My friend got another friend of mine addicted to cigarettes, but he can't afford to buy a pack whenever he's craving one, he has to ask other friends for them. I hate the fact that he's addicted and I want to help.
Let me start by saying I hate cigarettes, or smoke of any kind, and I'm very against it. Now with that being said, it doesn't give me a right to control my friends or tell them what to do. I have several friends who smoke (I ask that they don't do it around me) and to be honest its none of my business what they do with their own body. Same goes for you. You really can't just tell people, especially your friends, how to live their life. It's not your place or your choice to make.
