The claim, "nicotine harms developing brains" first appeared in the 2014 US Surgeon General Report, "The Health Consequences of Smoking." Is this harm claim true?
Action on Smoking & Health UK is a respected evidence-focused non-profit with no industry ties. ASH UK disagrees with this now-widespread harm claim.
And 15 past-Presidents of the world's top professional society in the field of Tobacco Control agree with ASH UK. They call the "brain harm" claim "speculative" because there is no human evidence.
I have to point out: (1) If nicotine harmed developing brains, 1 in 3 living US adults over the age of 40 would have brain harms from smoking in their teens. THEY DON'T. (2) 60% of young men returning from WWII would have had brain harms from smoking cigarettes in their K-rations. THEY DIDN'T.
490,000 every year in the United States. Year after year after year. 8 million deaths worldwide, 80% of them in low- and middle-income countries.

When people die from smoking, it can look like this. NOT a good way to go.
IF we know something is safer than cigarettes
AND helps people quit smoking
THEN we are ethically obliged to make it more
Affordable, Acceptable and Accessible to adults
who need it.

In the USA, @BloombergDotOrg spends >$100 million/year on grants to non-profits that misinform the public about TEEN nicotine vaping.
They *push* demonstrably false claims such as:
- "they target teens"
- "gateway to smoking"
- "whole new generation addicted"
#FactCheckMe:
Adult current use (daily or some days)
Nicotine vaping: Q1 2019: 3.9%; Q4 2024: 8.1%
(260m adults) wwwn.cdc.gov/NHISDataQueryT…
Middle & high school “current use” (≥once/month)
2019: 4.5% smoked; 20% vaped (3.7% vaped daily) cdc.gov/mmwr/volumes/6…
2025: 1.4% smoke; 5.2% vape (1.4% vape daily)
(27m teens) fda.gov/media/191376/d…
According to the most recent US @Surgeon_General Report on tobacco, "cigarettes kill 490,000 Americans every year." That seems bad.
The USSG did not write "tobacco products." He wrote "CIGARETTES": Mass-produced combustible tobacco cigarettes.

25 million US adults smoke. Cigarettes shorten the lives of 50% of lifelong smokers by 10 years. 99% of deaths are over the age of 50.
Those deaths are due to:
36% cancer (29% lung cancer)
36% cardiovascular disease
21% COPD

Funny thing happened after nicotine vapes entered the US market 18 years ago. Adult vaping skyrocketed and smoking plummeted.
The media ignores adults and focuses on teen vaping. That went up, down, up and then WAY DOWN to a 10-year low... while teen smoking dropped 90%. cdc.gov/media/releases…
LONG THREAD: What happens when people switch from traditional cigarettes to nicotine vapes?
Does their risk of cancer, heart and/or lung disease increase or decrease? 10,000 scientific studies on e-cigarettes over the past decade. So no shortage of answers.

First let's set the stage. Cigarette smoking is the starting point.
Here is a breakdown of cigarette smoking-related deaths: 36% cancer; 36% cardiovascular disease; 21% lung.
Lung cancer was the first evidence cigarettes kill half of all users.

Cigarettes kill 480,000 Americans every year. They kill 8 million every year worldwide. Super bad.
Nicotine vapes are controversial. They entered the US market 18 years ago in 2007. Long enough to see the impact of product substitution on lung cancer.
Milestones in vaping history
2019: US-only outbreak of vape-related lung injuries caused by adulterated illicit THC vapes.
@CDCTobaccoFree deliberately blames this on legal nicotine vapes. Invents acronym "E-cigarette or Vaping-Related Lung Injuries" (EVALI).

While @CDCTobaccoFree continues to claim "EVALI" is caused by nicotine vapes ("e-cigarettes"), numerous state health departments are telling a very different story.

In mid- to late 2019, SOMEONE alarted local law inforcement to crack down on illicit THC vape cart dealers.
