How Many Puffs a Day Is Normal When Vaping?
There's no single "normal" number of puffs per day. Studies have found very different averages depending on who was measured and how. And importantly, those numbers describe typical use, not a safe limit.
The numbers below show how much puff counts can vary, and why puff count alone is a poor measure of nicotine use.
How many puffs do people take, according to studies?
| Study | Who was measured | Puffs per day |
|---|---|---|
| PATH Wave 7, U.S. ages 12–30 (2026) | Anyone who vaped in the past month, N=2,606 | Mean 66.9 puffs/day |
| Circadian topography study | 24 adult e-cigarette users over 24 hours | Mean 156.2 (range 44–345) |
| Maryland daily-user survey | Daily exclusive adult users; puff-count data for 50 | Mean 365; median 200 (IQR 90–360) |
Three real studies, three very different numbers. That doesn't mean one of them has to be wrong. They looked at different groups of people and measured their use in different ways.
Why puff count doesn't tell you how much nicotine you're using
A puff isn't a standard unit.
Nicotine concentration can vary a lot between e-liquids, from close to 0 to more than 50 mg/mL (Gholap et al., 2020). How long you inhale and what kind of device you're using can also change how much nicotine one puff represents.
One study of experienced vapers shows the problem pretty clearly. At a 6W power setting, participants took 57 puffs and consumed about 3.5 mg of nicotine during the session. At 10W, they took fewer puffs, 46, but consumed more nicotine, about 4.2 mg (Nicotine & Tobacco Research).
So the same number of puffs doesn't necessarily mean the same amount of nicotine consumed. You can even take fewer puffs while consuming more nicotine from the e-liquid.
Why "140 puffs is normal" is the wrong takeaway
You may have seen the claim that the average vaper takes around 132 to 140 puffs a day. Those numbers do come from a real study.
In 2015, researchers analyzed more than a million puffs recorded by a connected e-cigarette used by 185 people over 6,144 user-days. They found a mean of 163 puffs per user per day and a median of 132. When they excluded days with fewer than five puffs, the median rose to 140 (Dautzenberg & Bricard, 2015).
Both 132 and 140 are real numbers from that dataset. But they're two versions of the median from one study using one connected-device brand, not universal benchmarks. Puff counts also varied widely between users and from day to day.
The researchers weren't saying that 140 puffs was normal or safe. None of the studies above gives us a safe daily puff limit.
Does a lower puff count mean vaping is safe?
Not really. Puff count and health risk aren't the same question. Long-term research on vaping is still developing, especially compared with the decades of research we have on cigarette smoking.
A 2025 systematic review found evidence of more respiratory problems among non-smokers who currently vaped than among non-users, although the strength of the evidence varied across the studies (Kundu et al., 2025).
Nicotine is also a particular concern for teens and young adults because the brain continues developing into the mid-20s. The U.S. Surgeon General has warned that nicotine exposure during adolescence can harm brain development, including areas involved in attention and learning (U.S. Surgeon General, 2016).
None of this gives us a safe number of puffs per day. Current research doesn't give us a number below which vaping can be called risk-free.
A better way to track your own use
Instead of comparing yourself with a study average, track a couple of things in your own use:
How much e-liquid you use and how strong it is. If you multiply the amount of e-liquid you use in a day by its nicotine concentration, you get the amount of nicotine contained in the liquid you used — not the amount your body absorbs, which varies by person and device. But it gives you another way to track your consumption instead of relying only on puff count.
How your own use changes over time. Notice when you first vape, how often you reach for the device, and whether your use is increasing or decreasing. A published average tells you what happened in one group of people. Your own trend tells you what's changing for you.
