They are better in terms of addiction- but in terms of cancer risk it's a wash.

Due to how poorly regulated the liquids are it has the potential to be worse as well.

Sorry what does "it's a wash" mean here?

We have on the one hand a known bad thing, cigarettes contain all sorts of nasties, tars, combustion products etc etc

On the other we have propylene glycol and vegetable glycerin, nicotine and food flavours that get vapourised (not burned). These have no proven links to cancer, PG and VG are already used in food and in medicines, some for inhalation. Also stage-smoke. There's no reason to think they are anywhere near as hazardous as smoking, though we haven't got good long-term data yet.

Regulation of ingredients would be good, but smoking cigarettes and vaping is very far apart in expected health outcomes.

What specific cancer risks are you referring to? The only serious reports I've run across are

which reports increased levels of aldehydes (formaldehyde, for example) from the breakdown of the propylene glycol and glycerin.
