If my math is correct, if you took an empty bottle, filled halfway with 12mg/ml and the other half with 3mg/ml, you should have somewhere around 7.5mg/ml.

You can mix the two, but the strength will be between the minimum (3mg) and the maximum (12mg). The nicotine strength in eliquid is measured as milligrams of nicotine per milliliter of liquid (mg/ml). So if you took 1ml of 3mg and 12mg each, then you would have 15mg in that 2ml, so it would be 7.5mg/ml in the end.

If you wanted stronger, you would have to mix in more of the hazelnut flavored one that you're not fond of. If you want the liquid to taste better to you, the nicotine strength will be less.

If the 12mg seems to be the proper strength for you, then your best bet is to search for that eliquid online in your preferred flavor and strength. Otherwise, if you don't need the full 12mg, you may be able to find the proper balance between the two that you have between strength and taste.

Hi. It can never be higher than 12mg if your adding something that is less than 12mg. By doing that, you are diluting the 12mg and thus lowering it. Hope that helps.

I can tell you this I was a pretty heavy smoker of almost 2 packs a day of Newport 100's and I was easily able to quit with 6mg nicotine without a problem.

When I first started vaping when I was a dual user I use to get 18mg Nic juice and it was horrible because it was so harse as a direct lung inhale that I didnt enjoy it... So it wasnt until I bought my first bottle of 6mg that I was yes ok this is much better and flavor is much better then next bottle I went cold Turkey off the ciggs and haven't had one in almost 6 years.

The thing about stem nic is 3mg and 6mg is plenty for anyone because it's about how much you intake because it builds up in your system unlike salt nic where it's a little more along the lines of a cigarette and gives instant satisfaction but when I quit salt nic wasnt a thing but I've tried it and man I'm glad I direct lung because most of that salt nic is flavorless.

I mix a 6- mg and a 12 mg to get 9 mg

Can the shop not just add straight nic to the bottles?

I’ve decided to mix the two in the tank to give it a try. Isn’t half bad actually.

If you find you're having this issue often (finding flavors you like, but not in nicotine strengths you want), you can always get a bottle of just nicotine and increase it yourself.

To increase a 30mL bottle at 3mg/mL to ~12mg/mL would only take an additional 3mL of 100mg/mL nicotine. It would slightly dilute the flavor, but you can have exactly the flavors you want and you can pick up a 120mL bottle of 100mg/mL nicotine salts for about $15.

You should consider mixing your own flavors. We can always recommend some stuff to try.

What nic level do you vape? Are they both 70/30?
