[ismahabib]

Although PG can be toxic at HUGE levels (more than one could consume), it is safe in the quantities that we, as vapers, consume. PG is the same stuff used in asthma inhalers and fog machines.

Where is your information on PG being toxic? I know it can be an irritant for some people, not not toxic.

Although PG can be toxic in HUGE levels, generally they are safe. PG is the same stuff used in asthma inhalers and fog machines.

LD50 for PG is around 20 g/kg (http://www.thermo-dynamics.com/pdfiles/MSDS/Prop_Glycol_USP_EP_msds.pdf).

Even a quite small person, 50 kg, would have to ingest a liter to reach that point. A fairly heavy vapor consumes order of magnitude 6 ml/day, far below the toxic threshold.

I've not heard of any risks relative to liver, kidneys, lung, at least at sane levels. PG was historically used as a disinfectant in hospital ventilation systems, and has been used as the carrier base for inhaled anti-rejection medications used by lung transplant recipients. (search on cyclosporine)

Basic sensitivity is a separate thing. Some people are sensitive to Glycerine (aka VG), some to PG, some to various flavorings, the same as people are sensitive to these items in food products or skin lotions.

Propelyne glycol is the same stuff as in asthma inhalers, fog machines and mouthwash.

Vegetable glycerine is the same stuff as in sore throat medication. Also, as a suppository it can be used as a laxative (Seek medical advice! Do not try this at home!)

To answer your question more broadly, however, whether or not PVs are 'safe' has not yet been proven. What we can say with a degree of certainty is that they are 'safer' than tobacco smoking. 4000 known carcinogens vs...0, for example! Many people here have reported that their health has improved and medical professionals have been amazed by their changes in lung function, xrays, and other medical conditions.x

Yeah, there aren't enough studies yet and we don't know the long term effects because it is a new product, we'll have to wait years to see if there are any long term effects. But it does look safer than tobacco.

Please put those cancer causing cigarettes down, and start vaping! Where it is not proven to be 100% safe, the alternative is that cigarettes DO cause cancer, emphysema, asthma, and other health problems. They have over 4,000 chemicals, and around 60 of those are known to be carcinogenic. Nicotine is not the problem, it's the tar and other chemicals.

Yes, I'd say e-cigarettes are safer.

Edit: My blood pressure is now 15 points lower than when I was smoking.

Some hospitals occasionally use PG in their ventilation system for sterilization purposes. Also used in some operations.

Post #5 has it, also:

The acute oral toxicity of propylene glycol is very low, and large quantities are required to cause perceptible health damage in humans; propylene glycol is metabolized in the human body into pyruvic acid (a normal part of the glucose-metabolism process, readily converted to energy), acetic acid (handled by ethanol-metabolism), lactic acid (a normal acid generally abundant during digestion),[12] and propionaldehyde (a potentially hazardous substance).[13][14][15]

There are over 4000 chemicals in cig smoke (a lot come about through the burning process); there are over 50 known carcinogens in that group, including the pretty nasty ones known as Tobacco Specifc Nitrosamines (TSNA). At least some eliquid tests have found trace amounts of TSNA, at the level (small) found in approved NRT products (like the patch and nicotine gum); the risk from TSNA increases with the level of them, and in standard eliquid's case it is really small.

Safer, yes; Safe, no, IMO. This is a statistics thing, I would say vaping is a heck of a lot better than smoking, but not vaping is safer than vaping. Vaping is a significant risk reduction, but there are likely at least some residual negatives, if only due to nicotine (which has some benefits as well as some negatives for certain people). On the other hand, given the risks with anything else in life, I'm personally comfortable with vaping, since with it I've broken a 37 year smoking habit.

You are correct about the studies, but if we continue smoking for years until they have the answer about e-cigs, we'll all have cancer from the analogs for sure.

On the other hand, they can't even decide about eggs, one day they will kill you, the next day, they're healthy. S

OK , so who consumes 20 kg? If one drinks too much water, it can be toxic. Are you trying to tell people not to vape?

You said it was toxic on HUGE levels. You still need to prove that.

A far-sighted ill tempered elephant?

As far as proving anything, no. Semantics are naughty and my nipples are still sore from last night.

Or, try this: Grab a sheet of clean white 24# 96% brightness paper. Cover half of you statement in post #13. Read it 12.6 times. Now do the same, but cover the other half of your statement and read it 6.8 times. Repeat until it makes sense.

I'll be here all week. Don't forget to tip your waitress. And for * supreme being's* sake, quit drink so much water! It's toxic...

To clarify, and to make sense, your own post............ PG is Toxic on HUGE levels, but generally safe. Does that make sense?

I love you. I love so much, i will edit my post to clarify. I'm at work, so it may be a minute.

[Robino1]

Yes it does. Almost anything is toxic in huge amounts. Maybe he should've said if ingested in huge quantities. Hubby is a literal person also and he'll nitpick the hell out of my ambiguous generalities.

Don't take things quite so literally.

Totally safe?

There have been no difinitive studies...

But who cares!

The real question is inhaling vapor safer than inhaling the 4,000+ chemicals and carcinogens in Cigarette smoke?

Hint: the Answer is YES.
