How Much Nicotine is in E Liquid?
At Wicked Wizard we quote our nicotine levels in e-liquid as a weight per ml for the best accuracy in the manufacturing process, with bottles commonly coming in levels of 0mg, 3mg, 6mg, 8mg, 18mg or 24mg. This simply tells you the amount of the liquid nicotine there is in a bottle, in relation to the total amount of e-liquid in the bottle.
This means that a bigger bottle of e-liquid will contain more nicotine overall than a smaller bottle in the same nicotine strength. So if you get a 15 ml bottle and a 30 ml bottle in the same strength, the 30 ml bottle will contain twice as much nicotine as the 15 ml bottle.
The nicotine is mixed throughout the bottle, though, so whenever you fill up the same tank or clearomizer with e-liquid of a specific strength, you get the same amount of nicotine. In other words, in a bottle of 3mg e-liquid, every ml of e-liquid contains 3mg or 0.003g of liquid nicotine, mixed evenly throughout so you get a consistent hit of nicotine with every puff.
At Wicked Wizard, we stick to weights when quoting the nicotine strength of our e-liquids. However, you might also see nicotine expressed as a percentage. In this case, it tells you the amount of nicotine by total volume in each ml of e-liquid, and 3mg = 0.3%, 6mg = 0.6%, 8mg = 0.8%, 18mg = 1.8% and 24mg = 2.4%.
