Are Plant-Based Vapes Safe? (In-Depth Look)

Most of the ads that warn against the dangers of vaping focus on the fact that vapes contain toxic chemicals, additives, and addictive nicotine. And while those facts are accurate, there are also plant-based vapes that don’t contain any of those things. So, are plant-based vapes safe?

There is a lot of debate around whether or not plant-based vapes are safe. Many people believe they can actually offer health benefits. Others believe that they’re just as dangerous as every other vape on the market.

Which is true?

We look at plant-based vapes in-depth, explore their potential benefits and risks, and provide top product recommendations that deliver nothing but plant-powered vapor.

Are Plant-Based Vapes Safe?

More scientific evidence is needed to determine if plant-based vapes are safe or unsafe. But we do know this:

They’re safer than many of the alternatives.

Plant-based vapes, like our MELO, are not e-cigarettes. They contain zero nicotine. They aren’t filled with vape juice or flavored e-liquids full of harmful chemicals. They do not contain THC, CBD, or tobacco. Instead, they include plant extracts, essential oils, and melatonin to help you sleep.

MELO makes personal aromatherapy diffusers, so they’re not vape pens in the traditional sense. In fact, MELO vapor doesn’t even have to be inhaled — you can use these devices retronasally.

The best and most effective way to hit a MELO diffuser is to draw the mist into your mouth and exhale it through your nose without drawing it into your lungs. Inhaling any vape of any type can potentially put foreign substances into your lungs, so this is an intelligent alternative.

For that reason alone, we consider our MELO vape safer than those requiring inhaling.

What Are the Potential Side Effects of Plant-Based Vapes?

Consider the potential dangers that exist before you start vaping. Medical experts warn that no vape is entirely harmless and that all have the potential to affect your health adversely. There are some common side effects you may experience when using plant-based vapes with essential oils.

Nose and mouth damage

Essential oils contain volatile organic compounds (VOCs) that become more harmful when heated over 150 to 180° Fahrenheit. VOCs can damage the nose, mouth, and teeth when breathed in or inhaled.

Lung damage

Vaping can cause lung inflammation, affect mucus production, and cause immune cells to malfunction. People with asthma and COPD are at greater risk and should avoid vaping altogether.


Coughing is one of the most common side effects of plant-based vapes, and some essential oils may make you cough more than others.

Nausea and dizziness

Even when vaped in low doses, essential oils may make you feel lightheaded, nauseous, or dizzy.

Allergic reactions

Essential oil compounds can trigger allergic reactions and result in itching, swelling, wheezing, and shortness of breath.

More research is needed to know all the potential side effects that may exist. People who are pregnant, have known allergies to essential oils, or have existing respiratory conditions should not vape.

Are Plant-Based Vapes Addictive?

Electronic cigarettes are electronic nicotine delivery systems, and they are highly addictive. As with smoking regular cigarettes, using e-cigarettes can lead to nicotine addiction in a short amount of time.

Some healthy vapes without nicotine do not contain any addictive substances. However, reading the ingredients list is essential to know what you’re putting into your body.

Keep in mind that the physical act of vaping essential oils can create a physiological addiction and an oral fixation. Many cigarette smokers are just as addicted to nicotine as they are to the physical act of repeatedly putting a cigarette between their lips.

Until there is more scientific evidence, we cannot say for sure if zero-nicotine vapes are entirely safe. But we can say with certainty that they won’t cause you to become addicted to nicotine.

What Are Alternatives to Plant-Based Vapes?

Plant-based vapes with essential oils represent a fraction of the vape market, and there are many alternative substances that you can vaporize. Some people vape flavored nicotine. Others prefer vaping cannabis concentrates. Some like the feeling of vaping herbal extracts.

The thing to keep in mind is that many vape juices include dangerous substances such as diacetyl, vitamin E acetate, and propylene glycol. Plant-based vapes like MELO and HELO don’t include these ingredients — they use natural and organic fruit-flavored extracts, deionized water, and vegetable glycerin.

Of course, there is another alternative altogether:

To not vape at all.

Essential oil vape pens are healthy vape alternatives to traditional vaping products. But if you like them for their essential oil benefits, many other ways exist to achieve those same effects.

Many people prefer to use essential oils in tabletop diffusers or humidifiers. Some enjoy adding oils to a bath. Others prefer to burn essential oil-infused incense cones, apply oils topically, or inhale them directly from the bottle.

