In my opinion, I think he was looking for something negative to go on about.
Well, it gave us something to do - so mission accomplished... ha.

I haven't read all the post since I left today, but I assume the good Doc has left us for the moment. I think the funniest part of the whole debate is the fact that cigarettes are not regulated by the FDA.
It is complex because the third component - flavouring - consists of many different compounds. Do you think all of these compounds have been tested? Even though they're FDA approved that doesn't mean they looked at inhalation. Remember diacetyl. For instance, like you say, just because something is consumed, doesn't mean it is absorbed - depending on the way it's consumed, often. Given that, surely you can see a valid reason for listing flavouring agents in e-liquid, and testing their inhalation?He said he had family trying ecigs or something. My only point, if that is true, was to simplify this logically. Either PG is safe to be absorbed into the body at high levels - or it isn't. Any other study of so called "vaping" is silliness, in my view.
This would be far more complex if vaping did not consist of only three components.

They don't use PG in most asthma medications anymore (it may be in some, but none that I'm familiar with). I know in some instances it is either not used at all or they have replaced it with polyethylene glycol (as is the case with Symbicort). Even at that, there may be a difference between a chemical used as a lubricant for an inhaler taken twice a day and our use. Most nebulizer solutions are administered in saline and use cool mist rather than heated, which also makes a difference.don't know about nebulizers but i do know they use PG under it's alternate name in asthma inhalers.
There are different types of nebulizers , but the most common one usues the the Venturi effect(jet nubulizers). A compressor generates a high velocity stream of air which is passed through a thin film of the medication liquid which converts it to a a mist which is delivered, via tubing, to a mouthpiece and inhaled. No heat is used. There are also ultrasonic nebulizers as well(again no heat is utilized)anyone know what is in a nubizier that causes the mist?
