There’s a lot of US based anti vaping on Reddit.

David Nutt (who is famous for wanting a review of a lot of drugs) summed it up well.

Written by Professor David Nutt: Vaping of nicotine plus or minus flavours is potentially one of the most important health advances in the history of medicine because cigarette smoking is the largest preventable cause of premature death worldwide. For this reason the UK, led by PHE, truly leads the world in using vaping to help smokers quit and to help minimise young people becoming hooked on cigarettes.

Perversely most of the rest of the world, and the WHO, take the opposite view. These new products severely criticised and demonised. The reasons for this are a complex mixture of politics, self-interest from anti-tobacco lobby groups and puritanical absolutist hatred of recreational nicotine, even when it is of little harm as when vaped. There is also some suggestion that the pharmaceutical companies that profit from selling medicines to aid quitting cigarettes see vaping as a commercial threat. And at the back of all this is the unfounded rather paranoid belief that vaping is a “big tobacco” invention to increase tobacco use, which has been falling in recent decades. In fact most vaping supplies come from small producers and it is the success of these that have attracted some big tobacco companies e.g. Altria into the vaping market.

The ultimate absurdity of the anti-vaping position is the US decision to classify all vaping products as tobacco even when they contain zero tobacco or nicotine. This serves to distort the data on youth smoking in the USA so that the major vaping-induced declines in youth cigarette use are hidden.

What is worse is the way many so-called scientists, medical experts and journal editors, have deliberately distorted the evidence of harms of these new products to the benefit of cigarette sales and to the detriment of smokers health. This subversion of the scientific process has had the effect of scaring many smokers away from potential life-saving alternative products and in some countries has already led to their being banned even though cigarettes are sold openly.

Remember a lot of international reports include all sorts of vapes with aren’t sold in the EU/UK.

MYTH 1 - E-cigarettes give you ‘popcorn lung’

One of the most commonly held concerns is that e-cigarettes might cause ‘popcorn lung’. This came about because some flavourings used in e-liquids to provide a buttery flavour contain the chemical diacetyl, which at very high levels of exposure has been associated with the serious lung disease bronchiolitis obliterans.

The condition gained its popular name because it was initially observed among workers in a popcorn factory.

However, diacetyl is banned as an ingredient from e-cigarettes and e-liquids in the UK. It had been detected in some e-liquid flavourings in the past, but at levels hundreds of times lower than in cigarette smoke. Even at these levels, smoking is not a major risk factor for this rare disease.

MYTH 2 - E-cigarettes aren’t regulated and we don’t know what’s in them

The UK has some of the strictest regulation for e-cigarettes in the world. Under the Tobacco and Related Products Regulations 2016, e-cigarette products are subject to minimum standards of quality and safety, as well as packaging and labelling requirements to provide consumers with the information they need to make informed choices.

All products must be notified by manufacturers to the UK Medicines and Healthcare products Regulatory Agency (MHRA), with detailed information including the listing of all ingredient