If you like an essential oil vape with added ingredients like melatonin or caffeine, alternative ways exist to enjoy those same effects. For example, melatonin comes in many forms, including tablets, capsules, gummies, liquids, and patches. You can get an energy boost from consuming caffeine in gummies, tablets, or a good old-fashioned cup of coffee.

Many alternatives to vaping exist, so if you’re concerned about the potential dangers of vaping, there are other options out there.

What Are the Potential Benefits of Plant-Based Vapes?

We need more scientific data to say that plant-based vapes offer significant health benefits. We simply don’t know enough about them yet to make that claim. But many potential benefits are worth exploring.

Tobacco quitting assistance

We all know that cigarette smoking is bad for us. We also know that it’s a tough habit to quit. From gum to mints to patches, smoking cessation devices exist in multiple forms — but none of them provide the satisfaction of inhaling a resounding hit of nicotine into your lungs.

When you inhale ingredients from a zero-nicotine vape, you satisfy your oral fixation and enjoy that “smoking” feeling. There is no scientific evidence to suggest that vaping can help you quit smoking, but many ex-smokers agree that smoking a zero-nicotine vape made it a bit easier to quit.

Increased energy

Some plant-based vapes include caffeine, which can give you energy and help you power through the day.

Improved sleep quality

Some plant-based vapes include melatonin, which helps you sleep. Melatonin helps with the timing of your circadian rhythm and promotes sleep so you feel more well-rested in the morning.

Reduced stress

Plant-based personal diffusers look like traditional vape pens but provide the benefits of aromatherapy rather than a nicotine hit. While different essential oils have different effects on the brain, aromatherapy is proven to reduce stress, anxiety, and tension.

Aromatherapy can also ease headaches, boost immunity, reduce pain, and improve brain function.

There are pros and cons of vaping without nicotine. Yet despite the potential benefits they offer, zero-nicotine vapes are not subject to the same Food and Drug Administration guidelines as vapes that contain nicotine. The FDA does not put restrictions on non-nicotine vape devices or the ingredients used in them.

Always exercise caution when vaping, and be sure to use well-known and trusted brands that use natural ingredients as opposed to harsh chemicals.

What Are the Best Plant-Based Vape Product Options?

MELO Air Plant-Based Vapes in assorted flavors

If you’re looking for a healthier alternative to traditional vapes, opt for a plant-based vape that does not contain nicotine. We enjoy several on the market for different reasons, but we think MELO is the best nicotine-free vape.

MELO is designed for adults looking for new self-care methods. These vapes are free of nicotine, THC, CBD, and all other drugs. They include natural and organic ingredients and are free of vitamin E acetate, diacetyl, and other dangerous carrier substances found in many other vapes.

Yet, it’s the addition of melatonin that makes MELO devices genuinely unique.

Melatonin promotes sleep, which is crucial to our overall well-being. A lack of sleep can increase anxiety and stress, weaken your immune system, impair your brain function, and put you at higher risk for cardiovascular disease, diabetes, and weight gain. Sleeping is essential; taking melatonin can help you get the quality, restful sleep you need.

One disposable MELO Air vape offers about 400 puffs, while a MELO Plus vape pen provides about 800 puffs. Both are designed for use in moderation and come in various delicious flavors, such as Cotton Candy, Orange Dreamsicle, Banana, and Midnight Mint.

The other unique feature of MELO diffusers is that, as we explained, you don’t have to inhale the vapor into your lungs. You simply take the mist into your mouth and breathe it out through your nose. Many other vapes require you to inhale to experience their full effects.

If you’re looking for a vape that can give you energy instead of one that will help you sleep, check out MELO’s sister device, the caffeine diffuser HELO. HELO can make you feel refreshed and alert after just a few puffs. It is made with all the same constituents as MELO but with energizing caffeine instead of sleep-promoting melatonin as the active ingredient.

Where To Buy Plant-Based Vapes

All vapes have the potential to cause health risks, and once more research is conducted on plant-based vapes, it will be easier to understand their long-term effects. Vaping essential oils is relatively new, and research into its efficacy and risks is in its infancy. There could be risks that have not yet been discovered. Only time will tell.

Yet, considering how many vapes contain addictive nicotine, dangerous vitamin E acetate, and other harsh chemicals, many consumers consider our MELO and HELO devices to be some of the safest vapes by comparison. Made only with natural ingredients and free of all addictive substances and harsh chemical additives, MELO and HELO vapes stand out as some of the best on the market, both for what they contain and what they do not contain.
