I agree with this. There is going to be more regulation on ecigs. That much is inevitable. I think it should look something like this.
EShisha should be banned. (or at least treated the same as ecigs) It's a work around to sell on ebay. They are ecigs and should be classed as such.
All ecig liquid and prefilled cartos etc should have to meet minimum standards for quality and there should be some kind of license that you need to get to be able to produce e-liquid. Same kind of standards of quality that you need to produce food which would put such a license easily within reach of a small business. Provided that you work in a clean environment, use clean bottles, adhere to CHIP regs and get samples of your liquid GC-MS tested every 3-6 months or so for nicotine strength and absence of nasties then you're good to go. Assuming that it cost a few hundred quid then it would put a delay for new e-liquid manufacturers of a couple of months (waiting for first lab results) and lots of small 'artisan' people would be able to make the stuff in a kitchen without needing to invest in clean rooms, high tech equipment and such a license would mean that insurance companies would offer PLI for e-liquid manufacture (which is pretty much essential if you make e-liquid, and is presently far out of reach of small to medium businesses) to licenced producers at a reasonable rate.
Any e-cig related sales must only to be to 18+ adults only - same age restrictions as for cigarettes.
They should keep e-cigs as consumer products but tidy up the other regulations a little to make it easier to enforce and easier to follow. Things like the sale of goods act can be a bit ambiguous (how long must a guarantee on an eGo bettery be? - what about atomisers is a DOA warranty legal for the whole atomiser or just the coil head?) there's a bunch of similar loose ends that could be tidied up.
The less control Big T or Big P can exert over the market the better and I think a license setup like that would encourage lots more competition among small businesses and stop the really bad quality cowboys selling on facebook and markets and the like.
