“Zeroing a vape” refers to inhaling vapor in a way that results in no visible exhale. It’s also known as stealth vaping, the zero method, or ghost inhaling. This technique is popular among users who want to vape discreetly by minimizing or eliminating visible vapor clouds.
While the method is widely discussed online, it’s important to understand how it works, why it works, and how to practice it safely. This guide covers everything you need to know, including step-by-step instructions, tips for reducing vapor production, mistakes to avoid, and safety considerations from health authorities like the CDC and FDA.
What Does “Zeroing a Vape” Mean?
Zeroing a vape is a technique where you:
- Take a small puff
- Hold the vapor inside your mouth
- Take a second inhale of fresh air
- Hold it in your lungs for several seconds
- Exhale with little or no visible cloud
The goal is to make the vapor condense inside the lungs, reducing visibility during exhale.
Zeroing is not a “trick”—it is simply a controlled inhale-exhale method that limits visible vapor output.
How Zeroing Works: The Science Behind It
Vapor disappears because of two main factors:
1. Condensation in the Lungs
When vapor enters the lungs, the warmth and humidity help condense and disperse the particles, making the cloud less visible.
2. Dilution With Fresh Air
Taking a second inhale reduces vapor density, which directly reduces cloud size.
3. PG/VG Ratio Influences Cloud Production
- VG (Vegetable Glycerin): Produces large, thick clouds
- PG (Propylene Glycol): Produces smaller, thinner clouds
A higher PG ratio makes zeroing much easier.
How to Zero a Vape (Step-by-Step Tutorial)
This is the classic zero method—easy to learn and works with disposables, pod systems, and low-wattage devices.
Step 1 — Take a Small, Controlled Puff
Start with a small amount of vapor. Big hits create too much cloud, making zeroing difficult.
Tips:
- Draw gently
- Avoid deep lung inhales
- Keep puff length to 1 second or less
Step 2 — Hold the Vapor in Your Mouth
Pause for 1–2 seconds before inhaling into your lungs.
This helps the vapor cool slightly, making the next step more effective.
Step 3 — Take a Sharp Second Inhale of Fresh Air
This is the key part of zeroing.
Inhale a breath of pure air immediately after the first puff. This dilutes the vapor and reduces cloud density.
Step 4 — Hold for 3–5 Seconds
This allows vapor to condense and break down.
Longer hold = less visible exhale.
Step 5 — Exhale Slowly Through Your Nose or Shirt
- Slow exhale = almost invisible
- Nose exhale = finer particles
- Shirt exhale = hides remaining vapor
If done correctly, there will be little to no visible cloud.
Tips to Make Zeroing Easier
✔ 1. Use Higher PG E-Liquids
50/50 or high-PG juices produce less vapor → easier zeroing.
✔ 2. Lower the Device Wattage
Lower heat → smaller clouds.
For disposables, take smaller puffs.
✔ 3. Partially Close Airflow
Restricted airflow reduces vapor production.
✔ 4. Use Low-Vapor Devices
Pod systems and disposables are ideal for stealth vaping.
✔ 5. Take Mini Puffs Instead of Long Hits
Smaller amounts of vapor are far easier to zero.
✔ 6. Practice the Second-Inhale Technique
Most beginners skip this step—it’s the secret to zeroing correctly.
Common Mistakes When Zeroing a Vape
❌ Taking Huge Lung Hits
Large vapor volume = impossible to hide.
❌ Using High-VG E-Liquid
VG produces thick clouds even with small inhales.
❌ Exhaling Too Fast
Quick exhales push the remaining vapor out visibly.
❌ Not Doing the Second Inhale
Without fresh air dilution, the vapor cloud remains too dense.
❌ Using High-Wattage Sub-Ohm Devices
Big coils = big clouds, not suitable for zeroing.
Can You Zero a Disposable Vape?
Yes. Disposables are actually very good for zeroing because:
- They produce moderate vapor
- They have fixed the low wattage
- The airflow is limited
- They use nicotine salts (lower cloud output)
Just remember to take small hits and hold longer.
Is Zeroing a Vape Bad for You? (Health Perspective)
Zeroing requires holding vapor longer, which may increase:
- Nicotine absorption
- Lung irritation
- Exposure time to chemicals
While zeroing is just a technique, vaping in general carries health risks.
According to the CDC, e-cigarette aerosol can contain harmful substances such as nicotine, ultrafine particles, and volatile compounds—not just “harmless vapor.”
The FDA also warns that no vaping method is risk-free and that e-cigarettes contain nicotine, which is addictive.
⚠️ Zeroing does not make vaping safer; it only reduces visible vapor.
Safer Alternatives to Zeroing
If stealth is the goal, these alternatives may reduce stress on the lungs:
- Step away briefly instead of zeroing
- Reduce nicotine strength
- Use lower-wattage devices
- Switch to zero-nicotine if appropriate
- Take shorter, lighter puffs
⭐ FAQ — How to Zero a Vape
1. Does zeroing completely hide vape smoke?
It reduces or eliminates visible vapor, but not necessarily odor or chemicals.
2. Does zeroing increase nicotine absorption?
Holding vapor longer can increase absorption.
3. Is zeroing easier on disposables?
Yes — most disposables make smaller clouds.
4. Why can’t I make the vapor disappear?
Likely due to:
- High VG juice
- Taking too big a puff
- Not holding long enough
- No second inhale
5. Does zeroing damage your lungs?
Zeroing increases exposure time, but the CDC states vaping in general is not harmless.
