Why does every Dr fail to answer the REAL mj vape question. We’re not talking about “vape juice”, we’re talking about dry herb vaped, whooooosh. I mean dry herb vaping has been around for several decades, this recent “vape juice/e-liquid vaping” etc needs its own name. Way to dodge the question doc.

If anyone with lung, heart, and airway knowledge can give me some help-
Sometimes my chest and back hurt and feel tight. To the point where it feels like I’m not getting enough oxygen. My muscles hurt, I’m short of breath and confused/have less cognitive function.
Any help?

It’s absolutely maddening that there’s been this war started against vaping when all it does is reduce harm. It’s scaremongering tbh. Everyone freaked out when some vapes were sold on the streets with Vitamin E acetate in them(that’s bad)so they closed down all the vape shops(selling good, Vit E-free vapes). Then it became policy, I’m guessing it’s because cigarettes bring in a lot of tax revenue.

Couple of quick things. As he mentions, the reason oxygen goes in to the blood and carbon dioxide goes out of the blood is diffusion because of the difference in concentration. The gasses want to equalize. Secondly, the hemoglobin has an affinity for carbon monoxide as well as oxygen.

May 23, 2023 at 7:50 pm
While the Doctor did a great job on the lung anatomy and conditions WIRED should have gotten a Toxicologist for vaping as while we don’t have long term studies there is more then enough evidence to say that vaping is just as harmful as smoking (if not more!) because they contain a wide range of chemical additives and flavourings known to damage your lungs. No vape is safe because the chemical industry is almost entirely unregulated and continue to lie to people about their products being safe. Likewise the reason why women develop lung cancer without smoking is fragrances and cleaning products contain carcinogens and women generally are going to have a higher lifetime exposure. To protect your lungs people need to start paying attention both to radion and the air quality around them and cut down on products known to be toxic.

people are not supposed to be vaporizing vitamin e acetate though, which is the only chemical positively correlated with vape induced lung injury. it was put into black market THC vaporizer cartridges because it visually looks like THC oil, but otherwise provides no useful benefit to the product. vitamin e acetate disrupts the lung surfactants and causes the injury, but regular vaping has never been shown to do that.

Atelectis is horrible you breathe in but don’t get air. I know what it’s like to drown in your own lungs. Cigarette smoke shuts down my ability to breathe. Smokers who think they can go outside to smoke and not bother anyone it hangs around you like Pigpen’s dirt cloud. It’s on your skin in your hair and you exhale it when you breath. I agree with the doc breathe air only.

I had heard that the aroma chemicals used in E-Cigs were FDA approved. But since they are intented to be used in food and not to be heated / vaporized, heating and inhaling them is harmful.
Is that correct?

“Vaping”, applied to cannabis, is just as likely to refer to vaping pure flower, not juice cartridges. Vape kits for bud like the Pax 3 and Volcano are very popular. I’d love to see an actual answer to the “vape vs combust” question, since I use a lot of flower personally for epilepsy, but everywhere I look I see the same outdated info that only addresses vape carts, as if vape pens & rigs that use raw flower don’t exist.

I refused to vape or smoke marijuana when those things were getting really popular and my friends would ask me why. I said “I really just don’t think that inhaling that stuff is healthy.”
Then I get “oh it’s natural.” “It’s just water.” “it’s impossible to OD on marijuana.”
Now vape injuries are a thing and one of my friends had to bury his kid who ate cannabis gummies and guess what…? They OD’d. The ER called it cannabis poisoning. Terribly tragic.
We have to be more skeptical about these kinds of things. Remember it took 70 years before doctors and companies started being honest about the fact that cigarettes are bad for us. If money is involved, it’s brand new and it’s going into your body be extremely weary!

This dude is amazing with explaining. He did make a mistake, though: emphysema isn’t synonymous with copd.

Copd is a disease with chronic obturation, usually with emphysema and/or chronic bronchitis.

E-Cigarette of Vaping associated lung injury (EVALI) is not caused by vaping. It is caused by vaping blackmarked vapes with actual oils or vitamin E acetate in them, which will kill you. The traditional bases of propylene glycol and vegetable glycerin will not cause these issues.
This isn’t like a thing that just happens to some people who vape. If you aren’t vaping sketchy products, you won’t get VALI.

If you want to keep a cat, smoke, or vape, by all means, do what makes you happy but at least be honest with yourself that you are exposing yourself to some risks. How bad, how big, or how small is not definite but you know it is there. It’s really comical to see people argue how vaping this versus that is somehow better. Hey, it’s your life, your lungs, do whatever you want with them, but don’t kid yourself. Accept the risk like an adult and indulge anyway.

Back in the late 80s when I was a kid, a doctor told us that breathing wintery air would help when I got an asthma attack, if it was took soon to take another dose of my rescue inhaler. So my mom had me bundled up standing outside taking as deep of a breath as I could of the cold air. It felt like it helped. But, if its worse according to Dr. Kalhan, it maybe have just been a placebo effect then. And now that I have grown out of my asthma. I love breathing in cold air, it almost has a soothing effect.

Thank you for sharing such insightful information, but sadly you haven’t answered the main question. I wished that you went deeper into the effects of vaping.

This is complete bullsh*t. EVALI has been shown to be due to vaping contaminated THC vapes, not typical vaping with nicotine. This is propaganda

Why do they always avoid actually answering the question about vaping. Why dont they just do a double blind trial. Short term effects could easily illuminate the long term. Or make it long term. We been vaping for years.

So this to smokers, they will continue to smoke. My country even forces the companies to print gory pictures of the aftermath of lung related deceases on the packaging, they will smoke. I will never understand.

I had sports induced asthma most of my life but I really wanted to join the military. I started running until I passed out (don’t recommend) until now I haven’t had a single problem with my asthma in 7 years. I may have been misdiagnosed if he is saying you can’t over come it. Maybe?

Stop trying to get people to stop smoking. Literally the air we breathe everyday is worse than smoking. The water you drink everyday is worse than smoking. The car you drive every day is worse than smoking. Your job is worse than smoking. Your electric car is worse than smoking! So let’s stop smoking so we can be murdered by something else!

Young women are usually doing the family’s laundry. Most homes have a washer and dryer in the basement. If many basements have high radon levels, that is probably why young women who don’t smoke get lung cancer.

“Which is safer: smoking, vaping, or marijuana?”
This is one of those questions where the answer is, “Does it matter?” Just don’t smoke, period, and you won’t have to worry about it.

to add onto 11:22, by “they’re in better shape” he means that their hearts, too (not just the diaphragm), are essentially “bigger”/stronger because of the training, and so it pumps more blood to the lungs (and body) than the average sedentary person. by pumping more blood, there is less of a need to breathe just as much as a non-trained person because of the sufficient amount of oxgen.
correct me if i’m wrong. i am still a student but i high-key think i’m correct

He mentioned that a lot of young women who don’t smoke are getting lung cancer and the cause is unknown. Could it be something to do with young women using things like perfume and hairspray and other beauty products, I wonder?

All smoke damages your lungs and it gets worse the more tar there is. The amount of tar is determined by how much oil is burning in whatever you are smoking.
Smoke is bad for the lungs because it is solid, not a gas, and so it deposits in your lungs. Cigars are somewhat easier on the lungs because you don’t inhale the smoke however you get a higher risk of throat cancer in exchange.

You got something wrong about the pulse oximetry 🙃 it’s 2 wavelengths (rarely 3) in the red and infrared and we measure the ratio between them. Also, it can be manufactured with light and sensor side by side, not just across the finger/earlobe
