Stop yourself? First time I used heroin since pretty much the start of this year was a few days after finding out about caps death. Same with drinking now that I think of it.
First time I'd used benzos in about 3 and a half years was the day I found out.
First time I'd had a cigarette in just shy of a year was the day I found out.
I don't think most addicts stop cause they've experienced a loss, they use more. Or start again.
Drugs are already very much an act of self medication and self soothing for many. More stress and more pain = more drugs to deal with it.
It's why I've been a lot more worried about everyone else right now, and I've seen others more worried about me.
Though I'd say caps death was more caused by mental illness than drug use, even though drugs were the cause of death.
Good luck man, it's not easy to stop, it's even harder to stay stopped.
