My local vape shop is a member of AEMSA. All their juice is manufactured to AEMSA standards, which gives me confidence I'm vaping quality stuff. They shared this with me today and I thought you might find it interesting. This was sent to the White House by AEMSA in response to the Deeming Regulations:

For start, the authors did not find formaldehyde but formaldehyde hemiacetals. This is a combination of formaldehyde and alcohols (formaldehyde-propylene glycol or formaldehyde-glycerol). The authors characterized them as formaldehyde-releasing agents, providing a reference to a study evaluating contact dermatitis from such agents. However, looking at the study referenced, it is clear that those formaldehyde-releasing agents have nothing to do with formaldehyde hemiacetals found in e-cigarette aerosol. Moreover, there is absolutely no evidence that hemiacetals are toxic or carcinogenic. In fact, it is possible that the formation of hemiacetals might protect against damage induced by formaldehyde. Nevertheless, the authors considered the risk equal to formaldehyde and calculated the risk of cancer. There are many other major issues in that study. The authors fail to realize that voltage levels provide no information about the thermal load of an ecigarette device. It seems that both the researchers and the reviewers who approved the study for publication missed that energy should be expressed in watts. As a result, we do not know how many watts were applied to the atomizer. However, there is a way to approximate this, through the information provided about liquid consumption per puff. The authors report that 5mg of liquid were consumed at 3.3 volts. Based on measurements I have performed, such consumption is observed at about 6-7 watts at 4-second puffs. Thus, the atomizer resistance is probably 1.6-1.8 Ohms. This means that at 5 volts the energy was around 14-16 watts. That would be an extremely high value for most commercially-available atomizers (excluding some rebuildables which can withstand such high wattage levels). Thus, it is more than obvious that once again the atomizer was overheated, which of course will result in very high levels of formaldehyde production. What the authors ignore is that these conditions, commonly called dry-puff phenomenon (which is explained in detail in one of my published studies), are easily detected by the vapers. In fact, overheating results in an unpleasant taste that none can withstand. As a result, no vaper is ever using the e-cigarette at such conditions and, thus, will never be exposed to such levels of formaldehyde. The story published in New England Journal of Medicine is similar to finding carcinogens in an overcooked piece of meat that none can ever eat. Of course the findings are true, but none will be exposed to the levels found.

Thanks for posting this, RB! My local B&M is also a member of AEMSA.
Mine is a member of the MAFIA.
Good analysis!
And part of it is exactly what I read in my first scan of the test - the conditions were absurd, effectively proving that "dry hits are bad" and that if you crank up the voltage to a level that chars the juice and might actually BURN your wick, you probably do not want to inhale that.

not sold on AEMSA myself
Why not Willy? Today is the first time I've heard of them.
sorry Ping, can't really get into it ... don't want to derail this thread.
for now, let's just say ... I'm not sold on AEMSA.
I see membership is still $758+ per month
I'd be interested to know as well. From what I've read and learned from my Vape Shop, they're working very hard to protect our rights.

Willy, I don't believe they are catering to the individual vaper, like us. They are catering to the Vape Shops/Juice Makers, who make and sell juice. I'm grateful my Vape Shop is a member and makes juice to their high standards. Yes I am.
Anyone got a shot of a Radius side by side with a P3 in 18350 mode? Curious how they line up in terms of height and overall size. Even better if they're both topped with A kabuki

Seems it has already been derailed. It use to be a Radius Thread!sorry Ping, can't really get into it ... don't want to derail this thread.

Don't we already have a section on the Forum for this topic?
Particularly given its importance.
Respectfully; Knife
