It depends on your relationship with this kind of person. If it were a random guy I met in a casino, I wouldn’t even counsel or give him advice, as I don’t know his temper or character; it’s his own business.

If he is someone close to me and he trusts me, then I will try to give him the best advice that I can provide so he can ease up on his addiction. A person needs to trust you first before they will listen to your advice; you can only advise someone who trusts you or asks you for advice.
