My quick story. Wasn't a smoker however I chewed tobacco(still a nic addict). Both my first 2 orders from Canadian internet retailers were in my opinion a little lack in a nicotine level. Even after vaping continuously(switching 510 batteries every 30 mins), I would still have to grab for a chew to satisfy my body's craving? Both suppliers assured me that they had sent 24mg nic juice in their orders. Well, last weekend i was happy to be directed to another Canadian supplier that offers 36mg nicotine flavours. So I bought a few plus a couple 24mg cause I liked the sounds of the flavouring. Just received my order today and within 5 minutes of vaping a 36g nic flavour I was sick on the floor. Bad headrush. Nicotine overload. Later, switching to one of my 2 24mg bottles, I handled it a little better but Im actually thinking I might be more a 18mg vaper?? My question is can I dilute these already made bottles of ejuice to a level I will be able to handle? They are a 70/30 split and I have found on the net one of those ejuice calculators???
