As the worst addiction crisis in American history has shifted from prescription painkillers to heroin and now to illegal synthetic opioids like fentanyl, the death toll and drug dealers' profits have risen together.

Some perspective from a Bloomberg dive into the fentanyl supply chain: A pair of undercover detectives were able to buy a kilogram of fentanyl from China for $3,800. Once turned into tablet form and resold on the street, that’s enough to yield more than $30 million in profit.

  • A kilo of heroin, by contrast, would turn a mere 400% profit — and it’s a lot harder to get.

Fentanyl is incredibly potent. So a little bit of raw supply can go a long way. And it’s synthesized unpredictably, making it hard to know how much you’re taking (and thus more likely to overdose).

  • It’s also easy to synthesize, and China only recently outlawed some forms of fentanyl. For years, manufacturers have been shipping illicit compounds across the globe, including into the U.S., without violating Chinese law, Bloomberg writes.

“The two countries play by different rules,” Markos Kounalakis, a visiting fellow at Stanford University, told Bloomberg. “What’s bad for America is not necessarily bad for China.”

The silver linings of online school

Online learning can be frustrating for students, teachers and parents, but some methods are working.

The big picture: Just as companies are using this era of telework to try new things, some principals, teachers and education startups are treating remote learning as a period of experimentation, too.

Sen. Elizabeth Warren and Hillary Clinton both are slated to speak on the Wednesday of the Democratic convention — Aug. 19 — four sources familiar with the planning told Axios.

Why it matters: That's the same night Joe Biden's running mate (to be revealed next week) will address the nation. Clinton and Warren represent two of the most influential wise-women of Democratic politics with the potential to turn out millions of establishment and progressive voters in November.
