i would argue that the evidence available on here and other websites appears to show a far higher percentage of people succeed with an ecig than would ever have done with the other products currently available on the NHS, the incident they keep referring to was in an american test in 2009, a contaminate was found at a minuscule level in one cartridge they tested but was never found again, it could have even been a miss test or from cross contamination, hangsen eliquid conforms to all current UK requirements, Also the cartridge type is nowhere near as popular as the vap type most of us now use,
