How Much Nicotine Is in a Vape?
Understanding nicotine content across different vaping products and how it compares to cigarettes.
Shop Nic Salts All E-LiquidsQuick answer: It depends on the product. A 10ml bottle at 20mg/ml contains 200mg of nicotine in total. A 600 puff disposable typically delivers around 2mg of nicotine per puff under test conditions. In practice, you absorb a fraction of the stated concentration per session depending on device efficiency and usage patterns.
Nicotine content in vaping products is shown as a concentration (mg per ml) rather than as a total amount, which can make it confusing to compare to cigarettes or to understand how much you are actually consuming. This guide clears it up.
Nicotine Content by Product Type
| Product | Typical strength | Total nicotine in product | Per puff (approx) |
|---|---|---|---|
| 10ml nic salt bottle (20mg) | 20mg/ml | 200mg total | 0.1 to 0.2mg absorbed |
| 10ml freebase bottle (6mg) | 6mg/ml | 60mg total | 0.03 to 0.06mg absorbed |
| 600 puff disposable (20mg) | 20mg/ml in ~2ml liquid | ~40mg total | ~0.07mg absorbed |
| Nicotine-free e-liquid | 0mg/ml | 0mg | 0mg |
| Cigarette (for comparison) | 10 to 14mg per cigarette | ~12mg per cigarette | 1 to 2mg absorbed per cigarette |
Understanding the Concentration vs Absorption Difference
The concentration on a bottle (e.g. 20mg/ml) tells you how much nicotine is in the liquid, not how much enters your bloodstream. The amount absorbed depends on the device, your draw technique, how much liquid you use per session and the form of nicotine (nic salt vs freebase).
Nic salts are absorbed more efficiently and rapidly than freebase nicotine. This is why 20mg nic salt feels satisfying at the same session length where 20mg freebase might not: nic salts deliver more nicotine to the bloodstream per puff.

What Is the Maximum Legal Nicotine Strength in the UK?
Under the Tobacco and Related Products Regulations 2016 (TPD), the maximum nicotine concentration permitted in UK e-liquids is 20mg/ml. Refill containers are limited to 10ml. Tank capacity in devices is limited to 2ml. These limits were set to reduce the risk of acute nicotine toxicity and ensure products are used at safe dosing levels.
Any product sold with a higher concentration in the UK is non-compliant and potentially dangerous. Celtic Vapours only stocks TPD-compliant products.
