Fair enough, I'm sure it's not healthy to chronically inhale anything other than air
> If you're asking about drugs with similar effects to nicotine that are less addictive, I'm not aware of any. You could always purchase vaping liquid that doesn't contain any nicotine though.
I was asking that but a broader question for me is, are there any safe replacements for cigarettes out there that match the qualities that cigarettes have without the harmful side effects (the idea being if you could create something that was just as fulfilling, addictive, etc. but without the negative side effects you could dramatically decrease the health toll of cigarette smoking). You could argue vapes are that product but it seems like the jury is still out on how much better they actually are than cigarettes and the trouble with attracting new users into the market
