How much nicotine is in a cigarette vs a vape?

“How many cigarettes is my vape?” sounds like a simple question, but it has two different answers depending on whether you mean the nicotine in the product or the nicotine that reaches your body. This guide shows both, with the maths, so you can see where the popular comparisons come from.

Nicotine in a cigarette: what’s in it vs what you absorb

A cigarette’s tobacco contains roughly 8 to 15mg of nicotine. A smoker absorbs far less of it: about 1mg per cigarette on average.

What’s in it. The UK Committee on Toxicity gives an average of 8 to 9mg of nicotine for a cigarette, and 10 to 15mg for a conventional cigarette (Committee on Toxicity). Our calculator uses 10mg, a round figure within that range.

What you absorb. Most of that nicotine never reaches the smoker’s bloodstream. A study of daily smokers measured an average intake of 1.04mg per cigarette (Benowitz and Jacob, 1984). The US National Cancer Institute reports about 1mg, with a range of 0.37 to 1.60mg (NCI), and the Committee on Toxicity gives a typical figure of around 1mg, ranging from about 0.3 to 3.2mg.

So when you see a cigarette described as “10mg” in one place and “1mg” in another, both can be right. One is the nicotine in the tobacco, the other is what a smoker takes in.

Nicotine in a vape: the formula

The nicotine in a vape is the amount of liquid multiplied by its strength. Divide by how many days it lasts you to get nicotine per day.

The formulas our nicotine calculator uses:

• Strength in mg/ml. If your label shows a percentage, multiply by 10. So 5% is 50mg/ml.
• Nicotine per device = liquid (ml) × strength (mg/ml).
• Nicotine per day = nicotine per device ÷ the days one device lasts you.
• Cigarette comparison = nicotine per day ÷ 10, using 10mg per cigarette.

Each result is rounded to a whole number. The full method, including rounding and the % conversion, is on our methodology page.

Example 1: 2ml at 20mg/ml, lasting 2 days. That’s 2 × 20 = 40mg per device. Over 2 days, it’s 20mg a day, about the nicotine content of 2 cigarettes.

Example 2: 20ml at 5%, lasting 4 days. 5% is 50mg/ml, so that’s 20 × 50 = 1,000mg per device. Over 4 days, it’s 250mg a day, about the nicotine content of 25 cigarettes, or about 1.3 packs of 20.

These are comparisons of nicotine content, not of what you absorb, and they’re estimates. How much nicotine you absorb from a vape varies a lot. It depends on the liquid’s strength, your device and how you puff: longer puffs deliver more nicotine (Blank and others, 2020), and delivery varies widely between people, even on the same device (Spindle and others, 2015; Yingst and others, 2019).

Labels aren’t always accurate either, and percentages can be measured by weight or by volume, which gives slightly different numbers (Jackler and Ramamurthi, 2019). We take the figure you enter as correct.

Does one pod equal one pack?

Not by nicotine content. A typical 0.7ml pod at 59mg/ml holds about 41mg of nicotine, an estimated 4 cigarettes’ worth of nicotine content (how we calculate this), while a pack of 20 holds about 200mg in its tobacco.

The “one pod equals one pack” line is widely repeated. We couldn’t trace it to an official health source, so here’s how the numbers line up:

Comparison	Pod (0.7ml at 59mg/ml)	Pack of 20 cigarettes
Nicotine in the product	about 41mg	about 200mg (20 × 10mg)
Nicotine a smoker absorbs	varies, not estimated	about 20mg (20 × about 1mg)

Compare content with content, and a pod holds about a fifth of a pack’s nicotine. Compare the pod’s content with what a smoker absorbs from a pack, and the pod holds about twice as much. The “one pack” idea sits somewhere between the two. One possible reason is that it mixes two different measures.

What a pod actually delivers depends on how you use it. In one small study, six regular users of a pod device with 59mg/ml liquid took about 30 puffs over 10 minutes. The researchers described the rise in their blood nicotine as similar to studies of smoking one cigarette (Yingst and others, JAMA Network Open, 2019). The same study notes that the 59mg/ml figure came from the manufacturer and wasn’t measured. How many sessions like that you get from a pod depends on you, which is why our calculator compares nicotine content only.

How many cigarettes are in a pack?

In all six markets we checked, the law sets 20 cigarettes as the minimum pack size. In Australia, 20 is now the only size allowed, and New Zealand also allows packs of 25.

Market	Rule	Source
United States	At least 20 cigarettes	21 CFR 1140.16(b)
United Kingdom	At least 20 cigarettes	Standardised Packaging of Tobacco Products Regulations 2015, reg 4(8)
Ireland	At least 20 cigarettes	Public Health (Tobacco) Act 2002, s.38
Canada	At least 20 cigarettes	Tobacco and Vaping Products Act, s.10
Australia	Exactly 20 cigarettes, in full effect from 1 July 2025	Public Health (Tobacco and Other Products) Regulations 2024, s.45; Department of Health
New Zealand	20 or 25 cigarettes only	Smokefree Environments and Regulated Products Regulations 2021, reg 46; Ministry of Health

These are the legal rules, checked on 9 October 2026. They don’t tell you which sizes are most common in shops. Our calculator counts packs of 20, so if you buy packs of 25 in New Zealand, your packs a day will be a little lower than the calculator shows.
