Is vaping better than smoking?
And can your lungs heal from the effects of e-cigarettes?
MANY people have decided to swap smoking cigarettes for vaping instead.
The purpose of e-cigarettes is to help smokers quit, but are they a healthier alternative? Here's what you need to know...
Why is vaping better than smoking?
E-cigarettes contain nicotine but not many of the harmful substances produced by smoking tobacco, such as tar or carbon monoxide.
However, there has been debate about exactly how safe their use is.
In the UK, e-cigarettes are tightly regulated for safety and quality.
They're not completely risk free, but they carry a small fraction of the risk of cigarettes.
E-cigarettes do not produce tar or carbon monoxide, two of the most harmful elements in tobacco smoke.
The liquid and vapour contain some potentially harmful chemicals also found in cigarette smoke, but at much lower levels.
While nicotine is the addictive substance in cigarettes, it's relatively harmless.
Almost all of the harm from smoking comes from the thousands of other chemicals in tobacco smoke, many of which are toxic.
Nicotine replacement therapy has been widely used for many years to help people stop smoking and is a safe treatment.
There's no evidence so far that vaping causes harm to other people around you.
This is in contrast to second-hand smoke from smoking, which is known to be very harmful to health.
What is vaping and what are e-cigarettes?
Vaping is the process of smoking e-cigarettes, allowing a person to inhale nicotine without other harmful substances in tobacco.
The term is used as e-cigarettes do not produce smoke - instead releasing a vapour.
The vapour is produced from a material such as an e-liquid.
Millions of Brits now get their nicotine hit via e-cigarettes, and they are continuing to grow in popularity.
E-cigarette is another name for electronic cigarette.
It is a handheld device that gives you the same feeling as smoking a normal tobacco cigarette.
The first modern e-cigs were developed by Chinese pharmacist Hon Lik who wanted to create a safer alternative to smoking.
E-liquid is the mixture used in vapour products.
In May 2018, top doctors called for flavoured e-cigs, such as strawberry, bubblegum and chocolate to be banned as they said they encouraged kids to try the devices.
And they said the evidence does not support the concern that e-cigarettes are a route into smoking among young people.
They claim e-cigs are 95 per cent safer than traditional cigarettes.
And they suggest smokers should consider switching to vaping in a bid to help them quit.
However, in 2019, there was an outbreak of severe lung illness among e-cigarette users almost exclusively in the US.
Initially, doctors were baffled by the surge in similar lung diseases before they were eventually linked to vape usage.
The US Centers for Disease Control and Prevention (CDC) named the illness EVALI - which stands for e-cigarette or vaping product use-associated lung injury.
At least two Brits are feared to have died from vaping-related lung injuries in the past year, UK health officials revealed.
The medical regulator was understood to be investigating the deaths and has received 244 reports of adverse reactions to the devices.
San Francisco became the first US city to ban electronic cigarettes in a bid to curb underage use of tobacco products.
E-cig manufacturers, Juul labs whose headquarters are in the city say that the move will deprive adults of healthier smoking alternatives.
In June 2018, scientists warned that inhaling flavoured e-cigarettes can damage cells lining the heart and blood vessels, leading to cardiovascular disease, strokes and heart attacks.
Another study warns vapers may be at greater risk of a life-threatening stroke than smokers.
Mice exposed to e-cig vapour for 10 to 30 days suffered more severe strokes, and greater nerve damage than those exposed to tobacco smoke.
While results have yet to be confirmed in humans, the warning signs are there, the researchers said.
The team at Texas Tech University Health Sciences Center said: "Vaping is not safer than tobacco smoking and may pose a similar, if not higher, risk for stroke severity."
Another study said e-cigs could increase your risk of cancer even when there's no trace of nicotine.
The number of under 18s who have tried vaping has doubled in just four years, official data reveals.
Health bosses admit e-cigarette “experimentation” among young people is on the rise.
Officials admit the steep rise means they must remain “vigilant” on youth smoking.
How many puffs of a vape is equal to a cigarette?
It is estimated that an average smoker finishes a cigarette in around 10 to 15 puffs in 5 to 8 minutes. Looking at a vaper using a 5% nicotine e-liquid in a basic refillable pod device, they may need somewhere between 30-50 puffs to ingest a similar amount of nicotine
Can your lungs heal from vaping?
It's reported that lung function starts to improve two weeks to three months after quitting.
From one–12 months after quitting, symptoms such as coughing and breathing problems should improve as lung structures heal.
What happens when you go from smoking to vaping?
Switching to vaping significantly reduces your exposure to toxins that can cause cancer, lung disease, and diseases of the heart and circulation like heart attack and stroke.
These diseases are not caused by nicotine, which is relatively harmless to health.
However, vaping is not risk-free.
Is there a safe vape to quit smoking?
There is no such thing as a safe e-cigarette that can be used to quite smoking - although they are less harmful.
Many smokers use vapes to stop smoking cigarettes but then try to stop vaping altogether.
Is vaping classed as smoking?
From a health perspective, some medical professionals do not class vaping as smoking.
However, when it come to insurance, if you have used any tobacco products in the last year then you are classed as a smoker.
Is vaping harder to quit than smoking?
Many people who are trying to quit vaping find it just as hard as when they were quitting cigarettes.
It depends on the individual as to how hard someone may find it to give up vaping completely.
Many find that when they use vaping to give up cigarettes, that they continue to use vapes as an alternative rather than stopping altogether.
Radio and TV star Jordan North started using e-cigarettes to quit cigarettes but found that he became reliant on the former.
He had filmed a documentary for BBC Three where he explores the risks of vaping.
