@SimonChapman6 and @AlexWodak were interviewed on #vaping on @abcadelaide this afternoon

Certain misinformation provided during the interview needs to be corrected

'The 95% safer figure is a factoid based on opinion'

WRONG. This is based on comprehensive reviews by @RCPLondon and @PHE_uk. It is consistent with the substantial reduction in toxins, the reduced biomarkers and improved health in smokers who switch

'Long-term risk. It took 40 years to find out the effects of smoking'

Science has come a long way since then. Smoke contains >7000 chemicals, vapour <300. Chemicals in vapour are mostly <1% concentration in smoke. @RCPLondon says the long-term risk is <5% risk of smoking.

'We are waiting to be sure they are effective'

Not only is vaping the most popular quitting aid it is also the most effective. Vaping is more effective than #NRT and has accelerated the decline in smoking rates in the UK and US

'It will be easy to get nicotine under the new regulations'

NO, It will be very difficult. Doctors must

▪️apply for approval to prescribe nicotine
▪️engage an import company to import it
▪️company sells to doctor
▪️doctor sells to patient Image

Everyone agrees young people should not #vape or smoke
However, the current fear and panic about youth vaping is not based on the evidence, according to our paper published today in @ijdrugpolicy
Co-author Prof Wayne Hall

colinmendelsohn.com.au/youth/
🧵2/9
In adolescents who have never smoked most #vaping is occasional and short-term
Frequent vaping in this group is uncommon: 1-2% in most international surveys eg England ⤵️ Image
🧵3/9
Rather than being a gateway into smoking, #vaping is diverting young people AWAY from smoking overall. Increased vaping is accompanied by an accelerated decline in youth smoking
Eg in the US ⤵️ Image

41 leading tobacco control and addiction experts from Australia and NZ have written an open letter to Health Minister @Mark_Butler_MP asking him to reconsider the proposal to further restrict access to nicotine #vaping
colinmendelsohn.com.au/butler-4/
🧵2/4
Their concern is that
“this approach will have serious and harmful unintended consequences for public health, will slow the decline in smoking and will ultimately be unsuccessful”
🧵3/4
The experts say that "a well-designed adult consumer regulatory model is most likely to achieve the two goals we all seek, i.e., making vaping products available as a quitting aid for adults who smoke and minimising access by young people"

WARNING. AUSTRALIAN nicotine is extremely toxic!

According to @TGAgovau's latest advice

'Nicotine is a poisonous substance'
'There are significant health risks associated with nicotine use

We should get the safe nicotine that other countries use...

Appalling journalism @dailytelegraph

'Vape Craze, A Real Drag' 11 June 2021

Gross misinformation from 2 anti-vaping activists. No pro-vaping expert consulted to challenge or correct

No response to my letter to editor to fix it, so here are my corrections

Pls share

1/ 'Switching has not been shown to reduce proven health harms’

Response
NASEM 18-2: 'There is substantial evidence that completely switching from ... cigarettes to #ecigs results in reduced short-term adverse health outcomes in several organ systems'

Good to see some balance in this article with some commonsense from @AlexWodak

However still some serious misinformation
FYI @janehansen2000
1. #vaping is not a Big Tobacco plot

-BT did not invent vaping
-Vapes are a direct competitor to cigarettes and are a huge disruptive threat to the industry
-BT is mostly focussed on #HTPs
-If BT switches from #cigs to #ecigs, that is good for public health. vaping is 95% safer
2. Popcorn lung has been long discredited

There has never been a single case of 'popcorn lung' from vaping or smoking, and diacetyl levels are hundreds of times higher in smoke than vapour

@CRUKLondon laid this to rest years ago

1/There is so much wrong with this article

▪️Only anti-vaping views quoted
▪️Extensive misinformation not challenged
▪️No alternative views offered

Can I have a right of reply @Dana_Adele

2/ nicotine is highly addictive

The addictiveness of nicotine depends on how it is delivered. Smoking is highly addictive due to rapid nicotine delivery and other chemicals in smoke. Vaping is significantly less addictive than smoking
3/ doctors should be focused on getting people off cigarettes and nicotine completely

Ideally yes. But many smokers can't quit nicotine and switching to a safer alternative is lifesaving. The focus of #THR is reducing disease, not ceasing nicotine
