It’s unfortunately true in lots of cases. I(ex dealer and addict 3.5 years clean) never sold anything with fent in in knowingly and we had test kits for our shit. However when another dealer would have someone OD they would have all of the “hardcore” users lined up because their tolerance was so high they needed a stronger fix.

I know a guy who did some heroine so strong that he left his leg tied off and it had to be amputated. After that the dealer had a huge bump in customers. Some will a meth dealer we knew that killed someone by “accident”. The following weeks he had the biggest fiends in the area at his den.
