Juul doesn't really create enough vapor to have a distinct flavor. If you do sub-ohm or use better quality devices that create more vapor you get amazing flavor as well. This can very well approximate the flavors of most candy and dessert products, along with satisfying that hand to mouth urge (Freud would say I have an oral fixation).
I switched from traditional fags to e-cigs a decade ago and there are quite a few diabetics on the ecig forums who use ecigs, instead of for nic replacement as a sugary dessert replacement with success.
