⚡ Quick Answer
CBD vape pens are safe when they come from brands that publish third-party lab results and use clean ingredients, meaning zero cutting agents like vitamin E acetate, PG, PEG, or MCT oil. The 2019 EVALI outbreak wasn’t caused by CBD itself. It was caused by dirty additives in unregulated carts. Know what’s in your oil, check the COA, and you’re in good shape.
Are CBD Vape Pens Actually Safe?
CBD vape pens can be safe, but only if you know exactly what’s in them.
The CBD vape market is enormous, and the people using it deserve a straight answer about what they’re putting in their lungs.
The honest answer is this: the cannabinoid CBD itself isn’t the safety concern. CBD has been studied extensively: the FDA approved a CBD-based medication (Epidiolex) for epilepsy, and the WHO concluded in a 2018 report that “CBD exhibits no effects indicative of any abuse or dependence potential.” The safety question is entirely about the other stuff in the cartridge: the carrier oils, cutting agents, thinners, and flavoring chemicals that shady brands add without disclosing.
Translation: if you’re buying lab-tested CBD vapes from a brand that publishes full Certificates of Analysis and discloses every single ingredient, your risk profile is dramatically lower than someone buying an unlabeled cart at a gas station. The difference between those two scenarios is the entire ballgame.

CBD Vape Side Effects: What the Research Shows
Most people who vape CBD don’t notice much beyond the CBD itself. In clinical studies, the side effects seen most often are tiredness, diarrhea and changes in appetite, mostly at the high oral doses used for epilepsy (Iffland and Grotenhermen, 2017). Vaping can add throat irritation or a cough.
The study behind the scary headlines. In 2023, Roswell Park researchers found that a store-bought CBD pod caused more lung inflammation in mice than a Juul (Bhat et al., 2023). Look at what was in the pod, though: CBD dissolved in MCT oil plus a mix of flavoring chemicals. The study didn’t test CBD without them, so it can’t say which ingredient did the damage. It’s a strong case for the ingredient list below, and a reminder that inhaling anything puts your lungs to work. If you have asthma or COPD, see who should skip CBD vaping further down.
The EVALI Wake-Up Call (And What It Actually Means)
In 2019, emergency rooms across the U.S. started seeing a surge of patients with severe respiratory illness. The CDC eventually called it EVALI: e-cigarette or vaping product use-associated lung injury. It scared a lot of people, and rightfully so.
Here’s what the data actually showed: the majority of EVALI cases were tied to vitamin E acetate, a low-cost oil-based additive used by illicit THC cart manufacturers to cut their product and increase margins.
It was not CBD. It was not THC. It was a filler additive from unregulated products sold outside of the legal market.
CDC lab testing tied EVALI to vitamin E acetate, an additive used to thicken THC vape oil. It turned up in lung fluid from 48 of 51 patients tested and in none of the healthy comparison group (Blount et al., 2020).
Source: Blount, B.C. et al. (2020). “Vitamin E Acetate in Bronchoalveolar-Lavage Fluid Associated with EVALI.” New England Journal of Medicine, 382(8), 697-705.
The good news: EVALI cases dropped dramatically after the CDC identified vitamin E acetate as the primary culprit and issued public warnings. The lesson for consumers: your safety is directly tied to the quality verification of the specific product you’re buying. A lab-tested, clean-ingredient CBD vape from a licensed hemp brand is a fundamentally different product from an unverified cart.
⚠️ Red Flag Alert
If a CBD vape brand cannot show you a current, batch-specific Certificate of Analysis from a named third-party lab, do not buy it. That’s not cynicism. That’s just basic consumer protection in a category where product quality cannot be assessed by looking at the packaging
7 Ingredients to Avoid in CBD Vape Pens
Most CBD vape pens on the market have more than two ingredients (our guide Can CBD Oil Be Vaped? covers whether you can at all). The question is which additional vape ingredients are safe, and which ones are a red flag. Here’s the definitive list of what you should never see on a CBD vape label or COA:
1. Vitamin E Acetate (Tocopheryl Acetate)
This is the big one. Vitamin E acetate is safe when consumed orally or applied to skin, but when inhaled, it behaves like a greasy film that coats lung tissue and blocks gas exchange. The CDC directly linked it to the 2019 EVALI outbreak. There is zero legitimate reason for vitamin E acetate to be in a vape cartridge. If you see it listed, hard pass.
