Look no one is saying inhaling eliquid is SAFE, especially flavored. So I don't know that "one" is safer than the other.
What I do know is that no nic will reduce your risk of NICOTINE issues, so if you can do that, probably DO that. However, if you have no need of nic, and you are inhaling purely for fun and flavor alone..... I'm not sure I would BEGIN that habit. It's expensive over the long term we absolutely do not know what will happen, although short term is looking good.
If I could go back in time an NOT start smoking, and be a never smoker and never vaper I 100% WOULD.
If I could never KNOW how wonderful nurturing an addiction that you could (at least in the past) satisfy on my every whim, I would GLADLY give up that knowledge.
I could not have quit smoking without vaping. I am PRETTY sure it has extended my life by a GREAT deal.
However, I don't think I would have picked up vaping for no reason. I'd probably still be participating in bike races, probably MARRIED to a non smoker, and etc.
SMOKING changes your life (IMHO) in EVERY way. I wish I could go back.
I would imagine, for some, vaping may do the same thing. Harm reduction does NOT mean harm elimination and anyone who says it does (at this point in vaping's evolution) IS LYING.
So, chose your options, and choose them CAREFULLY.
Because, you do have the option to ABSTAIN and I can tell you that of ALL the mistakes I've made in this life, the ONE I wish I could do over would be picking up that FIRST cigarette.
Good luck, choose your own adventure but know the risks.
