Hot off the press, results of Dr F study

[scrumpox]

Just my thoughts on this @Diche, although this study proves to me as an experienced vaper that there is no concern., it's the interpretation by others that worries me when they see mods available of a 150w plus.

It may be nothing, but I'm not completely sure this side of the argument is fully laid to rest yet...

I think your concerns about the high power mods is unfounded.
[FONT=&quot]Power levels are NOT associated with high aldehyde emissions as long as vapers use them in normal and not in dry puff conditions. [/FONT]

The study proves what we already knew - dry hits are bad ... very bad. The research findings tell you that the power levels of the mod are unimportant. Dr F has not reported that high power vaping is problemmatic, vaping efficiency is the key. The dry hit is the end product of inefficient or errant vaporisation.

Those at greatest risk will be inexperienced vapers who don't understand their equipment and don't set up the coil, wicking and airflow correctly, bearing their atomiser and mod in mind. Experienced vapers make fewer such mistakes and consequently experience fewer dry hits. Empathy with your gear can reduce the dry hit count to nil.

It's for another debate perhaps, but I believe that temperature control is the way forward for newbs particularly. Arguably, they'll never learn to set up correctly with this safety net in place but if they persist with a temp controlled set up they'll not need to, from a safety perspective.

A second aspect - the ANTZ don't differentiate between styles of vaping - low power or high power - they oppose it on principle. They don't care whether we vape gen 1, 2 or 3 gear, they don't care whether we cloud chase or not. So for us as vapers to be even hinting at division (ie saying the problem for vaping lays with high power mod users) is misguided and detrimental to unity of purpose. We know from the ANTZ's arguments and positions to date that they're selective on facts, prone to making stuff up and have a poor understanding of real vaping practice. If they should suddenly shift their position to attacking not vaping as a whole, but high power vaping in particular, then they'll have conceded significant ground by doing so. The Tobacco Control lobby is unconcerned with details such as these, it's purely about nicotine use for them, in any guise.

I do like Dr F, It's nice to have some accurate research studies to read in among the Tripe funded by Big Pharma every now and then!!!

I've vaping a few months now and believe i had my first dry hit last night - gos am i feeling it today, throat is ripped to shreads and i feel like shite.

Bad bad bad.

Back on Track, just about to read his report - got my 'doctor F voice in my head' reading skill ready.

But one could link high power to increased coil temperature - and he has linked that to increased production of other toxins.

The level to which one ought to be concerned will change when he releases the rest of the study although I'm more concerned about how many anti-subohm threads it will create.

Yes, but excessive coil temperatures can be reached without high power devices or subohm coils ... we all know that you can get a coil to glow red without a wick, juice and airflow to cool it, eg dry burning NV 1.5ohm coils in an Evod using a small eGo battery. Any coil in any vaping device has the potential to reach excessive temperatures ... but not in normal use ... that's Dr F's point here.

The anti-subohm brigade may just looking for scapegoats if it goes tits up. It's divisive, incorrect and unnecessary. The resistance of the coil is just a variable amongst variables. "Subohm" has become a ridiculous umbrella term and an even more ridiculous way to divide vapers.

True dat.

Ok, I will give you the way a PH person could interpret this.

This study demonstrates that an ecig has the potential to produce considerable amounts of aldehydes when used incorrectly. The ecig has no capacity to detect aldehyde production and relies solely on the user to detect and determine that the device is operating within safe parameters.

This raises the question , - do all people detect a dry hit at the same dry hit point /aldehyde production? Or does detection fall within a range?

Within this study 7 people were used and correctly identified a dry hit. -Is 7 a large enough sample size to draw a conclusion across the full vaping population?

Erm, -nope, more research needed.

Now that we have temperature control mods wouldn't it be safe to say that dry hits will be a thing of the past. I think also it shows big tobacco being behind the curve in terms of innovation and safety which bodes well for the smaller companies.

Conclusion
Electronic cigarettes produce high levels of aldehydes only in dry puff conditions.........even in new generation high power cigarettes.


E-cigarettes generate high levels of aldehydes only in ‘dry puff’ conditions - Farsalinos - 2015 - Addiction - Wiley Online Library

Loops notes :high watts in this study=10W

Bloody clickbait.
