Fixed - English 101 was not my strong suite.... If you cant tell.
I hate to be a Stickler of Semantics. But the RCP Didn't say this...
"The RCP announcement that vaping was 95% safer than smoking..."
That is what Many People heard when RCP they read this...
"Although it is not possible to estimate the long-term health risks associated with e-cigarettes precisely, the available data suggest that they are unlikely to exceed 5% of those associated with smoked tobacco products, and may well be substantially lower than this figure."
... Or Repeated when someone else Posted that the RCP says that Vaping is 95% Safer than Smoking.
This is exactly why I am asking for feedback! Thanks.
"The RCP announcement got widely publicized as meaning that vaping was 95% safer than smoking, however the detail and context of the entire report has not been talked about nearly as much."
My original offer of a beer and a sandwich is now conditional, based upon no violence toward myself and the Nova stockpile. You may however be required to rebuild Nova heads with rayon until your fingers are worn down to nubs.
Best Pratices to avoid high temps on VV/VW mods.

Context:
The RCP announcement got widely publicized as meaning that vaping was 95% safer than smoking, however the detail and context of the entire report has not been talked about nearly as much.
From the Royal College of Physicians, 11 St Andrews Place, Regent's Park, London NW1 4LE
"E-cigarettes and long-term harm - the possibility of some harm from long-term e-cigarette use cannot be dismissed due to inhalation of the ingredients other than nicotine, but is likely to be very small, and substantially smaller than that arising from tobacco smoking. With appropriate product standards to minimise exposure to the other ingredients, it should be possible to reduce risks of physical health still further. Although it is not possible to estimate the long-term health risks associated with e-cigarettes precisely, the available data suggest that they are unlikely to exceed 5% of those associated with smoked tobacco products, and may well be substantially lower than this figure."
Please note the part highlighted in green. What they are saying is that there is "probably" more we can do to make vaping even safer!
Also note this statement from the University of Cambridge Cancer Institute:
"We also know that different users use different devices and liquids. So it could be that some are safer or more harmful than others. And people also use the devices in different ways. So further work needs to be done to understand these differences, so that each vaper is using their device as safely as possible."
Now, two new studies have come out by Wang and Guiss that suggest that carcinogens (like formaldehyde) start getting produced at high temperatures. I have proven, in some of my other blog posts, that our coils can indeed reach these temperatures quite easily (without being Dry Hits).
IMHO, the best way to avoid high temperatures is to use a TC mod and set the temp below 450f (ish). However, if you dont choose this option for whatever reason, I have attempted to compile a set of "Best Practices" that a VV/VW mod user can employ to help keep their temperatures at lower levels.
"Best Practices"
Using these "Best Practices" will greatly reduce the probability of venturing into the questionable higher temperature ranges.
There are actually about 18 variables that affect coil temperatures in a VV/VW mod. A major one is air flow across the coil. Please see this blog for more info if you are interested.

"Best Practices"
- Avoid Chain Hitting
- Chain hitting a non TC mod will definitely, and sometimes very significantly increase the coil temperature, regardless of voltage or wattage settings. I have proven this with direct thermocouple measurements. What happens is the coil doesnt get a chance to cool between chain hits, so subsequent hits are already starting with a preheated coil. The more chain hits in a row, the hotter the coil will get each time.
- Diligently replace/clean your coil when they get gunked.
- Gunked coils inhibit heat transfer, and the most common reaction is for a user to increase their power to compensate for the weaker hit, resulting in higher coil temps.
- There is also data that suggests that burning the carbonized junk on a coil gives off its own set of extra nasties.
- Juices with high percentages of flavoring, certain specific flavors (often darker ones), and high levels of sweeteners, are known for gunking coils faster.
- If your hit seems to be getting weaker, check your coil for gunk.
- Gunked coils inhibit heat transfer, and the most common reaction is for a user to increase their power to compensate for the weaker hit, resulting in higher coil temps.
- Ensure good coil saturation via good wicking
- If you starve a coil for juice, the temperature WILL rise on a non-TC mod. The more power hungry your coil, the better your wicking needs to be. Silica is a bad choice for wicking, if you have the option, do select something else.
- Select a lower boiling point juice if you have a "variable" (VV or VW) mod.
- What a lower boiling point juice allows you to do is "lower your settings" to achieve a similarly satisfying hit, which will result in lower temperatures. Lower point liquids include those with lower VG content, or if high VG then diluted with 5-10% of distilled water.
- If using a top coil tank, take a few extra precautions
- Refill when tank is no more than half empty.
- ALWAYS do a swirl to ensure that the exposed wick is fully saturated before every hit.
- Take shorter, even if more frequent, hits.
- The longer the hit the higher the temperature gets, this has been proven via accurate instrumentation.
Using these "Best Practices" will greatly reduce the probability of venturing into the questionable higher temperature ranges.

Mike, somehow I think you're trying to unscrew the inscrutable. After dealing with vapers, family members, who haven't got a clue and running them through all the standard stuff, like battery safety and proper usage, and getting that glassy eyed stare I don't know how this would go over in spite of being straightforward and in plain language with citations.
I know, but at least I can say I tried. It will also give me "links" I can point people to when they do become honestly interested.
I have a more few irons in the fire as well, I "may" have some more "hard scientific" data to post soon. No clue what it says, but I trust the sources.

Done.....Looking good, but the really light yellow color you chose hurts my eyes. Could that be changed for the final draft?
Several challenges here:
- To truly understand vaping is a very complex thing.
- Unless you are a billion dollar corporation you dont have the resources to tackle the task "well".
- I "estimate" that a very high percentage of the early adopters of ecigs had some level of geek in them, you kind of had to if you wanted to succeed. Now that vaping has reached the "commodity" level, you have folks who could care less how it works, they just dont want to smoke. Unfortunately, the level of our technology does not meet that expectation yet (for the most part). These are the users we must "educate", for them to not only be successful, but to also be as safe as possible while doing so.
- While I fully believe the multi-billion dollar guys know most of the really important stuff, they arent sharing it. Therefor all we get is bits and pieces of data, often funded with an agenda in mind.
More like the guy in the tuxedo, up to his armpits in mud and alligators, trying to remember why he was trying to drain the swamp in the first place.
You're right in that it helps to be a geek type or have some technical knowledge regarding electronics, fluids, air flow, chemistry and physiology (pick as many as you want) and that while vaping has come a long way since the Fluval days there's still a long way to go. I count myself, and everyone else here that has discovered and adopted vaping, as being very lucky and as more knowledge comes out it will only get better. Unless and until a complete "system" comes along at a reasonable price, it's going to remain in the hands of the "vape geeks" to refine and discover.
It is kind of funny, but I really suspect that BT has been watching everything on all the forums and is developing new products based on what they learn from us "geeks". Kind of frosts my cookies to think that though.

Is it worth asking the Mods to put this in a sticky?

Thanks to @englishmick I now have some Protank stuff to test.........
And yes Englishmick, I "think" I can do it.....
And yes Englishmick, I "think" I can do it.....
I am cross posting this here since it is testing these tiny azz coils that is driving me too this:
OK, I admit it, I am getting old, or at least my eyes say so.
I am looking for some design similar to below but with a 5x magnifications at a focal distance of 12".
A casual search of Amazon only turn up junk.
Can anyone point me in a direction where I can find a proper pair? Or any other adequate design, they dont have to be inexpensive, but they do need to be good quality.,
These are junk, and inadequate., or at least the pair I have is.
Many thanks for those for offer suggestions.

Smart but ruthless tactic though. Steal all the innovation and ideas out there in the public domain that hasn't been patented yet and then put your own patent on it.
