They allow a smoker more control and flexibility over any smoking alternative currently on the market by giving the them the ability to choose their own nicotine level and flavor. A smoker can choose from high, medium, low, or even non-nicotine and also choose units that allow for custom vapor production tailored to suit their specific needs.
Are e-cigarettes safe?
While anything containing nicotine cannot be called 100% safe, evidence from numerous studies strongly suggests that they are magnitudes safer than tobacco cigarettes. Harm reduction experts can point to research supporting that switching from cigarettes to a smokefree product will reduce health risks to less than 1% of smoking traditional cigarettes - nearly the same as non-smokers. For tobacco harm reduction health professionals, it is misleading and irresponsible for public health officials to tell smokers that smokeless products, such as e-cigarettes, are "not a safe alternative to smoking" simply because they are "only" 99% safer and not 100% safe.
