Long-term vaping 'far safer than smoking' says 'landmark' study Read the full story here

Dr Yadav's opinion and summary below:

VAPING is the use of electronic cigarettes or e-cigarettes. These devices (VAPE) are held in the hand & work by heating a liquid to generate a vapor and simulate the feeling of smoking. The liquid is called “e-liquid” or =e-juice” and may or may not contain nicotine. It usually contains glycerine and flavoring with nicotine and propylene glycol. Vaping has become more common in the last few years, mainly due to the digital marketing efforts of companies selling the vapes.

Since this is a new trend we do not know the long term benefits and harmful effects of vaping. However, there are some differences between smoking and vaping that are clear:


  1. E-cigarettes usually do contain nicotine just like cigarettes - although individuals may be able to prepare their own nicotine free flavored e-liquid with some effort. The amount of nicotine released (vape vs smoke) is about the same. (Mayo Clinic)

  2. Hand held use of a nicotine source, potential for addiction, graduation to smoking.


  1. E-cigarettes limit exposure to the harmful substances (which are toxins and cancer inducing substances or carcinogens) which are generated by tobacco smoking, such as tar and carbon monoxide, because they are heating liquid to make vapor,

BOTTOMLINE: Should you start if you don’t smoke or vape? NO. Should you switch to vaping if you smoke? YES. Should you use vaping as an aid to quit smoking? YES. Is it fine if you keep vaping and cut down smoking? NO. You’re still at risk. Quitting smoking AND vaping is ideal.


The effect of nicotine on the skin is not completely understood, and remains controversial. (See but vaping may be better for skin than smoking, at least. However, it is true that nicotine is an addictive compound and most likely, combined with the other toxins that are present in e-cigarettes, will cause premature ageing.

Thus the answer to the question: Are e-cigarettes bad for your skin, is a very likely YES.



The National Health Service in the UK makes the following observations on their website:

“ The study was carried out by researchers from a number of institutions, including University College London, and the Roswell Park Cancer Institute and Centers for Disease Control and Prevention (both in the US). Funding was provided by Cancer Research UK. The study was published in the peer-reviewed journal: Annals of Internal Medicine.

The study, involving 181 smokers or ex-smokers, has been described as "landmark" as it is thought to be the first (or at least one of the first) looking at long-term vaping outcomes in "real world" users. Previous studies of this kind have mainly relied on laboratory equipment, or animal research, to estimate the long-term effects of e-cigarettes.

The volunteers completed questionnaires and provided breath, saliva and urine samples. The researchers found significantly lower levels of toxic chemicals and cancer-causing substances (carcinogens) in the samples of those of former smokers who had been using e-cigarettes or nicotine replacement therapy (NRT) compared to current smokers.

Another noted result is that current smokers who may be trying to reduce their risk of harm by switching between e-cigarettes and normal cigarettes may be saving money, but doing little for their health. "Combination users" still had very high levels of toxins and carcinogens

This study provides evidence that e-cigarettes and NRT can reduce harm to smokers by reducing exposure to toxic chemicals. The evidence would also seem to support Public Health England’s 2015 report that “E-cigarettes are 95% less harmful than tobacco”.

The findings of this study do appear to reassure that use of e-cigarettes and nicotine replacement therapy – while continuing to provide nicotine – can reduce exposure to toxic chemicals that can lead to cancer in cigarette smokers. However, this is only if you completely stop smoking – using e-cigarettes or NRT while continuing to smoke won’t help. Smokers who want to stop smoking can get help from NHS stop smoking services, which can reduce their risk of smoking-related disease and death.”

“Reasons for using e-cigarettes involve trying to quit smoking, reduce risk, or save money, though some use them recreationally.[16] As of 2014, the majority of users still smoke tobacco.[23] There are concerns that dual use of tobacco products and e-cigarettes may "delay or deter quitting".[23] About 60% of UK users are smokers and roughly 40% are ex-smokers.[34] In the UK use among never-smokers was negligible.[34] Because of overlap with tobacco laws and medical drug policies, e-cigarette legislation is debated in many countries.[35] A European directive of 2016 set standards for liquids, vaporizers, ingredients and child-proof liquid containers.[36] As of August 2016, the US FDA extended its regulatory power to include e-cigarettes.[37] There are around 500 brands of e-cigarettes, with global sales in excess of US$7 billion.[38] “ - Wikipedia
