Leo Beletsky, a drug policy researcher at Northeastern University in Boston, said that evolution is a predictable outcome of the “iron law of prohibition,” which holds that any banned substance will become more concentrated to maximize its financial return.
“It takes a lot of effort to produce heroin,” he said. “It takes much less effort to synthesize fentanyl in a lab, so I imagine the market will continue to turn in that direction. … I think we’ve not seen the peak of the overdose crisis.”
