this is the difference . . .

. . . between addicts and everyone else. Addicts understand what this guy is saying, and everyone else just can't:

"CHICAGO, June 14 — The police and health authorities are struggling to track down the source of a doctored, intensely powerful heroin that has killed at least 130 people in and around Chicago and Detroit and sent hundreds more to hospitals in cities from St. Louis to Philadelphia.

. . .

One heroin user, Sean H., 20, who was visiting the treatment van and spoke only on the condition that his last name not be used, said a friend died six weeks ago from a fentanyl-related overdose. The man, 24, specifically sought out fentanyl, Sean said, and had just recovered from one overdose. His body was found on a train.

Sean says he and his brother, who also uses heroin, are more careful now and always have naloxone on hand when they take drugs, though he thinks that none of the heroin they have taken has contained the additive. But the talk about the intensity of the fentanyl experience has intrigued him, he said.

"From an addict's point of view," he said, "that intensity is what you want."
