50 years ago, Big Tobacco perfected #MerchantsOfDoubt tactics: Just convince everyone "experts disagree" about smoking risks.

Today, our own health officials claim experts disagree about tobacco #HarmReduction.

...while in reality, agreement is strong & growing.

Note that the 60+ orgs above are obvously a cherry-picked list. The ONLY argument being made here is that there is strong and growing consensus that nicotine vapes ("e-cigarettes") are SAFER than tobacco cigarettes.

Public health officials should stop claiming otherwise.

Welcome to How to Lie with Percentages 101
This seems like a minor point in @FDATobacco Director King's recent Op/Ed in Nature. Here is a quote:

"In 2021, 11.3% of high-school students used e-cigarettes, compared with 4.5% of adults."

It's misleading in 4 ways.
(1/6) 👇Image
(2/6)
First, it's not 2021 anymore. The latest data from the @CDCgov NYTS and NHIS surveys are easily available to the authors.

In 2023, 10% of US high school students vape nicotine "at least once in the past month." And 7% of adults do so "daily or some days."
(3/6)
2nd, why high school? The 2023 average for all US middle and high school students is 7.7%.


7.0% of all US adults vape nicotine as of Q3 2023.


Very similar. How awkward is THAT?cdc.gov/mmwr/volumes/7…

Humans have been burning leaves of the tobacco plant, and inhaling the smoke, for well over 8,000 years now.

It had ceremonial purposes, presumably when nicotine's psychoactive effects were needed: increased focus, attention and memory.

For thousands of years, tobacco leaf smoking was only a thing in the Americas.

In the Old World plenty of people smoked, but not tobacco leaves. THEY smoked cannabis or opium.

Then THIS guy, Sir Walter Raleigh (1552-1618), brought tobacco leaves back to England from the New World.

He was beheaded in 1618... but not for smoking. The Spanish Ambassador demanded it, so King James approved it.

Smoking caught on in England and the Old World. Image

"Middle school use is up."

#FactCheck: MISLEADING. Middle & high school nicotine vaping dropped 61% over the past 4 years. 1.9% of teens vape nicotine daily, so may be 'hooked' (down >50% in the past 4 years).

"More than 1 in 4 teens use e-cigarettes daily."

#FactCheck: FALSE. 7.7% of middle & high schoolers vape nicotine "at least once in the past 30 days."

Of THOSE, 25.2% (1 in 4) vape daily = 1.9%. So 1 in 53 vape nicotine daily. Not 1 in 4.

Consider "the Standard Narrative" *pushed* by tobacco control:

• Whole new generation addicted to nicotine
• E-cigarettes are a gateway to smoking
• Ecig use increased exponentially, especially among teens
• They target teens
• Nicotine harms developing brains

(1/X) 👇🧵👇Image
(1a) Where is this "whole new generation addicted to nicotine"?
In the USA, teen nicotine USE is lower today than at any time in the past 50 years.
#FactCheckMe: @CDCgov and @NIH survey dataImage
(1b) Where is this "whole new generation "addicted" to nicotine"?
The above numbers do not measure "addiction." For that, we need to look at frequent and daily use.

Daily Brain Harm News
15 past-Presidents of the top professional society in tobacco control call "nicotine brain harm" claims "speculative" because there is no human evidence.

Yet @CDCgov continues to tell the public "nicotine harms developing brains" is a known fact.

THREAD 👇Image

How do we sort that all out? First, we should consider what actually can, tragically, cause permanent life-long harm to developing brains.

- under-nutrition
- toxic stress factors (neglect, abuse, loss of parents,
and exposure to violence) Image
(3)
Next, we should consider the evidence "nicotine harms developing brains":

Young rats have subtle reversible brain changes (not necessarily harms) that are comparable to changes caused by caffeine.

This is the evidence used to claim nicotine is a "brain poison."

This VERY common "mistake" is a direct consequence of the way CDC & FDA present teen vaping data.

It confuses journalists, the public and members of Congress.

@CDCDirector Walensky & @FDACommissioner @DrCaliff_FDA: I demand you STOP reporting Daily Use as a % of 'current use'.
(2)
Here is example #2 @CDCDirector Walensky and @DrCaliff_FDA. Another "trusted" source telling the public 1 in 4 teens use ecigs daily.

The reason this is happening is clear: You present the data in a deliberately confusing way (daily use as a percentage of 'current use').
(3)
Example #3 @CDCDirector Walensky and @DrCaliff_FDA. The way CDC and FDA communicate US teen vaping numers to the public is demonstrably confusing.
