Appreciate that bricktop but that info is still incorrect. As someone who has been addicted to fentanyl a few years back, this is not medicinal fentanyl. These are fentanyl analogues that basically have complete different chemical makeups and therefore react much differently than pharm fentanyl. For people wondering why, the explanation above is pretty spot on. Government shut down Prescription on opioids around 2010, added corn starch to oxy and other pain pills to make them tamper proof. Many people, myself included, had nowhere else to turn other than heroin. Eventually people started mixing fentanyl into Heroin to make it stronger and cheaper. Each batch is different, there are 10+ different analogues, so much can go wrong. I shouldn’t be here, so many others should. It’s terrible. And yes, the rehab business is from top to bottom a joke and has a long ways to go compared to the rest of the health world. Another person dead from this addiction, Rest In Peace, life with addiction is tough as is.
