Switching from cigarettes to vapes often raises one big question: “How many cigarettes does a vape equal?”

The answer depends on three things: nicotine strength, e-liquid volume, and puff style. This guide breaks it down with simple maths, quick charts so you can choose the right vape device and nicotine level without confusion.

Key Takeaways (TL;DR)

• In the UK, disposables and pods must follow TPD rules: max 2 ml e-liquid and max 20 mg/ml (2%) nicotine.
  

• A cigarette contains about 10–12 mg nicotine, but the body only absorbs 1–2 mg.
  

• A 2 ml pod at 20 mg/ml = 40 mg nicotine in the liquid, which works out to 20–40 cigarettes depending on absorption.
  

• A common shortcut: 15 puffs ≈ 1 cigarette → 1 puff ≈ 0.067 of a cigarette.
  
  

The Simple Vape-to-Cigarette Formula

To compare fairly, you only need three numbers:

1. Nicotine strength (mg/ml)
   

2. Tank size (ml)
   

3. Absorbed nicotine per cigarette (1–2 mg on average)
   
   

Step-by-Step

Total nicotine in tank = strength × ml
Cigarette equivalents = (strength × ml) ÷ (1–2 mg absorbed per cig)

Example A: Common UK Disposable/Pod

• 2 ml at 20 mg/ml → 40 mg total
  

• 40 ÷ 2 = ~20 cigs (conservative)
  

• 40 ÷ 1 = ~40 cigs (upper bound)
  
  

Rule of thumb: 2 ml @ 20 mg ≈ 20–40 cigarettes

Example B: Lower Strength

• 2 ml at 10 mg/ml → 20 mg total
  

• 20 ÷ 2 = ~10 cigs
  

• 20 ÷ 1 = ~20 cigs
  
  

Rule of thumb: 2 ml @ 10 mg ≈ 10–20 cigarettes

Puffs vs Cigarettes (Why It Varies)

Nicotine maths isn’t the whole story — puff count also matters.

• A cigarette usually takes ~12–15 puffs.
  

• That’s why people use: 15 puffs ≈ 1 cigarette → 1 puff ≈ 0.067 of a cigarette.
  

• Example: 600-puff disposable ÷ 15 = ~40 cigarettes.
  
  

But results vary with:

• Longer or shorter drags

• Higher or lower wattage

• Coil resistance (MTL vs DTL)
  
  

Treat puff-to-cig ratios as a guide, not exact science.

Picking Nicotine Strength (Start Right, Then Step Down)

To avoid cravings and relapses, match your old smoking habit first:

• Heavy smokers (20+ per day): start at 20 mg (2%) nic salts.
  

• Moderate smokers: 10 mg/ml is usually enough.
  

• Light smokers: 6 mg/ml or below.
  
  

If vaping feels harsh, dizzy, or nauseous → step down.
If you still crave cigarettes → step up within legal limits or change device style.

Example quitting path:
Pack-a-day smoker → 20 mg for 2–4 weeks → 10 mg → 6 mg → 3 mg → 0 mg.

MTL vs DTL (Which Feels More Like Smoking?)

• MTL (Mouth-to-Lung, ≥1.0Ω): tighter draw, smaller clouds, stronger throat hit. Closest to cigarette feel.
  

• DTL (Direct-to-Lung, <1.0Ω): airy draw, big clouds, usually lower nicotine per ml. Less cigarette-like.
  
  

 For a realistic cigarette feel, choose MTL pods with nic salts (10–20 mg/ml).

How Long Does a Disposable Last?

• A 600-puff device lasts most ex-smokers 1–2 days.
  

• ~300 puffs/day = ~2 days for a 600-puff stick.
  

• Heavy users (deep drags, frequent vaping) finish faster; light users stretch it longer.
  
  

DIY Vape-to-Cig Calculator (Copy & Use)

• Total mg = ml × mg/ml
  

• Cigs (range) = total mg ÷ 2 → minimum, total mg ÷ 1 → maximum
  

• Puff shortcut = puffs ÷ 15
  
  

Worked Example

• 2 ml × 20 mg/ml = 40 mg → ~20–40 cigs

• 600 puffs ÷ 15 = ~40 cigs
  
  

Final Thoughts

There’s no single magic number for “how many cigarettes are in a vape.” But you can use nicotine maths for a range (20–40 cigs per 2 ml pod) and the 15 puffs = 1 cigarette shortcut for quick planning.

Start strong enough to keep cravings away, use MTL if you want a cigarette-like feel, and step down calmly until you reach 0 mg.

FAQs 

Is 2% (20 mg/ml) a lot?

Yes  it’s the UK maximum. Heavy smokers switching usually start here. If it feels harsh, step down.

Which vape feels closest to a cigarette?

An MTL pod with nic salts (10–20 mg/ml) and a tight airflow.

Is vaping bad for lungs?

Not risk-free — but much less harmful than smoking. Aim to taper nicotine over time.

How many puffs per day are OK?

There’s no “safe” number. Stick to the lowest strength and fewest puffs that keep you smoke-free. Then reduce gradually.
