Now that you’ve got your favorite vaping liquid, you don’t ever want to run out of it. But what happens when you are down to your last bit and there’s no way to get more soon enough? The solution many people turn to is adding water to their e-liquid, but is this really a good idea?

Many products can be diluted with water to tone their flavor down or to create more, like your shampoo or liquid soap. You are not ingesting those, though, so it’s not that big of a deal. When it comes to your e-liquid, or anything you inhale into your body, you want to know the whole scoop of what you are doing so you can do it safely.

Here’s the lowdown on mixing e-liquid with water and what it does.

E-Liquid and Water – Do They Mix?

When you get your e-juice, it may be thicker than your previous bottle. This is quite common, but it may cause you to want to thin it out some. Before you do, you should understand why your favorite e-liquid is not always the same consistency.

The thickness of e-liquids is mostly based on how much vegetable glycerin (commonly known as VG) is in the bottle. VG is used in a variety of ingestible and wearable products, such as makeup and foods. It’s made from vegetable oil and is a natural solvent that produces the cloud effect in your vaping. Toning down the VG means less cloud, but it is not always easy to get the exact same amount of VG in every bottle.

The flavor of your e-liquid is created from different ingredients, but it is enhanced by the PG in it. PG, or propylene glycol, gives you the coveted throat hit that makes the perfect vape. However, each vape juice has a varying combination of PG and VG.

You have probably seen blends on your vape bottles, even if you didn’t know what they meant. The typical favorite blends that work well are 80/20 VG/PG, 70/30 VG/PG, 60/40 VG/PG, and 50/50 VG/PG. It’s always the amount of vegetable glycerin over the amount of propylene glycol.

With these content amounts in mind, before you decide to dilute your e-liquid with water, you might instead try one with less VG in it. The extra VG makes a thicker vape but makes it harder to inhale.

Should You Still Add Water?

If you absolutely can’t find the thickness that you enjoy, you might benefit from diluting your e-juice with a tiny bit of water. The recommended ratio is one drop of distilled water per 2 mL of e-liquid. Start with this small concentration and play around until you get the consistency that you like.

Be aware of the possible complications, though. Adding water to your e-juice means you are inhaling extra H2O into your lungs. This is a great way to get yourself sick. Introducing water into your lungs without knowing exactly what you are doing means exposing yourself to infections that may not have otherwise existed.

There’s a reason the amount of water in e-liquids is what it is, so let the experts do their thing while you enjoy your vape. If you must experiment, do so carefully.
