Any thing that goes into your body is either good or bad for you. Such as smoking/vaping are bad for you. Yes vaping is a better alternative then smoking, but long term effects and health risks are not fully studied yet. Yes it could be bad, but we don't know how bad yet.
From what I know nicotine is extremely bad to ingest and or touch with bear hand/skin.

It just means it's unhealthy like smoking cigarettes, and contains ingredients that are bad for you, but not all the crap cigarettes have.
