Stocking up nicotine.... how much to get ?

[Postmodern Smoking]

From 20th November 2016, you will only be able to buy existing stock of non-TPD compliant products in the supply chain. i.e. larger than 10ml and stronger than 20mg/ml nicotine strength. When stock runs out, or the 20th May 2017 is reached, only TPD compliant (and registered) products can be sold (maximum bottle size 10ml, maximum strength 20mg/ml).

Following on from a partial hijacking of allaboute-cigarettes.proboards.com/threads/recent/65698 shopping thread.
If you want to check approximately how long your TPD-proofing stash of nicotine base will last, or if you are deciding to start/top up one (do so soon!):

Post how much e-liquid that you use (per week, or per day, etc.) and the strength that you vape.... I/some other helpful person, then can let you know how long a litre (or the amount that you specify) will last you..... (I've made a wee spreadsheet!).

I find it easier to work out in mg, my mg/ml has varied over the years but my mg intake has been fairly stable at 90 mg a day over the 3 years I have been keeping detailed records. 1 litre of 72 mg/ml nic is 7,200 mg or 7.2 g.

The calculations will still be approximately valid if for example someone reduces their e-liquid strength but increases their consumption, i.e. roughly maintains their overall mg nicotine intake.



[ETA] - From the other thread, some people appear that they would like confirmation/reassurance that their calculations are correct, and have an idea of how long their stash will last.

Thanks Postmodern Smoking
I think this is useful and have ordered more!

No, using mg takes that out of it completely.  EG in 2013 I was vaping both 20 mg and 6 mg in different devices, in 2014 I vaped 10 mg to reduce the ml I vaped, then went down to 8 mg on Sept 15 ... , currently at 5 mg.  My spread sheet works out the mg, it is all dated and now covers 1067 days so I can see that while my ml use has varied my mg use has not varied nearly as much.

Thanks Dave; I recon I use about 8ml a day at 10mg and say 10% flavouring (actually that is the total of my and a mate I mix for consumption) I have 4l of 72mg in the freezer.
I have come up with about 9 years assuming no drunken spillage; but that still sounds a tad optimistic to me.
(Actually me living another 9 years may be optimistic for all I know)

If you are roughly maintaining your overall nicotine consumption (mg), then if you have reduced your eliquid strength (mg/ml) you must have increased consumption of e-liquid (ml).

I agree that I could easily show or calculate based on daily mg consumption, but feel that most people are more likely to know what strength that they currently vape and approximately how much volume they consume in a give period.
In TJ 's case, who vapes different strengths and amounts day/evening, yes, I did have to do extra calculations to work in the simple spreadsheet, but the aim of the thread is to assist giving people a rough idea of how long a given volume of nicbase would theoretically last, before it is no longer available.

4L of 72 mg/ml should last 9.9 years if consuming 8ml/day @ 10mg/ml nic strength .... assuming no drunken spillages!!!

Very nice offer Dave so if you cold let me know how much I would need to last me 5 years. I use 15ml of juice a day at 12ml nic.
Much appreciated.

5L of 72mg/ml nicbase should last you 5.5 years if consuming 15ml/day @12mg/ml nic e-liquid

(4.5L of 72mg/ml nicbase should last you 4.9 years if consuming 15ml/day @12mg/ml nic e-liquid)

Hi Dave! I'm posting this here rather than the Darkstar Nic thread. Hope you don't mind.
I get through up to 15ml a Day at 15mg (I sometimes get through less, but I'm trying to be realistic, and my RTA's leak occasionally). 500ml @ 15mg has lasted me all Summer and most of the Spring.
I'm well into my last 100ml Bottle so am ready to stock up.
If you do the Calculation then I can see what figures I should get if I use my shonky maths memory!

I started this thread after there appeared to be quite a lot of interest from various members on the shopping thread, so yes, you're posting in the right place

1 litre of 72mg/ml nicbase should last you approximately 10.5 months if using 15ml/day @ 15mg/ml nic strength. 

( 6L of 72mg/ml nicbase should last you approximately 5.3 years if using 15ml/day @ 15mg/ml nic strength )

Whats the life on the liquid when frozen?
VG and PG 72mg

Seen mention of four years on the net along with mention of the liquid degrading

As far as I'm aware it's all largely anecdotal Lee . There will be a slight degradation of nic strength, but if I recall, it's not a huge percentage reduction. Keeping in a freezer will slow down and reduce this.
My previous comments re. VG nic are based on it likely also containing some water and being more aromatic (even freshly made) to that of PG nicotine. Perpetua has used some pretty old nicotine base if I recall correctly.

Personally I'm planning on storing about 6 years worth.


[ETA] - Kurt, a chemist on ECF thinks that VG nic, which becomes more viscous at low temperatures than PG may store better; although I'm still to be convinced!

I have indeed Dave . . . . the oldest of my stash ( all VG based ) is almost 6 years aged now, decanted into amber glass and ' frozen ' immediately on receipt, it appears to be as fresh as the day it went into storage.

There's certainly no degrading of colour or smell - the strength I couldn't tell not being able to test it, I can only say I have no cravings using it. If it has lessened in strength, I'd doubt that's significantly and suspect most of us could handle a slight drop without really noticing it.
