Opioids Heroin cut with flour?

[PoppyLlama]

I have done H a couple times before and was fine, but im allergic to gluten (wheat, rye, and barley) and the last time i did it my digestive system just like died and was shitting out water. Im not ever doing it again its not worth it. The diarrhea and stomach pain lasted for like 2-3 weeks! which makes me think there was some other weird bacteria in there.
In any case, how often do you think H is cut with flour? Cuz if its alot then I just cant even do it I guess

I've never seen it cut with flour on the east coast. I would think it would be easy to spot though since the heroin around here is tan/brown and flour is white ...
