You’ve seen the photos. Maybe you’ve even seen the TikToks. They usually show a person looking vibrant and "normal," followed by a hospital bed or a drastic change in skin and energy. But the reality of people before and after vaping is rarely that cinematic. It’s actually a lot more subtle, a lot more chemical, and honestly, a bit more frustrating than a simple "before and after" filter can capture.
Vaping was sold as the "clean" alternative. A way to get off the sticks. But as the years have rolled on, the data from the CDC and independent researchers like those at Johns Hopkins has started to paint a picture that isn't just about "vapor" vs. "smoke." It’s about how the body adapts—and sometimes fails to adapt—to a constant intake of heated aerosols.
The shift is real.
The First Few Months: The Honeymoon Phase
When most smokers make the switch, the "after" looks great. At first. If you talk to someone who just swapped a pack-a-day habit for a Juul or a Vuse, they’ll tell you they can taste food again. Their clothes don't smell like a dive bar. This is the version of people before and after vaping that the industry loves to highlight.
The science backs this up to a point. According to a study published in the Journal of the American College of Cardiology, smokers who switched to e-cigarettes saw a significant improvement in their vascular function within just one month. Their blood vessels became less "stiff." This is the immediate win.
But then, things start to plateau.
The "after" starts to involve a different kind of cough. It's not the heavy, phlegm-filled "smoker's cough," but a dry, persistent throat irritation. This is often caused by propylene glycol and vegetable glycerin—the base liquids in almost every vape juice. They’re humectants. They literally suck the moisture out of your mouth and throat.
What Happens to the Skin and Face?
People care about their looks. It's human nature. One of the biggest search trends regarding people before and after vaping revolves around "vape face." While we don't have a 50-year longitudinal study like we do with cigarettes, dermatologists are sounding the alarm.
Nicotine is a vasoconstrictor. It shrinks your blood vessels.
When you vape, you’re often getting a higher, more consistent dose of nicotine than you ever did with cigarettes because you can do it indoors, at your desk, or in bed. This constant constriction means less oxygen and fewer nutrients are reaching the surface of your skin.

- Elasticity: Over time, the breakdown of collagen happens faster.
- Healing: If you get a breakout or a cut, it takes longer to heal.
- The "Grey" Look: Many long-term vapers notice a slight sallow or greyish tint to their complexion.
Dr. Mervyn Patterson, a cosmetic doctor, has noted that the inflammatory response triggered by the chemicals in e-liquids can exacerbate conditions like acne or rosacea. So, while you might not have the "smoker lines" around your lips yet, the "after" of vaping often includes puffiness and a loss of that natural glow.
The Lung Reality: It’s Not Just Water Vapor
Let's be clear: it was never water vapor. It’s an aerosol.
The biggest difference for people before and after vaping is often found in the small airways of the lungs. In 2019, the EVALI (e-cigarette, or vaping, product use-associated lung injury) outbreak scared the world. While most of those cases were linked to Vitamin E acetate in illicit THC carts, it opened a door into how the lungs react to foreign oils.
When you inhale these substances, your immune system's "clean-up crew"—the alveolar macrophages—try to eat the oil droplets. They get "constipated," for lack of a better word. They can’t do their job of protecting you from bacteria and viruses. This is why some vapers find themselves getting nastier colds or lingering bronchitis compared to their "before" life.
The Brain and the "Nicotine Loop"
The mental shift is perhaps the most profound change.
Most people before and after vaping notice a change in their anxiety levels. It’s a paradox. You vape to feel relaxed, but the "after" version of you is actually more stressed. Why? Because you're in a constant state of micro-withdrawal.
Nicotine salts, which are used in most disposables like Elf Bar or Lost Mary, are designed to hit the brain in seconds. They use benzoic acid to lower the pH, making the hit smooth enough to take a massive pull without coughing. This spikes your dopamine. But what goes up must come down.
The "after" vaper is often someone who can't sit through a 90-minute movie without checking their pocket. They become restless. The focus "boost" they thought they were getting becomes a requirement just to feel "baseline."
Beyond the Physical: The Lifestyle Creep
In the "before" days, smoking was a destination. You had to go outside. You had to stop what you were doing.

The "after" of vaping is a seamless integration into life. This sounds like a benefit, but it's actually the biggest trap. Because it's "cleaner," people do it more. They do it in the car, in the bathroom, and even under their shirt in public places.
This leads to a much higher total nicotine consumption. We are seeing a generation of people who are more addicted to nicotine than the heavy smokers of the 1970s.
The Teeth and Oral Microbiome
Dentists are seeing a specific "after" effect too.
Vaping changes the microbiome of your mouth. It makes it "stickier." Research from NYU College of Dentistry found that e-cigarette users have a unique oral microbiome that is more prone to inflammation and infection.
The sugar-like flavorings (think "Blue Razz" or "Mango") combined with the drying effect of the vapor create a breeding ground for bacteria.
- Gums start to recede because of the vasoconstriction.
- Cavities appear in places they didn't before.
- Breath becomes "funky" in a way that mints can't quite fix.
What About the "After" of Quitting Vaping?
This is the "after" that actually matters. What happens when you stop?
The good news is that the body is incredibly resilient. Within 20 minutes of your last puff, your heart rate drops. Within 24 hours, your blood levels of carbon monoxide (if you were a dual user) return to normal.
But the real "after" magic happens around the one-month mark.
Many people report that their "brain fog" finally lifts. The anxiety of needing to have a device on them 24/7 disappears. Their skin starts to look hydrated again. They find they have more "natural" energy because their sleep isn't being disrupted by middle-of-the-night nicotine cravings.

Actionable Steps: Moving Toward Your Best "After"
If you're looking at your own "before and after" and don't like what you see, there are concrete ways to pivot.
1. Track the "Ghost Puffs" For three days, don't change your habit, but just notice every time you reach for the vape without thinking. Most vaping is unconscious. Identifying these "ghost puffs" is the first step to breaking the loop.
2. Hydrate Like It’s Your Job Since vaping actively dehydrates your tissues, you need to double your water intake. This won't fix the chemical damage, but it will help with the "vape face" and the dry mouth issues.
3. Switch to Freebase Nicotine If you’re using high-strength nicotine salts (5% or 50mg), you’re on the "hardest" version of the drug. Switching to a lower-strength freebase nicotine (like 3mg or 6mg) makes the "hit" harsher, which naturally encourages you to do it less.
4. The 15-Minute Rule When the urge hits, tell yourself you can vape in 15 minutes. Often, the peak of the craving passes in about 5 to 10 minutes.
5. Get a Professional Oral Cleaning If you've been vaping for a year or more, go to the dentist. Get a deep clean to remove the biofilm buildup that's specific to e-cigarette use.
The story of people before and after vaping is still being written. We don't have the "end of the book" yet because the products haven't been around long enough for us to see the effects in 70-year-olds. But we know enough now to see that the "vapor" isn't just air—and the "after" is a version of yourself that your "before" self might not recognize.
Focus on the lung health you can regain now. Your future self is the one who will have to live in that "after" body. Make sure it's a place you actually want to be.
