Truth-telling and "utility" (greatest good for greatest number) are 2 basic principles in healthcare ethics that may come into conflict. For example:

17% of adults are salt-sensitive (more salt => higher blood pressure). 83% can eat as much salt as they like.
THREAD
(2)
The above figure comes from this peer-reviewed paper.
ncbi.nlm.nih.gov/pmc/articles/P…

Now, let's consider how truth-telling and utility come into conflict...
(3)
The dilemma for public health is this: If we tell EVERYONE to reduce their salt intake, this will help the 17% who are salt-sensitive. It may save lives.

But that requires us to violate truth-telling (i.e., it requires public health authorities to lie to 83% of adults).
(4)
Unfortunately, there is no simple diagnostic to distinguish the 17% who are salt-sensitive from 83% who are not.

If you have a family history of high BP, or have high BP yourself, best to reduce your salt intake.

Telling EVERYONE to do so, reduces pleasure, and...
(5)
...and may actually harm the 11% who are "inverse salt-sensitive." For THEM, lowering salt intake may increase blood pressure. The public health dilemma thickens...

SO: How often have you seen or heard public health recommendations to lower your salt intake?
(6)
Clearly, some people in public health are happy to lean into this paternalistic white lie. It promotes the greatest good for the greatest number. I mean, death is far worse than the loss of pleasure from salt for the 83% who don't benefit from this message. Right?
(7)
Which of course brings us to health messages from old-school tobacco control authorities. Demonizing nicotine, like demonizing salt, is one of their key tactics. The words "nicotine" and "tobacco" and "smoking" are often used interchangeably.
(8)
As with demonizing psilocybin, the demonization of nicotine has slowed (and repressed attention to) research on #TherapeuticNicotine benefits.

It's out there, but when 80% of physicians still think nicotine causes cancer, this truth-telling ain't gonna happen any time soon.
(9)
11% of the population may actually experience health harms (higher blood pressure) from the demonization of salt.

The >10% of the adult population with #neurodiversity issues may be harmed by the demonization of nicotine.

As with salt, these harms are ignored. So far.
(10)
Ignoring the harms that result from nicotine's demonization (e.g., fewer smokers use #SaferNicotine patches & gum to quit; fewer adults with #neurodiversity issues benefit from safer nicotine) violates ALL basic priniciples in healthcare ethics.
(11)
A similar paternalistic utilitarian lie surrounds "tobacco." Without a shadow of doubt, switching from smoking to smokeless tobacco lowers your risk of cancer, heart and lung disease dramatically. However, as with salt, public health insists "there is no safe tobacco."
(12)
The claim, "there is no safe tobacco" is technically true, but also a wild lie-by-omission-of-context.

Withholding truth about relative risks is a violation of truth-telling (a basic moral principle in healthcare ethics, linked to informed consent and autonomy).
(13)
So... Here we are:

Public health authorities have grown increasingly comfortable with policies & public messages that violate one of the key moral principles of healthcare ethics: truth-telling.

PROBLEM: When you're caught violating the truth, you lose public trust.

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

Congratulations. You have invited PAVE to tell you about the dangers of vaping. Here's a head's up on what they are going to tell you....

"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).

2019:

"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.
