Question about Nic concentration

[jimrug1]

I recently ordered 30ml of an e-liquid and requested 18mg of Nicotine. When I received the bottle, it was labeled 1.8% Nicotine. I am still foggy on how the concentrations are figured. I always thought "mg" is a weight measure and "ml" was volume. So question #1. How many mgs in one ml? Doesn't that vary depending on the weight of each? And question #2. What is the math behind 1.8% Nicotine in 30 ml ending up as 18mg/ml?

One of the reasons I am curious is that this juice seems stronger than my other 18mg juices. Another reason is I would like to eventually DIY my own juices but am really confused about the math of mixing everything. Thanks in advance for any explanation/ advice.

Jim,

Your confusion is very understandable. Grams (or milligrams) are indeed a measure of weight, and liters (or milliliters) are a measure of volume. I'm not an expert authority here, so I might be wrong, but it has always seemed to me that the nicotine percentage designation (1.8% in your example) was something of a misnomer. The correct measure is mg/ml, in much the same way that blood glucose is measured in mg/dl, as weight per a given volume. The only math I'm aware of in translating the ersatz percentage figure into mg/ml is multiplying by 10.

Different formulations of liquid nicotine provide different impacts/effects. I think that's based largely on "purity." I'm not sure what impurities mean in liquid nic---something in the extraction filtering process perhaps---but lack of purity decreases impact. A liquid nic that is 99+% "pure" will have more nicotine effect---throat hit, brightness, stimulation buzz---than one that is only 98% pure. It's a question of who made a given liquid nic and how they did so.

There's a wonderful (and huge) thread about liquid nicotine somewhere in the forums that almost surely answers your question. I'd link it for you, but I don't have time right now to search for it.

As Bill said, there is a thread somewhere that breaks this down. After speaking with a friend of mine today we talked about the very same questions. In particular, I wondered, too, how the percentage broke down in terms of "puffs" or whatever. It doesn't really matter to me, but it would be nice to know.

Thanks to Bill and Mr Mann for your comments. I am still confused but I will do some searching and see if I can find the thread you are referring too...
