How do I help getting someone to quit smoking?

I have a friend who is 16 and really wants to quit smoking, and has asked me for help. We’re both under-age, and she doesn’t want her mom to find out. It’d also be nice not to have to use too much money. I really want to help her, but I have never smoked myself, nor been addicted to anything.

I really want tips on how to quit, not how to tell her how to quit. She has quit before, but she falls back into doing it again, but she honestly wish to stop. Please help 🙂

Can someone advise me about how to quit smoking marijuana?

I smoke daily and have always enjoyed it. But I feel guilty for spending so much money and living life with a buzz. It feels like I always need to be high just to get through the day and I never lived this way before I started smoking years ago. All of my friends smoke weed and it would be hard to be around them when they do it. I am also scared I will be terribly bored or won’t know what to do with my time. (learned habit, i know)
How can I go about quitting smoking weed? What are some benefits to quitting? Some encouragement to quit? or some ideas to hang out with friends or stay sober?
