That's how I quit cigarettes - got 0% liquids in a few flavours, hard-quit the smokes and puffed like crazy on a vape to assuage the habit. After around 3 months I noticed I'd stopped caring about the vapes so much and just put them down.

Worked well for me, might not work so well for others.

Personally I thought that was the whole deal with vapes, use them as a tool to beat the addiction to 'real' tobacco products, but it looks like the world proved me wrong on that one.
