This is the '14 times more likely' study -
journals.lww.com/cmj/Abstract/publishahead/Analysis_of_factors_associated_with_disease.99363.aspx
It's tiny - only 78 people, of whom 11 deteriorated.
27.3% of the 11 patients who deteriorated had 'a history of smoking' (so not necessarily current smokers). This is 3 patients.
3% of the 67 patients who improved or stabilised had 'a history of smoking'. This is 2 patients.
So there were 5 patients with 'a history of smoking' in the whole group of 78, or 6.4%. This is incredibly low compared with overall smoking prevalence in China.
I'm pretty disgusted that PHE have released such a strong, scaremongering statement based on one tiny study.
There are now two papers looking at preliminary data from a range of studies, including this one, and it does appear that smoking prevalence among hospitalised patients is consistently lower than among the general population, both in China and the US.

There are of course all sorts of reasons why these findings may not be accurate (NOBODY in public health wants them to be!) and the upshot is that we need to collect better data before we can conclude anything.
We don't have any data on vaping and covid19, however completely switching from smoking to vaping eliminates around 95% of the general risks associated with smoking. This is why the NHS records vapers as non smokers.

The WHO statement is very interesting and is about the most restrained thing they have ever said about smoking!
They say that smokers are more likely to have underlying conditions that are known additional risks for covid19
They say that the hand-to-mouth action of smoking and sharing water pipes increase the risk of infection
They very carefully do not say that smoking per se increases the risk of becoming seriously unwell
Quitting smoking is generally a very good thing to do for your health.
For some people, lockdown is the perfect opportunity to quit. For others, especially those with mental health conditions, the constant state of bored terror and being forcibly cooped up with family make this the most difficult time of all.
If you are quitting using nicotine replacement products or vaping you stand a greater chance of success if you use plenty of nicotine and don't cut down too quickly. You can double up - e.g. use a patch together with a shorter acting source such as gum, spray or vape. If you are vaping then start on a decent strength liquid and use it as often as needed (it's a much more little-and-often thing than smoking).
If you are going cold turkey lots of people find Allen Carr's 'Easy Way ...' book very helpful.
If you can get through to your GP you might be able to get a prescription for Champix but it's not suitable for everyone.
If you are finding it impossible to quit then don't panic, the data so far does not suggest that smoking itself increases your risks of severe covid19 illness. Life will not always be this stressful. There will be easier times to quit.
Pay extra attention to hand hygiene and don't share fag packets, lighters, vapes, water pipes or spliffs.
