Nicotine measurements and cartridge contents

[Kate]

I have a couple of questions about things I've picked up on this forum.

1/ We often say that nicotine potency is measured in mg per ml eg: 16mg juice would mean 16mg of nicotine per 1ml of juice. Can anyone point me in the direction of the source of this information? I have heard that Johnson Creek measures mg per 1.2ml of juice and am wondering if there is an agreed standard or if different manufacturers make it up as they go along.

2/ Another thing we say here is that a classic cartridge holds about 1ml of juice, a mini 0.3-0.5ml and, sorry, I can't remember the amount for a super mini. Can anyone confirm that these measurements have been verified or are they guesses?

Thanks.

all i can say is the original devices cigars followed by the classic held around 1 ml of liquid.. most of the info is based on the amount of liquid bing 1 ml.. it made sense when the carts held 1 ml.. now a lot of it dosnt with carts holding any amount.. the copy and paste has been busy..

when i buy 24 mg liquid i "assume" it to be per 1 ml..

but none of this is written in stone.. plus without the kind of tests jason is doing none of it is provable or disprovable..

we take a lot on trust.. in fact we take it all on trust..

Ok, thanks Trog.

I'd like the mg per ml measurement to be true but was brought down to earth on hearing that JC doesn't measure that way. It seems that their 24mg works out at about 18mg per ml. It hadn't crossed my mind to question this before but I'm wondering if we should be asking suppliers how their nicotine measurements are worked out.

I think I'll measure the amount of eliquid in a classic cartridge myself soon to see how close we are when we advise 1ml. I also have an ecigar cartridge so will check that too. It could be that all brands are different with this too, some might fill more than others.

they are not all equally full kate.. a full classic is near enough 1 ml.. a full cigar is a little bigger at 1.2 ml.. some come with less in thow.. or at best some variance..

we have syringed lots of different sorts.. some yield better results than others.. he he

from an actual usage point of view there is at least 25% wastage as well.. which is why topping up works well.. this gets rid of the wastage.

I managed to squeeze 1ml from a Ruyan ecigar cartridge and 0.8ml from both Janty classic and generic classic cartridges.

Kate on the lab tests on the wicked 18mg juice.

9% content was nicotine, these i feel are the parameters that certainly the authorities will work on..

For Chip testing i feel this figure is the relevant one.. Regardless of MG strength quoted..That really is irrelevant, its nicotine by volume % that appears to be applicable.

Thanks Pillbox, I appreciate the info.

In terms of packaging and compliance with trading standards the percentage might be the appropriate measurement but for users comparing with cigarette habits it's not as useful. Cig nicotine levels are measured in mg so percentages of ml are going to be harder to work out.

If the average esmoker vapes 2ml of 18mg Wicked eliquid a day and 9% is nicotine then we still don't know how much nicotine are we getting compared with approx. 1mg nic per cig?

If the mg measurements are not meaningful we could be deluding ourselves about cutting down or even getting enough. I have a funny feeling that all manufacturers of eliquid use different criteria for measuring and we are way out on calculations of how much we're getting.

well assuming my body is anything to go buy.. lets assume its been used to xxxx amount of nicotine for a great number of years and it knows what it wants to keep it happy....

it wants between two and three ml of so called 24 mg liquid per day.. i am going to ignore my higher thinking and let my body tell me..

i recon 1 ml of 24 mg liquid gives me the equivalent of ten medium to high strengh fags.. perhaps a little less..

i have two other family members who all real smoked roughly the same and now we all e smoke roughly the same..

this isnt carts this is actual liquid use.. carts do not ever deliver up all their contents..

one ml of extra high strengh liquid equals ten fags.. at least that is what our three bodies tell us.. that will do for me..he he

You could well be right Trog but the problem with guessing is that nicotine is one of those drugs we tend to want more and more of to satisfy ourselves. What if you and your sons have built up a tolerance and are actually vaping twice as much nic as you think? I'm not saying you are, I'm just speculating that if the mg measurements are not accurate we have no reliable way of working out what dosage we're getting.

I just hope our dealers are trustworthy enough to try to be accurate with potency measurement claims. Taking anything on trust with esmoking is not easy though, I'd rather know for sure.

The kind of measurement you're talking about, Kate, is used in every other nicotine method I personally use. Snus come in 3mg, 6mg, 8mg and now 15mg levels. Ariva tablets are 2mg; Stonewalls are 4mg. Etc.

Since I know what my cigarettes delivered and how many I smoked, I can pretty well estimate how much nicotine I'm using (and I use less than 1 Janty cart per day; a cart usually lasts me two or more days with high nic liquid).

So while percent of liquid content is important to chemists, it's meaningless to e-smokers.

we are just a bunch of chemical reactions and electrical impulses.. the electrical impulses could be thought of as the mental state and the chemical reactions the physical state..

however i have always wondered exactly which bit is in charge and actually runs things.. he he he
