I smoked for over 25 years and generally I wasn't concerned, I've now been cig free for nearly 2 years, I started vaping because I was getting more worried about smoking, I think as we get older we start to become more aware of the things we do that can have a negative impact on our health.
As far as the Atlantis tank goes, I was just sharing information, what someone does with that information is none of my business. I don't use clearomisers anymore so it doesn't affect me but felt those that do and are unaware of the chrome plated brass (not naval brass) on the chimney and the ceramic wicking material had a right to know, they can then make an informed decision whether to continue to use those products, much like the diketones in Nicoticket juice, we know it's there and can act accordingly, I choose to continue using Nicoticket, others may feel differently.
