Yes I’m interested in a learner or learner/earner.
Look if he is working on himself than that’s another story, but only if he has the goal of stopping and it actually trying to get there and seeing people, going to meetings and stuff to stop his addiction.
You may think “Oh, it’s just smoking” but in reality it’s an addiction, an escapism that needs help. I’d look at it in the same way as someone with a smartphone.
