“E-cigarettes either do not contain or have lower levels of several tobacco-derived harmful and potentially harmful constituents compared with cigarettes and smokeless tobacco… [e-cigarettes] present an opportunity for harm reduction if smokers use them as substitutes for cigarettes.” The current best estimate is that e-cigarettes are around 95% less harmful than smoking"Nearly half the population (44.8%) don’t realise e-cigarettes are much less harmful than smoking E-cigarettes are not completely risk free but when compared to smoking, evidence shows they carry just a fraction of the harm. The problem is people increasingly think they are at least as harmful and this may be keeping millions of smokers from quitting. Local stop smoking services should look to support e-cigarette users in their journey to quitting completely. Smokers who switch to vaping remove almost all the risks smoking poses to their health. Smokers differ in their needs and I would advise them not to give up on e-cigarettes if they do not like the first one they try. It may take some experimentation with different products and e-liquids to find the right one.
