Former heroin addict here.

The one thing we all have in common is that we are in some kind of pain that we are trying to escape—it is a painkiller after all. What people don’t know when they start is that it also kills all feelings of remorse or decency because you can’t feel the pain of embarrassment or social expectations. It is a sneaky high that doesn’t hook you at first, and the moment you wake up sick, you’re already on the wagon.

I’m sorry your friend wound up doing that, and I’m sorry for how it affected you. I hope you get to the point where you can integrate the awareness that addicts of hard drugs are victims of a chemical that is changing their entire perception of reality sometimes, and they often don’t understand what is really going on until the consequences become severe. I hope your friend gets the help they need to see what is happening to them and how to stop the damage.
