Sajid Javid's announcement that the Department of Health is paving the way for e-cigarettes to be prescribed on the NHS in England is deeply worrying.
Yes, there are still 6.1million smokers in England, and while smoking remains the leading cause of preventable death we must redouble our efforts to tackle this problem.
But as a scientist who has spent 30 years in public health research, particularly in regard to heart disease, smoking and diet, I can assure the Health Secretary that e-cigarettes are not the answer.
Worse, they will generate a raft of other health problems.
When vaping first took off seven years ago, I was open to the idea that it might help reduce smoking.
They took off earlier than 2014, although that was when alleged experts like Capewell and McKee finally started paying attention to one of the biggest public health innovations of the century. Anybody who remembers their interventions at the time will find it very hard to believe that Capewell was open to any ideas other than banning them.
But with mounting evidence of the harms vaping can cause, I have become increasingly worried by the unquestioning enthusiasm on the part of some public health bodies whose first duty is to protect us.
Following a 2016 report by the World Health Organisation about the health risks e-cigarettes pose, countries including China and India banned or severely restricted their sale.
England is out on a dangerous limb. Officials here have fallen for the exaggerated claims of the pro-vaping lobby, and are ignoring the health risks. The main claim, that e-cigarettes are a major aid to quitting, is wrong.
If that were true, why would the multi-national tobacco corporations be pushing vaping so hard?
'E-cigs' are a means of attracting new cigarette smokers, as I will explain.
E-cigarettes are in fact one of the least effective quitting tools, accounting for only about 10 per cent of long-term quitters in the UK.
Most people who quit did so before e-cigarettes were on the market. It's not complicated.
Many of those who try to quit smoking via vaping continue to use both e-cigarettes and lit cigarettes. This is a big win-win for tobacco firms. Most of the UK's 3million vapers who still smoke have no plans to quit.
Next let's address the industry claim that e-cigarettes are 95 per cent less harmful than lit cigarettes, a figure based on no solid evidence whatsoever as far as I am aware. Yet this spurious figure was picked up by PHE.
More robust evidence estimates that, at best, e-cigarettes are 50 per cent less harmful.
Champions of e-cigarettes say there is 'no evidence' of long-term harm. In fact, there is plenty of evidence.
Nicotine is highly addictive while the superheating of the 100-plus flavourings used in e-cigs to disguise the taste of nicotine and produce vapour can generate harmful chemicals, many of which are found in lit-cigarette smoke.
Research shows that e-cigarettes can be even more addictive than lit cigarettes which is why the use of youth-focused flavourings such as bubblegum is so appalling.
Nicotine poses a particular risk for the young because it disrupts the development of crucial brain connections.
Personally I doubt very much that e-cig manufacturers will be submitting their products any time soon for UK medical approval.
