AS A YOUTH EPIDEMIC LOOMS, MORE EVIDENCE AFFIRMS THE DIABETES – INSULIN RESISTANCE – NICOTINE – VAPING LINKS
The new evidence predictably reinforces established links from vaping to nicotine-induced insulin resistance to a surging youth diabetes epidemic

From a media report on the original research –
Researchers from the Korea University College of Medicine in Seoul, South Korea, analyzed health data from a group of 179,273 adults through the Korean National Health Insurance Service, according to a press release.
All participants had smoked traditional cigarettes between 2011 and 2012 and then quit smoking by 2018 or 2019, they reported.
To ensure a fair comparison, the researchers paired up participants who shared similar backgrounds, including their age, gender, medical history, existing health conditions and general lifestyle habits.
This process created a balanced group of 32,316 matched participants, who were divided into two categories: complete quitters who stopped using all nicotine products and those who transitioned to smokeless nicotine products, such as vapes.
The researchers followed the participants for an average of 4.6 years to determine whether they developed eye conditions, including cataracts, glaucoma, age-related macular degeneration, diabetic retinopathy and focus-related eyesight disorders. …
Most notably, those who switched faced a 24% higher risk of developing diabetic retinopathy, a condition that damages the blood vessels in the light-sensitive tissue at the back of the eye.
[emphasis added]
That’s a large difference in development of the diabetic eye condition for the group differing only by continuing their exposure to nicotine by vaping.
It should not be surprising.
Concentrations and delivered amounts of nicotine – directly affecting insulin resistance and blood sugar dysregulation – have become many times greater than those delivered by combustible cigarettes. That’s covered here –
Kids, more vulnerable to diabetic risk factors and effects, are experiencing a diabetes epidemic with large surges in incidence of diabetes and prediabetes, seemingly inexplicable – but only if vaping at exceedingly high concentrations of nicotine is excluded from consideration. That’s covered here –

And in contrast to the rest of the world, youth substance use trends, and especially vaping prevalence, have been grossly underestimated by top media and constructed experts.

That’s all.
For now.
