Electric Cigarettes on Pesach

Question:

Can one smoke electric cigarettes on Pesach?

Answer:

The liquids used in producing the flavor for electric cigarettes will need to be approved free of chametz.

From a vary basic scan, it appears that some of the liquids use an alcohol base, and this can be a problem of chametz. They also include flavorings, and in short, the cigarettes cannot be used unless the liquid is verified as chametz free.
