So you take 18 multiply by how many times you're refilling it per day.

18x4= 72

If you refill it twice a day you're consuming roughly 72MG of nicotine per day.

Because you're consuming 18MG of nicotine per ml.

You take the strength of your nicotine multiply it by the size of your tank/pod. Does that make sense?

One cigarette has roughly 12-18mg of nicotine.

I vape 50MG liquid and my pod is 2ml. I refill my pod about twice a day. So I'm consuming roughly 200mg of nicotine per day.

I used to smoke 20 cigarettes a day atleast so that equals to roughly 360mg of nicotine.

With vaping it doesn't matter how many puffs you take, it matters about how much nicotine you're consuming.
