Does Propylene Glycol Dislodge Tar in Lungs?

I don't care about cleaning my lungs out with soap
I just want my back to feel like it hasn't been hit by a freight train (extreme muscle soreness)

Bob, you should also consider that most of the bacterias we have in our body are good ones, our body need them, very few of them are bad ones, killing all of them doesn't sound that great...
try to imagine your doctor giving you some pills for a bacterical infection to be taken for 10 days, and you continue to get those chemical pills every day for the rest of your life... mmh it can't be good.
Also, is PG really an anti-bacterial? it was 'suspected' to be a possible germs/bacterias killer in a 1942 experiment with chimps but this potential doesn't show up in more recent studies for what i read on the internet.

anyway both of them (PG,VG) are toxicant 'suspects' as you can read here for PG:
PROPYLENE GLYCOL

and here for VG:
GLYCERIN MIST

and here there's a database search for all known chemicals, just type the name of the chemical and all about it will show up:
Chemical Profiles

many says Gliceryn (or Glicerol) is safer than PG as you can read here for example:

taken from a UK based Laboratory Test for Totally Wicked E-Liquids

"The primary aerosol forming solvent (Propylene Glycol) used in the preparation of the nicotine
solution is listed as a suspected respiratory toxicant. ‘Pillbox 38’ should look at changing the aerosol
forming solvent from the suspected respiratory toxicant ‘Propylene Glycol’, to an even safer solvent
such as Glycerol. "

and (on recommendations paragraph)

Pillbox 38’ should take a Proactive look at replacing the Propylene
Glycol component completely with an alternative such as Glycerol, in
the event that the solvent becomes added to the list of respiratory
toxicants in the foreseeable future

on the other side somebody says that PG is safer than Gliceryn as VG can produce Acrolein when burning...

in the end, what's safer?
i don't know, anyway i believe inhaling PG and VG is for sure 1000 times less toxicant than analog smoking and like Bob says i believe we all need more tests and studies to be done all over this.

FDA posted their findings today on e cig testing. I would link but I can't as im too new. What do you all think?

I smoke for years, off and on for about forty. I had xrays done every couple of years. My doctor was a little disappointed because I smoked and they came back clear.
I think that is the biggie here. If your lungs were clear when you made the switch, of course you aren't going to cough anything up.
Just be glad, if you are coughing stuff up because that probably means you had tar building up in your lungs and now you are clearing them.
Just remember, this is my opinion and not necessarily what is happening, but I hope so.

I wonder if anyone commenting here uses VG instead?

I was diagnosed with COPD several years ago. When I quit analogs and started vaping (PG base) in March, for the first month I coughed up so much crap that it was sometimes scary. Especially in the morning after a normal nights sleep I would wake up and feel like I was drowning in it until I was able to cough it all up (gross, I know).

Then, little by little, my smoker's hack disappeared completely and I only occassionally cough up small amounts of phlegm. I must admit that the grossness of the first month clearing process was outweighed by the relief that my lungs felt afterward.

Personally, I think breathing the warm, moist vapor HELPS loosen all of that crap. Once in the ER when I couldn't breath the first thing they did was give me a mask to breathe warm, moist, medicated vapor and it also made me hack up a lot of nasty crap.

My doctor listened to my lungs at my last visit and was delighted that my airways sounded clear. I told her I was vaping and she had no problem with it because it's working.

Note: I smoked for forty-two years and was at two plus packs a day.
