I guess in the politically correct EU state that we live in, removal of that e petition would be a violation of free speech.
I have run a business since 2009 selling electronic cigarettes. In recent months I've seen a sharp increase in the number of pensioners buying them. I've spoken to many of them personally and the number one reason for most of them doing so is that they have a health problem (heart or hip/knee replacement being the most common) and the doctors/hospitals are refusing to treat them unless they pack in smoking. Most of them have smoked all their lives and find it nigh on impossible to quit, but find the electronic cigarette easy to switch to as it mimics the smoking action, but without any tobacco.
Personally I think it kinder to let them smoke these devices and allow them to have their health treatments than have them denied treatment altogether. Let's not forget that the vast majority of them have worked all their lives and therefore contributed both tax and national insurance into the system.
