is there any health hazard by cooking e liquids to hot.I think when you sub ohm you are really cooking them juices real hot.Or am i wrong

I don't think your actually cooking them. It would very much depend on the wattage you use to sub ohm. I sub ohm at say a .6 using 15 to 20 watts and that's not hot enough to cook the liquid. But if you used a .6 at 150 watts I'm still not sure that would be hot enough to cook it. Sub ohm is the resistance of your build .1to.9, that in itself won't make it hot it's depending on the wattage your using that will make it warmer. Those two things combined. So generally no its not cooking the liquid, however you had a high enough watt device, what would happen before you cooked the liquid would be you would burn out your wick. We are vaporizing our liquid as it is with just vaping so I'm not sure it would cook it, like I said the wick would burn out first.
the jury is still out on that.
my opinion is even though the water content of juice is low it vaporizes at a much lower
temperature than PG/VG carrying particles of PG/VG nicotine and flavoring with it.
water starts vaporizing at about 180 degrees.a increase in heat increases the rate
of vaporization.
as long as the wick can supply enough juice to the coils theoretically all
is good.
the newest regulated mods have me concerned.
some regulate temperature of the coils into the +400 degree range.
PG boils at about 370 degrees.i think this may be problematic if
the water vapor can't disperse it before it reaches that temperature,

Sub ohm vaping doesn't have to be a health hazard, but it can be. Only the individual doing the sub ohm vaping can make it safe or a hazard. It's all about knowing how, and sub ohm vaping is NOT for the person that doesn't know how.
The only health hazard in sub ohming is diacetyl, contained in certain flavorings. Diacetyl can be carcinogenic when super heated.
I always make sure the flavorings I buy are diacetyl free. Any decent flavouring sellers should be able to answer any question about diacetyl in their product.

I had to explain this just yesterday to someone else.. When broken down, glycerol turns into two -aldehydes, both of which are bad for you, and known carcinogens.
There is a danger from potentially overheating your juices, it's just unsure whether this danger is immeasurable in the realm of a lifespan, or if it's something that, over time, will have some negative repercussions.
I also worry about diacetyl and the other diketones (diacetyl is just the tip of the iceberg, there is a whole realm of stuff that is questionable to inhale when used in flavorings) but really, a big part of vaping was the flavors. I mostly vape fruit/NET flavors anyway, so I like to think I keep my harmful chemicals down to a minimum. The thing is, nobody really knows yet. Maybe fruit flavors feature more harmful chemicals than diacetyl, or worse, actual cigarettes. We don't know yet. But until evidence proves otherwise, I'mma keep on tootin'.
Diacetyl is a natural substance in several fruits. So are you using natural or artificial fruit flavorings?
I'd say a combination of the two.. MBV likely uses artificial fruit flavorings, while I know that other companies say they use natural flavorings (and really who knows if what they're saying is natural or not). It's kind of a tough draw.
That said, it has been believed/discussed (and I believe it too) that a fruit flavor will have far less diacetyl than that of a "vanilla custard with whipped cream" juice. Then of course, there's the whole other issue of which artificial flavorings are potentially harmful to inhale.. I mean, when you boil it down, there's no "safe" juice, but I like to be as cautious as I can be in regards to what I put in my body.
I'll freely admit, I do have some juices that for SURE have some sort of diketone-situation in them (ie: I have a bottle of Sugar Bear by Cuttwood, and some other creamy-ish juices.. Nana Cream by Bombies) and I do vape them from time to time, but since I learned about the presence of diketones and the lack of knowledge that science has on the whole topic, I have really REALLY tried to limit the amount of creamy juices I vape. The only time I'll have Sugar Bear is if I have milk but no cookies, and the only time I vape Nana Cream is when I'm really craving it (cause it's so damn good).
A new study verifies the lower risk-potential of e-cigarettes but identifies an avoidable risk
Dr. Farsalinos' study about e-liquids containing diacetyl (and other diketones) has a link to a study published in the nicotine and tobacco research journal about the effects of certain diketone inhalation. Both his and the linked study are interesting reads.
I think Farsalinos is in the process of raising funding to further study the effects of temperature on e-liquids - in particular the effects of high wattage vaping.
So as usual, the answer is, we don't know yet.
So many links to choose from.
This might be of some interest.

vaping, when it comes down to it, is a simple matter of thermodynamics of liquids and their vaporization point. No matter how much energy one throws into the mix, that constant doesn't change, given the same air pressure.
True, if one can't wick enough juice to supply the greater demand, or supply enough air to move the vape flow and keep the heat down, then yeah, things can get nasty depending on fiber used, cause then ones not vaping but burning the wick, and or super heating the vape atmosphere inside the atomization chamber. , which can produce some very nasty chit that have no doubt ain't good.
frak things up and you be smoking and not vaping, and as we all know, smoke bad, vape good
or something like that.
Vape long and Prosper.!!!

It depends on the temperature.
When people use thick wire, they end up with lower ohms, but they need more power to get up to temperature.
