Sub ohm ========health hazard

[Tygerlovesdeb]

I am sure there are some who subohm to create bigger clouds. For me, it is the taste of the juice. I have different ohms for different juices if that makes sense. I don't like an overpowering taste on some juices, so I use more wattage on them to tone it down. Other juices that I want to bring out more of the flavor, I lower the wattage to reduce the heat. Though I don't even give a thought to the actual wattage, I have three different subohm levels I use for three different juices.

Personally, I think people make way to much fuss over the dangers of subohming. There has only been one recorded incident where someone got hurt from a battery exploding and from what I read about the incident, it sounded more like a bad battery than the ohns the guy was vaping at. I have gone all the way down to as low as .04 ohms. When I do go that low, I only hit on the same battery a maximum of 15 times which is probably way more than I need to.

It stands to reason that subohming is probably harder on your lungs. When you get down below .3 ohms the vapor gets pretty hot. Anyone who subohms as probably had hot oil come out of a vent hole and burn their arms or leg. After a while you don't even notice the heat anymore. I don't know the effects of hot vapor on the lungs. Who knows, maybe one day a doctor will come out and say it has some kind of health benefit.

I am sorry, it is completely wrong description of boiling (and atomizing) process.
Liquid boils as a whole thing, its components does not boil as separate entities.

no it describes exactly what is happening.the vapor produced by the water atomizes the other
ingredients.
just like a pump spray or the compressed gas in an aerosol can.the good Dr who
invented the modern e-cig used a sonic vibrator to atomize the juice.
PG and VG are used to evenly disperse the nicotine and flavors and keep them dispersed.
they were never intended to be the atomizing force.

Exactly no.
Water is of no importance at all.
May be we need a new thread to discuss boiling and vapor production.

I'm no expert on sub-ohming, but I think you may be doing it wrong...

its exactly how cigalikes work.you don't think there heating PG or VG to
over 300 degrees F? it would melt the cartridges. anything more advanced than a cigalike
is just a glorified version if a cigalike. same process,just more of it.

It does not burn even cotton, which is really close to a hot coil.
So yes, temperature may be going above 300 F. (I did not found phase diagram, so I do not know boiling temperatures of mixture).

The boiling point for our typical PG/VG/water blends is around 380 F, depending on the actual blend.

I'm thinking out loud.

"Vapor" is a produced by process called evaporation. Liquids evaporate faster as temperature increases. Liquids have different propensities to evaporate and have different boiling points. There can be evaporation without boiling. Air combining with the vapor cools it but I also suspect most of the vapor produced by the coil never reaches anywhere near the temperature of the coil. The vapor entering our mouths is not 380 degrees or even close to that. This is a physics question I'm not so sure about but it might be useful to understand it better.
