Purplefowler Thanks for the replies and I'm glad you're not taking my words personally, or as an attack... as that's not my intent, at all. Nice one.
All licenses are prohibitive, in that (say) without one, you can't sell the relevant product. As your tale of buying booze while underage indicates... even the +18 restriction is pretty pointless. I'm sure I'm not alone in beginning my pub career a few years underage, either. I was also sent out to get booze and fags... and I was under 10 at the time and bought them from a village off-licence... which was licensed. For some reason, the same shopkeeper wouldn't sell me matches unless I could spell 'matches.' God alone knows where that requirement or concept came from
I don't think dodgy dealers have any impact one way or the other, to be honest... beyond caricature and prejudice. As you said, there are good ones and bad ones. There are also good 'reputable' vendors and bad ones. The reputations of products sold, e-cigs or whatever, are not harmed in any meaningful way by the people that sell them, unless there is some form of prejudice involved, I guess... towards the product or the seller.
I personally like to buy my PC components from people that know what they're talking about and can answer any question I might ask. I don't usually buy PC components from market stalls OR from PC World unless it's irrelevant and they're significantly cheaper.
With e-cigs, for me in my current vaping position, it has become irrelevant because I do my own legwork and I'll buy from anyone if the quality and price is right, even those that the Daily Mail and Deborah Arnott sneer at, like the Chinese. For those that are clueless about e-cigs, it is obviously better for them to initially buy from people that can advise and answer questions... absolutely... but in my experience, as with PC World, just because a shop is reputable, well-established and full of quality stock doesn't guarantee good advice and product knowledge... or even a faultless and 100% safe product.
In the example you gave, it was a bit of a trick question to ask what the nicotine content of a product that contained no nicotine was, especially as you already knew it to be zero. What was the purpose of the question but to highlight his possible ignorance? If the dodgy one has said 'zero' he may have foiled you temporarily, but your opinion of him would not have been meaningfully altered, don't you think?
As far as the Daily Mail is concerned... either educate, or fight against Daily Mail mentality (which is prejudice with an agenda, to me), rather than act as though it has any legitimacy, surely? Pre-empting them and doing what they would want just to 'dis-arm' them in some way simply reinforces prejudiced perceptions, doesn't it?
I tend to think that it's MY responsibility to know what I'm buying, and MY responsibility to not fall for any bullshit from any retailer, whether in a car-showroom or market, with the caveat that if the product sold is faulty or dangerous, there are already mechanisms in place to deal with that, before and after the sale.
With regards to e-cigs... there is no evidence for restriction whatsoever. In my opinion, of course, though I think I can back it up with evidence.
I'm not sure what you mean by 'token effort to legitimise vaping.' It is already legitimate, in every way, isn't it? Any form of control, basic or no, is a restriction. I am not against ALL restrictions, regulations or laws... but there does have to be, as I said, an evidence-based reason or cause. This, to me, means that IF you argue for control, you have to have evidence that it is necessary and required... AND that it will be effective and has no unintended consequence. It can't be based on prejudice, ideology, misunderstanding or even some rather airy notion that 'it would be for the best.'
As for 'basic standard' - I would agree, in terms of manufacture... but not in terms of sales (as in a license to sell, say). If the former is adopted, then there is no need for the latter.
And you're absolutely right... different perspectives are the juice of life
