EDIT: oh god, just realized this thread ain't for weed well then:
I've been smoking cigarettes for say, 3 years and also owned a vape once - After like 2 weeks of using it I just didn't feel like vaping anymore. In my opinion it just ain't comparable to cigarettes - it's something completley different. So I eventually stopped using it and just threw it in my drawers. From that moment on, I've been back to cigarettes. Oh well, that's just how it goes/went - atleast for me.
Note: There might actually be people, that can stop smoking (real cigarettes) when vaping, but this is just not for me.
