What is Vaping? Everything Beginners Need to Know in 2025

Vaping is the act of inhaling vapor created by an electronic device, known as a vape or e-cigarette. For many adults, it’s a modern alternative to smoking, designed to deliver nicotine or flavors with fewer harmful by-products than traditional cigarettes.

The vapor comes from a liquid called vape juice or e-liquid, which may contain nicotine and comes in countless flavors. The nicotine strength and flavor are completely customizable, making vaping a flexible option for adult users.


A Quick History of Vaping

The first commercial vape was created in the early 2000s by Chinese pharmacist Hon Lik, aiming to provide a smoke-free alternative for smokers. His product, resembling a cigarette, hit the market in China before reaching the U.S. and Europe around 2007.

Since then, vaping devices have evolved dramatically, offering everything from small disposable vapes to advanced, customizable mods for hobbyists.


How Does a Vape Work?

All vapes operate using the same core components:

Battery (Mod): Powers the device
Heating Element (Coil): Heats the e-liquid
Tank/Pod (Atomizer): Holds the e-liquid
Mouthpiece: Allows the user to inhale

When activated, the battery heats the coil, which turns the e-liquid into vapor ready for inhalation.

Device Types Include:

  • Pod Systems: Compact, user-friendly
  • Vape Pens: Slim and portable
  • Box Mods: High-powered, customizable
  • Disposable Vapes: Ready-to-use, single-use

Pro Tip: New users should opt for devices with built-in rechargeable batteries for ease of use and safety.


Vape Juice: What’s Inside?

Vape juice (e-liquid) is made from:

Vegetable Glycerin (VG)
Propylene Glycol (PG)
Flavorings
Nicotine (optional)

The ratio of VG to PG affects vapor production and throat hit. Higher VG produces thicker clouds, while higher PG provides stronger flavor and sensation.

Choosing Nicotine Strength:

12–60 mg (High)Small devices, mouth-to-lung (MTL)
6–12 mg (Medium)Medium devices, versatile use
0–6 mg (Low)Large devices, direct-lung (DL)

How to Inhale a Vape Correctly

Inhaling the right way enhances your vaping experience and prevents coughing.

Two Main Techniques:

1️⃣ Mouth-to-Lung (MTL)

  • Similar to smoking a cigarette
  • Works best with high-resistance coils and high nicotine

Steps:
✅ Draw vapor into your mouth
✅ Hold for a second
✅ Inhale into lungs
✅ Exhale


2️⃣ Direct-Lung (DL)

  • More vapor, smoother inhale
  • Ideal with sub-ohm coils and low nicotine

Steps:
✅ Inhale directly into lungs
✅ Exhale immediately

Not Sure?

  • Use MTL for higher nicotine
  • Use DL for lower nicotine

What Should You Vape?

Only use your device with approved vape juice. Avoid experimenting with:

⛔ Cooking oils
⛔ Household liquids
⛔ Syrups, alcohol, or soda
⛔ Cannabis products (unless labeled for vaping)

CBD e-liquids formulated for vapes are acceptable, but use the correct device.
