Increasing Nic in Nic juice...?

So when I first started to vape, I bought nic juice in the same mg strength as my stinkies used to be - quite a bit of juice.
And as many do I soon found i needed higher nic, so the really low nic has just sat there until now... (cant sell it, hate to chuck it out)

So seeing as i have a bunch of 100mg Nic sitting here I was thinking I can add to the juice...

Questions:
Can I? or is there a reason this is a bad idea?
And Steeping - will it need to steep again?

Thanks!

 

1. Yes, and
2. No (just slightly weaker flavour)
3. Probably not.

Formula:

 

I'm asking the same question in another thread.
I need someone to tell me how much to add, I can't work it out for myself.

 

Well I was thinking for a 30ml bottle starting @ say 3mg.

So 1 ml of 100mg Nic added to 10 Ml of juice would result in something a tad under 13mg
So 3 ml of 100mg in a 30ml bottle of would end up at ~13mg(ish)
4.5ml added would be around ~18mg(ish)
or 3.75ml would be around 15.5mg(ish) which is the ball park i am looking for.

So in your example of 9 to 18mg....
1ml of 100mg Nic to every 10ml of juice (so 12 ml) would give you a hair under 19mg and a bottle of 132mls.....

I think.
(Using my head on this - prone to failure!)

Is that close enough?

 

Hi Skoville have a look at the answer I gave disley here http://forums.canukvapers.com/e-cig...-needed-adjust-nic-strength-2.html#post615619. Download ejuiceme up drop down tools and have a play with the figures, assuming 50/50 30ml bottle @3MG to 18mg would be 5.5ml of your nic and you would end up with 35.5ml of juice at 18.03mg. Hope this helps.

 

This is gt's formula looked at in what seems a logical way to me. It will probably makes people's eyes glaze over, but I'll press 'Post' anyway

Assume you start off with 30ml @ 3mg/ml and you're aiming at 16mg/ml. You want to add X ml of nic @ 100mg/ml to end up with (30 + X)ml @ 16mg/ml.

(30ml @ 3mg/ml) + (Xml @ 100mg/ml) = (30 + X)ml @ 16mg/ml

(30 * 3) + (X *100) = (30 + X) * 16
90 + 100X = (30 * 16) + (16 * X)
90 + 100X = 480 + 16X
100X - 16X = 480 - 90
84X = 390
X = 390 / 84
X = 4.64 ml of 100mg/ml nic to be added

You can double-check the calculations using the 'combine nic' option in eJuiceMeUp or:

30ml @ 3mg/ml contains 30 * 3 = 90 mg of nicotine
4.64ml @ 100mg/ml contains 4.64 * 100 = 464 mg of nicotine

So, altogether you will have (90 + 464) = 554 mg of nicotine in 34.64ml of liquid. That's 554/34.64 = 15.99 mg per ml

 

That's exactly how I derived the formula

 

Oh lordy, not only did my eyes glaze over my brain had a seizure, completely shut down and now I have a migraine from stupidly trying to understand that :confusion:

No surprises that maths was my absolute worst subject at school :dispirited:

think i'll stick to using ejuice calculators
