Nicotine shots and DIY confusion with ratios.

[charlie1465]

Exactly - and it changes the PG/VG ratio too. This is why for DIY from scratch, even with simple ratios, I use a calculator to check.

One tip to prevent accidents with nic concentration: calculate the TOTAL NIC and divide by the TOTAL VOLUME to see what your strength will be.

For example, if I add 6 mls of 100mg nic to 80mls of VG and 10 mls of flavor, what do I have?

6mls at 100 ml/mg = 600 total mg of Nic.
6 mls + 80 mls + 10 mls = 96 mls total.
So my strength is 600/96 = 6.25 mg/ml​

To hit 6 exactly, it's quick and easy using a calculator!!

Thanks this is a good quick safety check. You do hear about people who ended up vaping too much nic.....you need to be pretty serious when your dealing with 100mg/ml.