2. Propylene Glycol (PG)
Common in nicotine e-cigarettes as a carrier fluid. It’s generally recognized as safe for oral consumption by the FDA, but when it’s heated to vaping temperatures, PG gives off formaldehyde (Troutt and DiDonato, 2017). It doesn’t belong in a quality CBD vape. Shopping for THC vapes instead? Here’s whether THCa vapes are safe.
3. Polyethylene Glycol (PEG)
Another e-cigarette industry staple that made its way into cannabis vapes. When overheated, PEG can produce acetaldehyde and formaldehyde, both of which are known carcinogens. In the same 2017 lab study, one puff of heated PEG 400 produced about as much formaldehyde as smoking one cigarette. PEG is a vape thinning agent, not a necessary ingredient. A quality CBD oil should be thick enough on its own.
4. MCT Oil (Medium-Chain Triglycerides)
MCT oil is genuinely healthy when eaten. It’s used in keto diets and wellness products everywhere. But inhaling any oil can cause lipoid pneumonia, a condition where fat particles accumulate in lung tissue. MCT oil has no place in a vaporized product, period.
5. Diacetyl and Acetyl Propionyl
Flavoring chemicals most common in butter and caramel-flavored vapes. Diacetyl is associated with “popcorn lung” (bronchiolitis obliterans), a serious and irreversible lung condition. Some “natural flavors” in low-grade vapes mask these chemicals. Always ask for a flavoring ingredients disclosure.
6. Artificial Food Flavoring Chemicals
A flavoring chemical that’s FDA-approved for food isn’t necessarily safe to inhale. The FDA’s GRAS (Generally Recognized As Safe) status applies to oral consumption only. Many artificial flavor compounds have no inhalation safety data. When in doubt, choose a CBD vape with natural terpenes for flavor. They double as functional cannabinoids and have published safety profiles.
7. Vague “Proprietary Blend” or “Natural Flavors” Without Disclosure
If a brand won’t tell you exactly what flavoring compounds are in their vape, that’s a problem. “Natural flavors” is a catch-all FDA term that can include hundreds of different chemical compounds. Demand specificity. A brand that knows their product is clean will be proud to disclose every ingredient.
What a Clean CBD Vape Pen Should Actually Contain
If the ingredients-to-avoid list felt overwhelming, here’s the cleaner version: a genuinely clean CBD vape pen has very few ingredients. That’s the whole point.
- Hemp-derived CBD extract (distillate, full-spectrum or broad-spectrum oil, or live resin): the active ingredient. Should be third-party tested for potency and purity.
- Natural terpenes: for flavor and the entourage effect. Either cannabis-derived (CDTs) or botanical (BDTs). Both are fine. These should be disclosed by name (e.g., “myrcene, limonene, beta-caryophyllene”).
- That’s it. Two ingredients. Sometimes three if there are multiple cannabinoids (like CBG or CBN added for a specific effect).
A 510-thread CBD cartridge or a CBD disposable vape pen that contains those ingredients, and only those ingredients, with a clean COA to back it up is about as clean as an inhalation product gets.
Here is what goes into CBD vape carts: pure hemp-derived oil with no additives, no cutting agents, no PG, no PEG, no MCT oil, no artificial flavors. Every batch is third-party tested for potency, our raw materials are full-panel tested for purity (solvents, pesticides, heavy metals, mycotoxins, microbials), and the COAs are on our lab results page. Because if we wouldn’t put it in our own body, we’re not putting it in yours. You can compare those pens and carts in our CBD pens for anxiety collection.
