title_body: Vaping Alcohol - fad or here to stay?
upvoted_answer: Limit: So, I would speculate that if you're "vaping" the same quantity of alcohol as you might instead drink, then you're facing the same risk. It's the same as drinking alcohol - the risk is cumulative and hard to define - it really depends on how much you drink and how often. 
  
  Effect on lungs: Frankly this is hard to say, as I am quite confident there have been no large scale (AKA reputable) studies (nor can I find any) performed on the effect of vaping alcohol on lung tissues. I would expect the effects to be minimal, but then again, personally, I'd probably still just stick to drinking my alcohol.
  
  I can't provide any scientific basis to this, but I am thoroughly confident that vaping is simply a fad or novelty to enjoy - think of the increased costs and lack of accessibility compared to just drinking alcohol - you simply need a bottle of beer and a fridge, or a bottle of spirits and a glass versus a specialised glass, tea candle, vapour catching vessel and a glass or metal straw (seriously, who keeps one of them around?).
