How Much Nicotine Do I Need

E-Liquid vs Cigarette Nicotine Content

One of the most common questions about an electric cig relates to which e-liquid nicotine strength is equivalent to a particular kind of cigarette that a person smokes. To better answer this question, it is better to understand how much nicotine is contained in the E-Liquid you are inhaling.

The density of nicotine inside E-Liquid as the following:

- Non nicotine: 0% or 0 mg/ml nicotine, which equivalents to No Nicotine.
- Low density: 0.6% or 6 mg/ml nicotine, which equivalents to Ultra Light Strength Cigarettes.
- Medium density: 1.2% or 12 mg/ml nicotine, which equivalents to Light Strength Cigarettes.
- High density: 1.8% or 18 mg/ml nicotine, which equivalents to Medium Strength Cigarettes.
- XHigh density: 2.4% or 24 mg/ml nicotine, which equivalents to Regular/Strong Cigarettes.
- XXHigh density: 3.0% or 30 mg/ml nicotine, which equivalents to Very Strong Cigarettes.


The nicotine density recorded for e-liquid pertains to the amount of nicotine in milligrams for each milliliter in the e-juice.

That means a 10ml bottle of 24mg nicotine e-liquid would have 240mg of nicotine in it (24mg x 10ml). Additionally, a 50ml bottle of e-liquid with 24mg would have 1200mg of nicotine in it (24mg x 50ml).

Different brands of cigarettes vary in terms of their nicotine content. Normally nicotine constitutes approximately 0.6-3.0% of dry weight of tobacco in a cigarette. Obviously a longer 100ml cigarette has more nicotine in it than a standard or king size 84ml cigarette. For the most part, though, here is, for example, the amount of nicotine that is in a typical 84ml tobacco cigarette:

If you smoke Regular cigarettes, like a Marlboro Red, for example, the nicotine content in every cigarette has relatively 1.2mg, meaning each pack has 24mg total of nicotine (1.2mg multiplied by 20 cigarettes).

If you smoke Light cigarettes, like a Marlboro Light, for example, the nicotine content in every cigarette has relatively 0.7mg, meaning each pack has 14mg total of nicotine (0.7mg multiplied by 20 cigarettes).

If you smoke Ultra Light cigarettes, like a Marlboro Ultra Light, for example, the nicotine content in every cigarette has relatively 0.5mg, meaning each pack has 10mg total of nicotine (0.5mg multiplied by 20 cigarettes).

When you refill your e-cartridges with e-liquid, you may need to know how much nicotine is contained in your refilling e-liquid. There are approximately 20 drops of e-liquid per milliliter. So, using our 24mg nicotine e-liquid once again as an example, there would be 1.2mg of nicotine per drop (24mg/20 drops). So, if you put three drops of e-liquid onto a e-cartridge (or directly onto the atomizer for those of you that direct-drip), that means you will take in 3.6mg of nicotine from the time you start vaping until you top off again.


The amount as well as the feeling of the nicotine the body absorbs from electronic cigarette smoking depends on many factors, including the density of the nicotine in e-liquid, the vaping quantity, the smoking frequency and timing, and the smoking inhaling respiration.

Actually the nicotine in the E-Liquid can not be absorbed completely by the smoker. For example, if you intake 1 ml of E-Liquid which contains 24 mg of nicotine, you will not necessarily absorb all 24 mg of the nicotine. You might only absorb about 50-80% of the nicotine according to your personal smoking habit.


It should be noted that, although it is highly addictive, no studies have shown nicotine to be a carcinogen. It is simply the fix that cigarette smokers crave. It is recommended that those who have a demonstrated sensitivity to nicotine, are pregnant or breastfeeding or who have unstable heart conditions, should discuss the use of any E-Liquid with a doctor before using.
