What is Freebase Vape Juice? The OG of E-Liquids.

Freebase vape juice is one of the most common and traditional types of nicotine used in e-liquids. Unlike nicotine salts, freebase nicotine is chemically altered to increase its pH level, making it easier to vaporize and producing a stronger throat hit. Freebase e-liquid is typically used in high-powered vape devices and is ideal for those who enjoy bold flavor and intense vapor production.

Why choose freebase e-liquids?

  • Stronger Throat Hit - Freebase nicotine delivers a sharper, more noticeable throat hit due to its higher pH levels, especially at higher nicotine strengths.
  • Better Flavor - They are often used in sub-ohm devices, they produce larger clouds and allow for more intense, cleaner flavor profiles.
  • Lower Nicotine Strengths - Regular e-juice typically comes in lower nicotine levels (like 3mg, 6mg, or 12mg). Additionally, nicotine free vape juice is an available option, unlike nicotine salt.
  • Ideal for Sub-Ohm Vaping - Freebase e-liquid works best in high-wattage, sub-ohm vape setups—perfect for direct-to-lung (DTL) inhales and big cloud production.
  • Widely Available & Affordable - Freebase vape juice has been around the longest, so you’ll find a huge variety of flavors, brands, and price points.

Frequently Asked Questions

What is vape juice made out of?

E-juice is primarily made from four main ingredients: propylene glycol, vegetable glycerin, flavorings, and optional nicotine. Here is a list of their primary roles.

  • Propylene Glycol - A thin, odorless liquid that helps carry the flavor in your vape juice and provides a throat hit similar to smoking. The higher the PG content, the stronger the throat hit.
  • Vegetable Glycerin - A thicker liquid that helps produce large vapor clouds and adds a smooth, slightly sweet taste. A higher VG ratio in your e-liquid results in bigger clouds and smoother hits.
  • Flavorings - They are food-grade, vapor-safe compounds that give vape juice its taste and are available in endless options, including fruity, candy, dessert, and tobacco flavors.
  • Nicotine - This ingredient in vape juice usually comes in 3 mg, 6 mg, or 12 mg strengths and can sometimes give you a buzz.

Do vapes contain sugar?

No, vape juice does not contain actual sugar. However, many e-liquids use sweeteners—like sucralose or ethyl maltol—to enhance flavor, especially in fruity or dessert-style vapes.

Does vape juice expire?

Yes, they do expire. Vape juice usually lasts 1-2 years from the manufacturing date, depending on storage and ingredients. Over time, the ingredients and nicotine can degrade, affecting both flavor and strength. Most manufacturers include a manufacturing date or expiration date, so it’s important to check before use.

Can you bring vape juice on a plane?

Yes, you can bring vape juice on a plane, but there are important guidelines to follow:

  • Carry-On Luggage: E-liquids must be in bottles of 3.4 ounces (100 ml) or smaller. You can bring multiple bottles, but they must all fit in a sealable, clear, one-quart-sized bag.
  • Check-In Luggage: There are no size restrictions for vape juice in checked luggage. Be sure to pack vape juice securely to avoid leaks or spills.
  • Usage: Vaping or charging your device on airplanes is strictly prohibited.
  • International Travel: If you're flying internationally, be sure to check the local laws and regulations regarding bringing vapes into the country.

What is diacetyl in vaping?

Diacetyl is a chemical compound used to create rich, buttery, or creamy flavor profiles in e-liquids. While it’s safe to consume in foods like microwave popcorn, inhaling diacetyl can lead to lung conditions, including bronchiolitis obliterans, commonly known as “popcorn lung."

Due to these health risks, most high-quality vape juice brands avoid using diacetyl in their products. That’s why it’s important to buy vape juice from reputable manufacturers that prioritize safety and transparency.
