Depends on character traits of anon.
Some invest/gamble
Some hoard wealth
Some uses it fight boredom like going to places, travelling, hobbies, etc.
Some try sharing with others or straight up doing charities
If all of my money had gone into a charity it would have been, “Junkies Helping Junkies Not Get Dope Sick No More”. :p
Here at junkies, we split shots. We don’t get high. You found some dope on a gas station floor? Three people won’t get sick today. Or, Brenda will convince you that her tolerance is insane because of a recent stay at the hospital, she’ll get half and we’ll split half. She’ll nod out and she won’t be welcome at Junkies Helping Junkies Not Get Dope Sick No More no more.
For real though, been sober for at least a decade at this point. It is crazy how much money people burn through with that little hobby. I don’t miss that life and I’m thankful to be away from it, so if I did accidentally become wealthy I’d give some back to the community that helped me get here. I’d drop by some local AA and NA groups and drop a pile of money under the 1s pretty often.
