//Milestones in Tobacco Harm Reduction
Posted 21/09/2020 12:00am
Next Generation Products (NGPs) decouple nicotine from harmful tobacco smoke. Although not completely risk-free, ongoing scientific research suggests their considerable harm reduction potential relative to smoking cigarettes.
By delivering satisfying levels of nicotine while replicating many of the sensorial and behavioural elements of the smoking ‘ritual’, NGPs offer an attractive option to conventional cigarettes for many adult smokers.
They are a viable alternative for the 1 billion-plus smokers worldwide, potentially facilitating the public health concept of Tobacco Harm Reduction (THR): so adult smokers uninterested or unwilling to quit cigarettes can consider transitioning from combustible tobacco to less harmful sources of nicotine.
However, not everybody believes in THR, or that NGPs can play a role in it. Some critics – citing the relative novelty of NGPs and the ensuing lack of long-term scientific data – invoke the precautionary principle and play the waiting game.
This risks wasting time many adult smokers cannot afford.
It’s true even the most established NGP category – vaping – is still relatively nascent; heated tobacco and tobacco-free nicotine oral products even more so.
That said, there’s already a great deal of robust pre-clinical research to suggest these NGPs may be significantly less harmful than smoking.
Indications from short to medium term clinical and behavioural studies [1] are also promising, although we absolutely recognise more research is needed into NGPs and their long-term health effects.
We will continue to do this.
However, when it comes to regulating and facilitating NGP use, we also believe in making decisions based on the encouraging science available today.
Increasing numbers of key actors in public health regulation and policy agree. They’ve started to listen – and more importantly act on – the contemporary compelling evidence, acknowledging and endorsing the principle of THR and of NGPs as viable, scientifically-substantiated, potentially reduced harm alternatives to combustible tobacco.
In the UK, where vaping is both popular and widely endorsed by numerous public health groups – including Public Health England [2] – as a cessation tool, the smoking rate has plummeted. [3] Modelling suggests if other countries adopted this approach, the world would have 200 million fewer smokers. [4]
Now is the time to act. Public health bodies and regulators ignoring the evidence risk preventing millions of adult smokers worldwide from accessing potentially life-saving alternatives.
We urge policy advisers, media and regulators who believe in pragmatic and progressive public health policies to explore our dynamic THR timeline below and act on what the data tells us.

Milestones in THR
In the UK
Action on Smoking and Health (ASH) data shows the number of UK vapers has fallen compared to last year. The charity warns “unfounded concerns about health risks from e-cigarettes may mean thousands of smokers who could benefit from switching completely are missing the chance.”
In the UK
The UK Committee on Toxicity (COT) releases a comprehensive report evaluating the relative and absolute toxicological risks of vaping. When produced according to “appropriate manufacturing standards and used as recommended, as a replacement for [CC] smoking”, the report concludes, vapes are “likely to be associated with a reduction in overall risk of adverse health effects.”
In New Zealand
In a new statement, the Ministry of Health reiterates its position that, based on the current evidence, vapes “carry much less risk than smoking cigarettes” and “are attracting very few people who have never smoked into regular vaping, including young people”.
In the UK
In a country where vaping remains extremely popular, it’s reported the smoking rate has again fallen to 14.1%.
In the US
The first ever heated tobacco product obtains a Modified Risk Tobacco Product (MRTP) order from the Food and Drug Administration (FDA), recognising scientific evidence which suggests it “reduces the body’s exposure to harmful or potentially harmful chemicals.”
In Australia
Recognising evidence that vaping is “considered to be less harmful” than smoking, the Western Australian Parliament’s Select Committee releases a report urging the government to lift the ban on vaping, replacing it with risk-proportionate regulation.
In Japan
It’s found that heated tobacco’s popularity has caused cigarette sales to plummet 5 times faster than before the NGP was available.
In the UK
On its blog, Public Health England (PHE) clears up some of the most commonly misunderstood topics on vaping – including EVALI (e-cigarette, or vaping, product use associated lung injury), youth-use and nicotine. It also refutes the findings of a controversial study, published – and latterly withdrawn – the previous year, which misreported data to suggest vapers had the same risk of heart disease as smokers.
In the UK
Public Health England (PHE) issues guidance to National Health Service (NHS) mental health organisations, recommending “patients have access to vaping products” and that practitioners should consider “provid[ing] them proactively to patients who smoke.”

