This is kinda off topic but I recently started lock picking. It’s fun and challenging, and it gives me something to fidget with. I feel like it’s less challenging than a Rubik’s cube, plus it can be useful if you lose a key. Lots of good how to videos on YouTube as well.
As long as you aren’t harming others I personally don’t see a problem with weed or THC products. We use drugs to numb our pain, I don’t see how numbing our minds to emotional pain is any different or worse.
