For heavy smokers who cannot quit smoking immediately, E-cigarettes are the best alternatives for health concerns.
In August 2018, Public Health England published an evidence review. This review concludes that e-cigarettes are significantly less harmful to health than tobacco and have the potential to help smokers quit smoking. The review also states that nearly half the population (44.8%) don’t realize e-cigarettes are much less harmful than smoking.
The comprehensive review finds that about 2.5 million people use e-cigarettes in England, PHE says, and 51 percent, almost 1.3 million, have stopped smoking entirely. Half of vapers who still smoke say they are using e-cigarettes to help them quit smoking or to prevent them from going back to cigarettes. The current best estimate is that e-cigarettes are around 95% less harmful than tobacco.
