Vape vs Cigarette Nicotine: How Strengths Actually Compare
What the mg on the bottle really means
Key Takeaways
- E-liquid strength is nicotine per millilitre: a 20mg/ml pod holds 40mg of nicotine in 2ml.
- A 20mg 2ml pod is commonly compared to a pack of twenty cigarettes in nicotine delivered.
- Absorption differs: vapour delivers nicotine a little more slowly and less completely than smoke.
- Pick strength by habit: 20mg for a pack a day, 10mg for lighter smokers, then step down.
The single most confusing thing about switching is that cigarettes and e-liquids measure nicotine differently. A cigarette is quoted per stick; e-liquid is quoted per millilitre. Neither number tells you what your body absorbs, which depends on how you smoke or vape.
This guide translates between the two honestly, so you can pick a strength that actually replaces your habit.
Translating the Numbers
A typical cigarette contains 10 to 12mg of nicotine, of which a smoker absorbs only 1 to 2mg: combustion wastes most of it. A 2ml pod of 20mg/ml e-liquid contains 40mg of nicotine, delivered gradually across the hundreds of puffs the pod lasts, with absorption per puff lower than smoke.
Net result: the industry’s rough rule that a 20mg 2ml pod does the nicotine work of about a pack of twenty holds up as a starting approximation, not a law. Draw length, frequency and device power all bend the maths.
Strength Picker for Switchers
| Suggested Strength | Why | |
|---|---|---|
| 20+ a day | 20mg nic salt | Fast, full craving relief; anything weaker risks relapse |
| 10 to 20 a day | 10 to 20mg nic salt | Start higher, step down once stable |
| Under 10 a day | 5 to 10mg | Enough to satisfy without overshooting |
| Social smoker | 5mg or 0mg | Ritual replacement more than nicotine need |
