Doctors Show How Vaping Thc Damages Lung Tissue

I just came across this article, claiming that even nicotine-free e-liquids contain lung-harming substances like acrolein:

What I hate about articles such as these is that they're almost always posted with some scary headline and usually end up saying there isn't a proper research into topic or they're awaiting further investigations.

Anyhow, can anyone comment on what 'acrolein' is? I've heard of formaldehyde being created when vaping on high wattage, but this is the first time I hear of acrolein.

Any thoughts on this study?

If I understood correctly, despite mentioning the THC issue, they are also trying to imply that regular, legal vaping may be the culprit for many of the lung illnesses that have came up recently.

Finally an honest article on the vaping hysteria!
This is in today's Washington Post  

I quit smoking after 42 years of them a little over 6 months ago. Landmark event for me. My ability to quit I owe to vaping...thank God for that crutch. Maybe I have other issues going on, but I could swear that more I vape the shorter my wind becomes. I figure no sense going to the doctors because most of them are thumbs down on vaping, but would like to know if others have experienced this. I'm on 3mg nicotine 50/50 juice @ 10.5 - 11.5 watts. I am a chain vaper, if you see me, you see me with my mod and atty. Any feed back?  

CDC Confirms 8th Vaping-Related Death Eighth death linked to vaping as illnesses surge around the United States US vaping illnesses top 500, Missouri man is 8th death Desensitized yet?  

I am very curious. There is a LOT of talk about not knowing the long term effects of vaping. It has only really been around for a little more than 10 years.

Who here has been vaping the longest? I have been vaping for about 8 years. I have seen no bad side effects or health problems. It has dramatically improved my breathing, endurance, and just generally feeling much better.

Do we have anyone that is in the 10+ year category? 10+ years won't make the doctors happy but I think that is long enough to start picking away at the "don't know long term effect" garbage.  

So I've been mouth to lung vaping since I started vaping. Started at 24 mg with the Halo Triton and when I upgraded to the iStick and the Nautilus I lowered my nicotine down to 15 mg. It's been fine.......getting enough nicotine so I don't crave analogs, not getting too much nicotine so that I start feeling sick. Throat hit has been fine and not uncomfortable.

Yesterday I started doing lung hits with the iStick and the Nautilus and with the greater amount of vapor I can produce, I stepped the nicotine down to 12 mg since I also started to get a little lightheaded (I suppose with the greater amount of vapor I am also taking in more nicotine, even though nicotine absorption through the lungs is not supposed to be as good as through the mouth and nose). The juice that I am using is also a 70VG/30PG mix as compared to the 50/50 I was vaping before. However this morning I woke up with an irritated throat and the vape (even when switching back to mouth to lung) feels more harsh.

Do I need to step down the nicotine level even more to 6 mg? Is this normal when going from mouth to lung to direct lung hits? I'm not subohming, so I didn't expect that I would need to drop it down that much. I'm afraid that if I drop it down too much, then I'm going to have more cravings and will need to vape constantly.  

Just came from my dentist. This is my 2nd cleaning since I stopped stinkies on May 26, 2014 and got on the VAPE. I am DELIGHTED to report to my ECF FAMILY that the dental hygienist as well as my dentist told me my OVERALL gum tissue health has MARKEDLY IMPROVED

I mean how good is that. Many thanks to ECF and our community for providing the knowledge and the power to stay quit and enjoy vaping. Thank you one and all!  

Hello to everyone,
I always had doubt about cotton and I was investigating it. I talked to few doctors and they all say the same thing in my country but when i talked to other doctors from other countries I couldnt get much information and I believe the reason is explained well in the following message that I received from a doctor.

I'm calling every doctor and people who use cotton in ecig as a wick, also aspire company as they started to use organic cotton in every coil they have.

Today I have received a scientific explanation from the doctor and I'm translating it.

---------------------------------------------------------------------------------------------
First of all this sickness usually not known by US or German doctors, because they have high hygiene in their cotton factories. This issue is known by 3rd countries like Turkey and other countries where there is no hygiene in cotton factories and employees inhale cotton dust.

It is under pneumoconiosis category and the sickness name is Bisinosis. The doctor reported; every year many employees who are working in cotton factories that are lack of hygiene and filter getting bisinosis sickness and dead from bisinosis, because of inhaling cotton dust for a long time.

He said it is not important if it is organic or not, the important thing is the particle of cotton. The particle of a cotton is 0,5-5 micron. The problem is the cotton gets burned even with temperature controlled devices because the cotton fire range is so low and this can be detected with a microscope not by eyes. The cotton does not need to be burned and turned to black color that can be seen by eyes. Its particles are burning even with a very low heat at 3.0v and wet with liquid, that can be seen under the microscope only.

When the cotton is burned, that cotton micron diameter goes down from 0,5 to lower diameters and turns to a dust which can be seen by microscope only. Those burned cotton dusts goes to the lungs and stays there because the human body is surely unable to absorbe it as it is not organic anymore because of burned particles.

He clearly state this; The cotton dust cannot be absorbed in lungs and will result bisinosis in time which will lead to dead for sure he says. If it was tolareted and absorbed, there wont be a sickness called bisinosis and people who are working in cotton factories wouldnt die in the past from bisinosis sickness.

He also add this, people working in cotton factories inhaling cotton dusts which is not burned already causes bisinosis sickness, I cannot imagine what burned cotton dust is going to do because its micron diameter is smaller than normal cotton dust due to fire damage, maybe those employees getting bisinosis between 10 -15 years but in ecig case, burned cotton may speed up the process of the sickness.
---------------------------------------------------------------------------------------------
Final Notice from the doctor; Above information makes cotton %100 dangerous to inhale and will result bisinosis in time soon or late even with temperature controlled devices. Employees are working in 3rd country cotton factories where there is no filtration are not inhaling warm cotton and they are already getting bisinosis, again this sickness is known by 3rd countries which cotton factories have no hygiene and filtration. I hope this will make sense, for everyone who use cotton in ecig.

So, the doctor explanation is above and enough for me to not to use BVC coils anymore also cotton unless someone make a different scientific explanation to above doctors information and make it wrong.

It is clearly understandable if you use cotton in ecig, no filtration(you cannot filter it as the particles can be only seen by microscope), it will surely will cause bisinosis one day as you are inhaling cotton particles in to your lungs which is surely not absorbed.

What bisinosis is: Byssinosis - Wikipedia, the free encyclopedia
(Byssinosis, also called "brown lung disease" or "Monday fever", is an occupational lung disease caused by exposure to cotton dust in inadequately ventilated working environments)

UPDATE:
I just received a second opinion from another DR, MR Farsalinos send me the following email after I ask him the above explanations.

---------------------------------------------------------------------------
First of all, i have a question for you. Has the doctor who told you about byssinosis informed you about silicosis? It is a disease which is caused by inhaling silica dioxide fibers. That means, silica and ekowool fibers used as wicks (alternatives to cotton). Silicosis is even more common than byssinosis.

Byssinosis is almost exclusively observed in workers in cotton processing. So, most likely it is dust from the spores of cotton which cause the disease. Processed cotton does not have spores or other type of dust. It is possible that cotton fibers may cause a disease, which is not byssinosis, and i found only 1 case report of someone who developed some form of disease due to cotton fibers. But he was exposed to huge levels of cotton dust every day for many years.

I find it unlikely that the cotton wick will cause byssinosis, but of course none can be 100% sure. However, i think that silica and other alternatives may be equally (if not more) problematic. So, please stay calm.
---------------------------------------------------------------------------

So, second opinion is clear my mind now and made me calm.
