I got tired of breathing like shit. I quit using a vape. I found that vape was more addictive, however, easier to quit. I could vape inside unlike cigarettes.

One thing that helps is getting fruit, for me it was apples. I would eat one when I was jonesing. It may take a few times to fully quit, so be aware of that and don't beat yourself up if you slip. Exercise helps too, it releases endorphins and is a great distraction.
