Vaping got me off smoking, incredibly easy compared to other methods, so whilst actual cigarettes are on sale then they need to keep the vaping rules relatively relaxed in comparison or increase the rules on cigarettes. There are rules in place which are fairly adequate for vaping, but they're not particularly well enforced.
As for kids, they're banned for anyone under 18, and stopping the under 18's getting their hands on them and using them should be enforced much stronger, but at the end of the day they almost certainly do a hell of a lot less damage than sweets and booze, never mind cigarettes.
The big problem the UK has at the minute for health is obesity (for kids and older folk), it would seem a bit odd to go after vaping without going after sweets, junk food and booze first, which all significantly contribute to this. Cigarettes should have been fully banned at least 5 years ago, since vaping took off etc.
As for people vaping in public places where it's banned, the key thing here is it's banned, it's banned in the boro ground I think, but they largely don't enforce it. I've never vaped in the ground, and neither has anyone I've gone to the match with. Now I think about it, I don't think I've actually seen a massive amount of vaping (compared to the number of expected vapers), apart from the odd person, but they stand out a mile and should be easy to chuck out, so just chuck them out? We just go outside at half-time, like the 99% of others who smoke or vape. Same for in pubs etc, it's rare to find one where you can vape, but even then I still go outside. I don't think anyone would be that bothered if they were banned in all pubs, and all internal places (which offer no segregation) and doorways/ high foot traffic areas etc.
As for making vapes taste foul or like cigarettes, there would be little point in this. Vaping isn't the same hit as smoking, so you sort of need something extra and it really helps get off the cigarettes and I now I absolutely can't stand the smell of cigarette smoke, due to this. To be honest one thing I hate now is having to use the same place to vape as which smokers do.
