Hi!
I started smoking around two years ago for the same reason you mentioned, anxiety. Around four months ago I went cold turkey and haven't smoked since.
The thing about cigarette addiction is, nicotine is not that addictive on itself but the act of smoking is what makes quitting harder. And there are almost no habits that can fully replace the act of smoking.
If you were to quit, I suggest you start analyzing your environment and your mood when you are tempted to smoke and try to eliminate the trigger factors as much as you can (I stopped hanging out with my smoking coworkers). Try to put yourself in environments when you're not allowed to vape (I started going to non smoking cafe's for working. that one helped me a lot.) And lastly find better solutions for the internal causes (if it's anxiety you can meditate or journal etc etc.)
One more thing, If you're worried about your health and wanna quit, quit! Because just thinking about the side effects and not actually quitting is gonna give you the side effects PLUS some placebo in result of you thinking about how harmful it is to your body.
I hope this helps.
Good Luck!
