I don't know if it did hit the US bad but on the western coast, here, the new deadly trend is call Fentanyl; it's a kind of synthetic opioïd 50 times more powerful than heroïn and 100 times stronger than morphin. The cases of overdose have skyrocketed and the authorities are trying to figure out how to stop the plague. Apparently that most of it is marketed in China and is pretty easy to get shipped oversea without suspicions at all.
