my dad vapes

what do I do?? my dad vapes, for years he's been swapping out addictions, before I was born he was a heavy drinker and smoker. I remember him being a smoker when i was younger and he used vaping to quit, except he never stopped he's getting worse, he's always going to get vape juices and everytime I see him he's got it in his mouth or just holding it so it's there.

if he doesn't stop im scared of losing him but I don't think he'll quit
