These days the dealers cut the cocaine with fentanyl. It’s a lot cheaper, the high is better, and it is more addictive... main problem is that the dealers murder their customers. Not a great business plan.
I was listening to some cop that said the problem with Fentanyl now-a-days is “quality control”. Seriously! He said the demand is so high now that they don’t take the time to crush it up well enough or to mix it well enough with the other drugs.
They’ll find bags of cocaine or pills and when they test them the levels of fentanyl are all over the place. Even pill to pill. One pill might have a trace of it, and the other pill has 10x the deadly level.
