JFC no, formaldehyde is NOT an ingredient in vape fluid.
It is propylene glycol and vegetable glycerin with artificial flavors and nicotine. Essentially a miniaturized fog machine, with nicotine.
I’m not claiming that it’s healthy, but my god I can’t count how many times people have told me I’m vaping embalming fluid. I am a funeral director for god’s sake, I know what formaldehyde is.

Had a lung tumor, not your typical lung cancer, but a carcinoïd tumor. doctors says I might have that since I’m a child, it grows very very slowly.
My right upper lobe got completely obstructed over time without me knowing.
One day I did a control for some pain that were unrelated, they called me the same day to announce they found something weird.
5 month later, got my upper lobe removed, got some minor side effects of the surgery, but I’m able to do sport and I’m quite well recovered.

Why do my lungs feel way worse after I quit smoking? It’s like they’re a lot tighter.

Formaldehyde isn’t in my vape juice

9:33 formaldehyde is not in vape juice. Nicotine isn’t a problem, other than addiction and delivery method. The unknown is the flavouring. Most seem ok so far, but no one knows long term if there is any issue. Other wise it’s just propylene glycol and vegetable glycerin. A lot of the scary stories are kids who vape illicit weed carriages that are adulterated. And this gets mis reported.

This has to be a personal record for me. I kept manually breathing for almost 22 minutes.

Can you please please have a thyroid specialist answer thyroid questions? I think a lot of people don’t even know about their thyroid and its tremendous functions in our bodies.

Yo earthlings can you ask a simple question without pointless and dumb-sounding profanity.
@Idiot-the-feeble
May 1, 2026 at 8:41 pm
I think hiccups are like burps without the gas, it’s like tryna get the last bit of ketchup out of the bottle. Cause hiccups can be caused by indigestion and now I just learned this is an actual scientific hypothesis.

0:47 what about blinking? isn’t this the same premises. You automatically blink and then you can manually blink

1:16 is this bc the diaphragm isn’t a smooth muscle like other organs? That’s the only like anatomical/physiological explanation I can think of with my limited understanding
