Decoding Vape Juice Labels: What’s in Your E-Liquid?


Vape juice, also known as e-liquid, is the lifeblood of the vaping experience. To make informed choices about what you’re inhaling, it’s essential to decode the information presented on vape juice labels. In this guide, we’ll break down the key elements you should look for on vape juice labels to understand what’s in your e-liquid.

Nicotine Concentration

One of the most critical pieces of information on a vape juice label is the nicotine concentration. This is usually expressed in milligrams per milliliter (mg/mL). It’s important to choose a nicotine level that aligns with your needs and preferences, whether you’re looking to quit nicotine altogether or are transitioning from smoking to vaping.

  • Low Nicotine (0-6 mg/mL): Suitable for vapers who are looking to reduce or eliminate nicotine intake.
  • Medium Nicotine (6-12 mg/mL): Ideal for former moderate smokers.
  • High Nicotine (12-18 mg/mL): Suited for ex-smokers who consumed a significant number of cigarettes per day.
  • Very High Nicotine (18+ mg/mL): Used by heavy smokers who are transitioning to vaping.

PG/VG Ratio

Vape juices contain two primary base liquids: Propylene Glycol (PG) and Vegetable Glycerin (VG). The ratio of these two liquids can significantly impact your vaping experience. A common way to express this ratio on labels is in a format like 70/30 or 50/50, with the first number representing the percentage of PG and the second number representing the percentage of VG.

  • High PG (e.g., 70/30): Provides a stronger throat hit and carries flavor effectively but produces less vapor.
  • High VG (e.g., 30/70): Offers a smoother inhale, larger vapor clouds, and is often chosen by cloud chasers.

Flavor Profile

The vape juice label should clearly indicate the flavor profile. This can be a simple nic salt juice descriptor like “strawberry” or a more complex flavor like “strawberry cheesecake.” Understanding the flavor profile is essential to ensure you’re choosing a vape juice that suits your taste.


Vape juice ingredients should be listed on the label. The primary components include:

  • Propylene Glycol (PG): This base liquid is thin and colorless, used to carry flavor and provide a throat hit.
  • Vegetable Glycerin (VG): A thicker and sweeter base liquid that contributes to vapor production and a smooth inhale.
  • Nicotine: If present, the nicotine content should be clearly indicated.
  • Flavorings: Flavorings used in the vape juice, which can be natural extracts or synthetic compounds.

Nicotine Warnings

In many regions, vape juice labels are required to carry nicotine warnings. These warnings typically inform you that nicotine is an addictive substance and can be harmful. It’s crucial to take these warnings seriously and be aware of the potential health risks associated with nicotine consumption.

Manufacturer Information

The label should also provide information about the manufacturer or brand, which allows you to identify the source of the vape juice. It’s a good practice to buy vape juice from reputable and well-known manufacturers to ensure product quality and safety.

Batch and Expiry Dates

Vape juice labels should include batch and expiry dates. This information helps you track the freshness of the product and ensure that it’s within its recommended shelf life.

Child Safety Warnings

Labels often include child safety warnings. Vape juice should be stored out of the reach of children and pets, as nicotine can be toxic if ingested or absorbed through the skin.

Additional Information

Some labels may provide additional information, such as instructions for use, recommended wattage ranges for vaping, and any specific storage conditions.

In conclusion, decoding vape juice labels is essential for making informed decisions about the e-liquid you’re using. Pay close attention to nicotine concentration, PG/VG ratio, flavor profile, ingredients, nicotine warnings, manufacturer information, batch and expiry dates, and any child safety warnings. By understanding what’s in your vape juice, you can ensure that your vaping experience is safe and tailored to your preferences.