The Office for Product Safety & Standards launch a campaign on battery safety advice for vapes.
In Australia
For the first time, the Royal Australian College of General Practitioners states in smoking cessation guidelines that vaping “may be a reasonable intervention to recommend” if first discussed with health practitioner and use of nicotine replacement therapies or other methods have failed.
In Norway
Vapes containing nicotine are legalised when the country notifies the EU it’s implementing the EUTPD. In line with these regulations, vapes in Norway must first make an application to the Norwegian Directorate of Health, which reportedly evaluates “whether the product will contribute to tobacco harm reduction”
In the UK
A survey of Directors of Public Health finds they support the use of vaping as an aid to move away from smoking, with 75% of respondents advocating vape use in smoking cessation services.
In the US
The British Medical Journal reports the US’s declining in smoking rate mirrors a rise in vaping, “suggesting that the two may be linked”.
In New Zealand
Evidence “indicates that low-risk, non-combustible nicotine technologies (referencing various NGP categories) can successfully displace smoking and provide a significant dividend for public health”, ASH New Zealand and End Smoking state in their Smoke-Free 2025 report
In the UK
Responding to reports of THC vaping associated lung illnesses (EVALI), Public Health England (PHE) says “we are as certain as ever that e-cigarettes are far less harmful than smoking‘ and the outbreak ‘is not a problem linked to long-term use of regulated nicotine vaping products.”
In the US
The Food and Drug Administration (FDA) authorises the first-ever Modified Risk Tobacco Product order, meaning some specific Swedish snus products can claim that they are less harmful than smoking.
In Germany
The Federal Government Commissioner for Drug Issues releases the latest Drug and Addiction Report. The review finds some studies exist which show vapes may be less harmful compared to cigarette smoke due the significant reduction of toxicants in the aerosol.
In the UK
Public Health England (PHE) says vaping is contributing to a falling smoking rate. In England, 14.4% of adults now smoke, down from 19.3% in 2011.
In New Zealand
Ministry of Health launches a factual vaping website which says “vaping can help smokers quit. That’s a good thing.”
In the UK

In Saudi Arabia
The Ministry of Commerce lifts the ban on vaping products. In the same piece of regulation, it also officially legalises heated tobacco products.
In the UK
Public Health England’s (PHE) vaping report says that whilst experimentation has increased, regular use of vapes by young people who have never smoked (11-18) remains very low.

In the UK
Public Health England (PHE) launches its ‘Health Harms’ campaign, encouraging adult smokers to consider vaping.
In the UK
Following the Select Committee inquiry, the Government says once it leaves the EU, it’s committed to exploring regulatory alternatives to ensure “the proportionate regulation of e-cigarettes”, specifically in areas such as the 20 mg/ml maximum nicotine limit and the block on advertising vaping’s relative harm-reduction potential. It also states it will continue to consider the evidence on heated tobacco, and will also consider reviewing the current ban on snus.
In Canada
As vapes are officially legalised, the government says “vaping is less harmful than smoking” and “switching …will reduce a person’s exposure to many toxic and cancer-causing chemicals”. It also confirms “nicotine is not known to cause cancer”.
In the US
The Center for Disease Control (CDC) confirms that in America – the world’s largest vape market – the adult smoking rate has fallen to its lowest level in recorded history.
In the US
The Food and Drug Administration (FDA) Commissioner states “we must recognise the potential for innovative, less harmful products that can efficiently deliver satisfying levels of nicotine to adults who want them” while preventing uptake by vulnerable populations.
In New Zealand
The Ministry of Health affirms “the evidence on vaping products indicates they carry much less risk than smoking cigarettes but are not risk free‘ and says they believe vaping products ‘could disrupt inequities and contribute to Smokefree 2025.”
In the UK
An Action in Smoking and Health (ASH) UK study finds youth use of vapes is “very low” and “experimentation does not turn into regular use”.
In the UK
The Royal College of General Practitioners issue a statement encouraging GPs to recommend vaping. The position says vaping is “a far safer alternative” to smoking and that the “benefits of ECs [(vapes)] in assisting cessation should not be ignored.”
In the UK
The Science and Technology Select Committee advocates for a ‘shift to a more risk-proportionate regulatory environment, where regulations, advertising rules and tax duties reflect the evidence of the relative harms of the various e-cigarettes, heat-not-burn and tobacco products available.’
In the US
In a whitepaper, the American Association of Public Health Physicians (AAPHP) argues “[no one] ever imagined that there could be a product that could satisfy the urge to smoke for many, if not most smokers, and would reduce risk by 95% or more, without addicting teen non-smokers – while being easier to quit than cigarettes. There is now solid evidence e-cigarettes and related vapour products, snus, the chewing tobaccos currently on the American market, and, more likely than not, the new Heat-not-Burn products are likely to meet these specifications.”
In Switzerland
Based on the growing body of scientific evidence, vaping is legalised.
In the US
The Food and Drug Administration (FDA) Commissioner confirms the potential for “novel forms of nicotine-delivery to provide a potentially less harmful alternative for currently addicted individual adult smokers who still want to get access to satisfying levels of nicotine, without many of the harmful effects that come with the combustion of tobacco.”
In Iceland
The Directorate of Health recognises the use of vapes may be contributing to smoking’s decline.
In Denmark
The Danish Cancer Society’s Cancer Control Project Manager for Tobacco Prevention says vapes “are undoubtedly less dangerous than cigarettes.”
In the US
The National Academies of Sciences, Engineering and Medicine says that while vapes “are not without health risks, they are likely to be far less harmful than conventional cigarettes.”

