How much nicotine is in a vape?
Most disposable vapes contain 5% nicotine, which is 50 mg/mL, in nicotine-salt form. Some come in lower strengths like 3% (30 mg/mL) or 2% (20 mg/mL), and a few are 0% (zero nicotine). The exact strength is printed on every package.
% vs mg/mL — what the numbers mean
Nicotine strength is shown two ways. The percentage is nicotine by weight; mg/mL is milligrams of nicotine per millilitre of e-liquid. They line up directly:
| Strength | mg/mL | Feel |
|---|---|---|
| 0% | 0 mg/mL | Zero nicotine |
| 2% | 20 mg/mL | Lighter throat hit |
| 3% | 30 mg/mL | Medium |
| 5% | 50 mg/mL | Strongest, most common |
What is nicotine salt?
Almost all disposables use nicotine salt (salt nic) rather than freebase nicotine. Salt nic is smoother at high strengths, so a 5% salt-nic vape feels less harsh than 5% freebase would. That smoothness is why disposables can carry 50 mg/mL comfortably.
Which strength should you pick?
- 5% (50 mg) — the default for most adult vapers and former heavy smokers.
- 2–3% (20–30 mg) — a lighter hit; good if 5% feels too strong.
- 0% (zero nicotine) — flavor without nicotine. Shop zero-nicotine vapes →
Nicotine is an addictive chemical. These products are for adults 21+ who already use nicotine.
Does a higher puff count mean more nicotine per puff?
No. Nicotine strength is a concentration — milligrams per millilitre of e-liquid — so a 5% device delivers roughly the same nicotine per puff whether it is rated 7,500 puffs or 50,000. What changes with capacity is the total e-liquid on board: a bigger device simply lasts longer at the same strength. If you want less nicotine per puff, change the strength (2–3% or 0%), not the puff count.
How to read the label
- "5%" or "50 mg/mL" — the same thing written two ways: nicotine concentration in the e-liquid.
- "Nicotine salt" / "nic salt" — the form of nicotine used in nearly all disposables; smoother at high strengths than freebase.
- Puff count (e.g. 25,000) — capacity, not strength. It tells you how long the device lasts, not how strong each puff is.
- The federal warning box — required on every package: "This product contains nicotine. Nicotine is an addictive chemical."
Is a vape "equal to" a number of cigarettes?
There is no honest one-to-one conversion, and you should be skeptical of any chart that claims one. Cigarettes deliver nicotine in a fixed dose per cigarette; a vape delivers it per puff, and puff length, frequency and device strength all change the total. The only reliable guidance: the strength printed on the label tells you the concentration, and how much you draw determines the dose. Adults switching from smoking typically start at 5% and step down if it feels too strong.
