Experts say new steps China has agreed to will eventually reduce the flow of the deadly opioid fentanyl into the U.S., but that alone will not stem the overdose crisis killing Americans at a record rate. Synthetic opioids are now the biggest killers in the deadliest drug crisis the U.S. has ever seen. More than two-thirds of those deaths — more than 200 per day — involved fentanyl or similar synthetic drugs. It's in counterfeit pills and cocaine, in some cases causing overdoses in people who have no idea that they're using fentanyl. A growing number of places are allowing drug screening kits so users can find out if their drugs include fentanyl.
