Nicotine-free vapes are sold at dedicated vape shops, smoke shops, many convenience stores, and through online retailers. They’re easier to find than you might expect, though the labeling can be confusing depending on where you shop. Here’s what to know about finding them, what you’re actually buying, and what the health trade-offs look like.
Where to Buy Nicotine-Free Vapes
Your most reliable option is a dedicated vape shop, either online or in person. These stores typically stock a range of 0mg (zero nicotine) e-liquids and pre-filled disposable devices, and staff can point you to the right product. Smoke shops and some convenience stores carry them too, though the selection tends to be smaller and skewed toward disposables.
Large retailers like Walmart and Amazon take a different approach. Because of platform restrictions on vaping products, nicotine-free options sometimes appear under alternative names like “aromatherapy inhalers” or “personal diffusers.” These are functionally the same type of product, just marketed to fit the retailer’s guidelines. If you’re shopping on one of these platforms, searching for those terms will surface more results than searching for “vape.”
Types of Nicotine-Free Devices
Nicotine-free vapes fall into three broad categories, and the differences matter depending on what you’re looking for.
- Disposable 0mg vapes: Pre-filled, single-use devices (sometimes called “no-nic sticks” or “puff bars”). You use them until the liquid runs out and toss them. These are the simplest option and the most widely available.
- Refillable devices with 0mg e-liquid: Larger, rechargeable vape pens or mods that you fill with nicotine-free vape juice. These cost more upfront but less over time, and give you a wider selection of flavors.
- Wellness or vitamin vapes: Devices marketed as delivering ingredients like melatonin, B12, or essential oils. These are a distinct product category with their own set of concerns (more on that below).
How to Spot 0mg Products on the Label
The standard labeling for nicotine-free vape products is “0mg,” meaning zero milligrams of nicotine per milliliter of liquid. You’ll see this on the packaging, the device itself, or the online product listing. Some brands write it as “0% nicotine” or simply “nicotine-free.” All three mean the same thing: the e-liquid is formulated without any nicotine.
This label appears across every product format, from pre-filled disposable pods to bottled e-liquids in flavors ranging from menthol to bakery to citrus. If you’re buying in a store, check the packaging directly rather than relying on shelf placement, since nicotine and nicotine-free products often sit side by side.
Age Restrictions Still Apply
Federal law in the United States sets the minimum purchase age for all tobacco and e-cigarette products at 21. This applies to every retailer, online or in person, with no exceptions for military personnel or any other group. The law specifically covers electronic nicotine delivery systems and e-liquids.
Where it gets murkier is with truly nicotine-free products. The federal Tobacco 21 law targets products containing nicotine, so a genuinely 0mg device may not technically fall under that regulation. In practice, though, most retailers apply the same age restriction to all vaping products regardless of nicotine content. Many states have their own laws that explicitly cover nicotine-free vaping devices as well. Expect to show ID no matter what you’re buying.
What’s Actually in a Nicotine-Free Vape
The base liquid in a standard 0mg vape is a blend of vegetable glycerin, propylene glycol, and water. Manufacturers add flavoring chemicals to create specific tastes. Removing the nicotine doesn’t remove everything else. The aerosol you inhale still contains compounds produced when those base ingredients and flavorings are heated.
The CDC notes that vape aerosol can contain diacetyl, a flavoring chemical linked to lung disease. A 2018 study found that several common e-liquid flavoring ingredients triggered a damaging inflammatory response in lung cell samples. And research on adolescents who used only e-cigarettes (without traditional tobacco) found significantly higher levels of toxic chemicals in their urine, including acrylonitrile, acrolein, and acrylamide, compared to non-users.
Inhaling propylene glycol and vegetable glycerin on their own can irritate the airways and may increase the risk of lung infections. These are the base ingredients in virtually every vape product, nicotine or not.
Blood Vessel Effects Without Nicotine
One finding that surprises many people: nicotine-free vaping can affect your cardiovascular system after just one session. A study published in the journal Radiology and highlighted by the National Heart, Lung, and Blood Institute found that a single use of a nicotine-free e-cigarette reduced blood flow in participants. MRI scans showed normal, healthy blood flow before vaping and measurably constricted blood flow one hour afterward. This suggests that chemicals in the aerosol itself, not just nicotine, can damage blood vessels.
The Problem With “Wellness” Vapes
Devices marketed as melatonin vapes, vitamin B12 vapes, or essential oil diffusers occupy a gray area. They’re sold as wellness products rather than tobacco alternatives, which means they face less regulatory oversight. The FDA has issued a consumer update warning against their unproven health claims and misleading advertising.
A recent study published in PMC tested commercially available melatonin vapes and found they contained potential contaminants, including pharmaceutical compounds and industrial chemicals that weren’t listed on the label. When researchers exposed human lung cells to these products, the melatonin vape exposure suppressed immune-related gene activity and decreased the release of key immune signaling molecules. In plain terms, inhaling these products may impair your lungs’ ability to fight off infections. The devices didn’t kill lung cells outright in lab testing, but the changes at the cellular level were concerning enough that researchers flagged respiratory immune dysfunction as a real risk.
If you’re considering a wellness vape for sleep or vitamins, keep in mind that inhaling a compound and swallowing it are very different delivery methods. The safety profiles of melatonin or B12 as supplements don’t automatically transfer to inhaled versions, and the lack of regulation means you can’t be confident about what’s actually in the device.
Using 0mg Vapes to Quit Smoking
Many people seek out nicotine-free vapes specifically as a step-down tool, replacing the hand-to-mouth habit of smoking after they’ve already weaned off nicotine itself. The behavioral component of smoking, holding something, inhaling, exhaling a visible cloud, is a genuine part of the addiction, and a 0mg vape can address that ritual without reintroducing nicotine.
That said, the chemical exposure from vaping doesn’t disappear just because the nicotine is gone. The flavoring compounds, base liquid byproducts, and aerosol particles still enter your lungs. For someone transitioning away from cigarettes, a nicotine-free vape is almost certainly less harmful than continued smoking. But it’s not the same as breathing clean air, and treating it as a permanent replacement rather than a temporary bridge means accepting ongoing exposure to irritants and potentially toxic compounds.
