>Use of the devices is slumping because they are not as good as cigarettes at giving a hit of nicotine

This is total nonsense. You can use e-juice at a level that will give you nicotine poisoning.

I find that I sometimes still crave a cigarette. I suspect that has more to do one or more of the 599 additives (4000 when burnt)[1] in them being addictive.

IIUC, cigarettes have been chemically modified to increase the rate of the nicotine hit, to get nicotine through the bloodstream to where it does its nicotiney job. That's one of the reasons cigarettes are more addictive: the sudden hit followed by a quick drop off.