In Scotland
National Health Service (NHS) Scotland declares vaping is “definitely less harmful than smoking tobacco.”
In Australia
The Drug and Alcohol Nurses Association (DANA) recognise vaping is a “much safer alternative to smoking for those who are unable to quit with conventional therapies” and vapes “are not risk free, but evidence suggests they‘re around 95% safer than smoking”.
In New Zealand
The Associate Health Minister says there are various products ‘including heat-not-burn, snus, moist snuff, dissolvables and inhaled nicotine that may be significantly less harmful than tobacco smoking’.
In the UK
The government embraces vaping in its new tobacco control plan‚ “Toward a Smokefree Generation”.
The US
The Food and Drug Administration states nicotine is delivered through products on a “continuum of risk” with combustible cigarettes being the most harmful, and nicotine replacement therapy the least.
In Sweden
In Sweden, where snus and other oral products have been popular for decades, it’s reported that the smoking rate has dropped to just 5% – the 2040 smoke-free target of multiple European states.
In the UK
The Office for National Statistics announces the UK’s smoking rate has fallen to 15.8%.

The Associate Health Minister announces vaping is legalised, even though official regulation is still being drafted, based on “general consensus that vaping is much less harmful than smoking.”
In Canada
Following public consultation, the Canadian Government’s report “Seizing the Opportunity’ recognises THR. New legislation will allow people to access “vaping products, which expose them to fewer harmful chemicals than cigarettes”. This marks a significant shift from 2009 when Health Canada advised people “not to purchase or use electronic smoking products”.
In Norway
Based on evidence it’s potentially less harmful than smoking, Norway announces it will lift its ban on vaping.
In Canada
Public consultation is opened on a new regulatory framework for vaping products in Canada.
In New Zealand
The Ministry of Health opens for consultation on policy for vaping, recognising the “emerging evidence that e‑cigarette use may substantially reduce the burden of disease caused by smoking”.
In the UK
Action on Smoking and Health (ASH), British Lung Foundation, Cancer Research UK and multiple others agree vapes are “significantly less harmful than smoking.”
In the UK
Public Health England (PHE) says employers should allow vaping in the workplace where possible.
In the UK

In the UK
Public Health England’s (PHE) landmark review finds vaping “[is] 95% less harmful than smoking”, “presents about 5% of the risk” of smoking and doesn’t create a ‘gateway’ to smoking for non-smokers and young people.
In Canada
The Standing Committee on Health reviews the evidence on vapes and finds that they may be “be a less harmful nicotine product, containing fewer carcinogens than combustible cigarettes”, and as such, “could help smokers reduce their health risks, and may help them quit.” It recommends the government create a new regulatory framework, legalising vaping products.
In the UK
The Royal College of Physicians (RCP) says vaping could lead to significant falls in smoking prevalence.
In the UK
Almost a decade since vaping arrived in the country, Action on Smoking and Health (ASH) data shows the number of vapers tripled between 2012-14 to 2.1 million. It also reports vapes are overwhelmingly used by past or current smokers.
In France
The High Council on Public Health endorses vapes as a potential route away from smoking, whilst recognising that they should not also act as a gateway to nicotine use and combustible cigarettes for never-smokers.
In the US
The American Association of Public Health Physicians (AAPHP) endorses harm reduction and argues it should be used “as an addition to current tobacco control policies… in a way that will minimise initiation of tobacco/nicotine use, maximise quit rates and assure that dual use does not increase potential harm to the user.” They also recognise vapes and snus as THR tools.
In the EU
The European Scientific Committee on Emerging and Newly Identified Health Risks review finds “smokeless tobacco products (including snus) are clearly less hazardous than cigarette smoking”.
In the UK
The Royal College of Physicians (RCP) says snus demonstrates significant harm reduction potential, stating it’s “around 90% less harmful to health” than combustible cigarettes).
In the US
The Institute of Medicine’s ‘Clearing the smoke — Assessing the Scientific Basis for Tobacco Harm Reduction’ report recognises the potential of NGPs by stating tobacco and nicotine products that substantially reduce exposure to tobacco and smoke toxicants should be developed and studied to determine any reduced health risks compared to cigarette smoking.
