff crazy colors and it sparked my memory of how I had that same exact question so long. I figure it's something inactive to work as a trademark like a stamp on a stamp bag and also as a warning saying "this crazy colorful shit sure ain't no h" but how's it done?

If anyone saw that episode of how it's made I'd like to know. Even tho I'm out of the game I still get questions from ppl irl, probably bc I I a reputation for being able to answer them bc I was on here so much. I don't think what they sell here (part of East coast) is even fent. I think it's some RC mixed with tranq. Everyone tells me they don't get high but instead just pass out and always have dry mouth.

We need to crowdfund a mass chromatograph or spectrometer or whatever to test and see what's actually in the drugs. I'll get the ball rolling and donate the first $5 While we're at it we should crowdfund a r/opiates HQ. I'm thinking 1 liked the place the xmen lived in. I want to know what's ruining and killing ppl I know and love. I really think it's obscure opioid RCs, tranq and maybe a tiny bit of some fent analogue. The real mystery is . . . . . .

How do they dye it those funky colors? Makes me LOL to picture them all sitting and using extreme focus to carefully color white rocks blue but that's not it.

TLDR Do you know what they use for dye on the east coasts fetty? If so, then what? And how?

I'd be very thankful for any info given, this question has been sneaking around the holes in my brain like 2 years?

Ty either way. Be careful. And stay safe
