Hi, I recently had a heart attack (I'm only 41) and decided to quit smoking. I bought a couple of 510's from http://www.electroniccigarette.uk.com/ and after a month I haven't gone back to the dreaded tree. I was thinking about ordering a better ecig to give more vapor and have better battery life as I'm really not getting as much out of the 510 as I should be, im using a 26mg tobabbo juice and was worried about the amount of nicotine I'm taking in and if it will affect my heart condition at all? as I'm in the UK would ordering off Vaportalk incur any taxes for me? do the charging kits come with a UK/EU plug or adaptor? I love vaping and have become addicted to it! but I'm thinking it's gotta be better for me than smoking is. I just want to make sure I'm not damaging my heart anymore than it is?
