Vaping is sort of in limbo right now between the hardcore adherents and the nay-sayers. The big thing that the tobacco lobbyists scream about is that there haven't been enough long-term studies on the effects of using the vaping liquid.
Right ... like we should feel safer smoking cigarettes because they've "done studies".
You can still get your nicotine fix with some vape liquids, but with far less tar and the other chemicals they put into tobacco. Unfortunately you're probably going to be inhaling glycols and other nasties.
You pays your money and takes your choice.
