I am a former addict. I relapsed after being clean for a very long time and I am shocked by the quality of drugs, as well as the cost

I am sure this is not a new issue that I am talking about. I am not sure what other drugs do but am primarily a heroin addict. I was addicted for a long time in the past. Just a couple days ago I had a very serious relapse. I am horrified at the price of heroin and then I found out that almost every heroin dealer is mixing it with fentenyl. I am terrified that I am going to get some heroin mixed with fentenyl and die. The heroin is also very weak and doesn't last very long at all. I am not trying to make excuses as I know I am to blame for relapsing. I don't remember heroin being so expensive and it never used to make me itch or give me heartburn. I am also extremely angry about the fact that heroin dealers are mixing heroin with fentenyl, it seems like they want to kill you. I am going to get help as soon as possible.