How to Read a CBD Vape Lab Report (COA) in 5 Minutes
COA stands for Certificate of Analysis. It’s the third-party lab report that tells you exactly what’s in (and not in) your CBD vape. Reading one sounds intimidating, but you really only need to check five things:
- Potency Panel
Check that CBD content matches what’s on the label (within ~10% variance is acceptable). Also scan for THC. Under the 2018 Farm Bill hemp definition, which is subject to change, hemp products have been held to 0.3% Delta 9 THC or less by dry weight. - Pesticide Panel
Every pesticide should show “ND” (non-detect) or a value below the state action limit. Hemp is a bioaccumulator: it soaks up pesticides from soil aggressively. If the pesticide panel is missing from the COA, that’s a major red flag. - Heavy Metals Panel
Lead, mercury, arsenic, and cadmium should all be ND or below California Prop 65 limits. Again, hemp bioaccumulates metals from contaminated soil. U.S.-grown, tested hemp is your safest bet. - Residual Solvents Panel
During extraction, some brands use hydrocarbon solvents (butane, propane, hexane). These should be completely purged before the oil ends up in a cart. Look for ND on all solvents. - Lab Credentials & Date
The lab should be ISO 17025 accredited (look for the accreditation number). The COA should be dated within the last 12 months and be batch-specific, not a generic report that applies to “all products.” If you can’t find the lab’s name or it’s a brand-affiliated lab, proceed with extreme skepticism.
Pro tip: if you can’t find current, batch-specific lab results on a brand’s website or behind a QR code on the box, that tells you everything you need to know. Our CBD live resin disposable vape pen is two ingredients, with a public COA for every batch.

Vaping CBD vs. Smoking: Which Is Safer for Your Lungs?
This is a fair question and the science has something useful to say. When you combust anything (flower, hemp, tobacco), you produce carbon monoxide, tar, and benzene, none of which are things you want in your lungs on a regular basis. These combustion byproducts are responsible for the majority of smoking-related lung damage.
Vaping avoids combustion (assuming you’re vaping below ~370°F / 188°C). No combustion = no CO, no tar, no benzene from the burning process. That’s a genuine advantage.
However, “safer than smoking” is not the same as “safe.” Here’s what we do and don’t know:
| Consideration | Vaping CBD (clean product) | Smoking CBD Flower |
| Combustion byproducts | None (if below combustion temperature) | CO, tar, benzene from burning |
| Onset speed | Very fast, 1–3 minutes | Very fast, 1–3 minutes |
| Long-term inhalation data | Limited, still emerging | More established for tobacco; hemp data limited |
| Risk if product is unverified | High: additives are invisible without lab testing | Moderate: combustion risks visible/known |
| Throat irritation | Generally lower with quality products and proper temp | Higher from combustion |
The bottom line: a clean, lab-verified CBD vape is likely a lower-risk inhalation method than smoking. But “likely lower risk” isn’t a green light to vape 40 times a day. Moderation and product quality are the two variables entirely within your control. Coming from nicotine e-cigs? Our nicotine-free vape pens have hemp extract and terpenes in the oil, and that’s the whole list.

Who Should Avoid CBD Vaping
Even with a perfectly clean product, vaping isn’t for everyone. Be cautious or consult a physician first if you:
- Have asthma, COPD, or any chronic respiratory condition: inhalation products can trigger irritation regardless of what’s in them
- Are pregnant or nursing: there’s insufficient safety data on inhaled cannabinoids during pregnancy
- Are under 21: TribeTokes products are for adults only; developing lungs and brains deserve extra caution
- Take medications metabolized by CYP450 enzymes: CBD is a known CYP450 inhibitor and can affect how certain drugs (blood thinners, anti-epileptics, some antidepressants) are processed by your body. Talk to your pharmacist.
- Have a history of bronchospasm or hypersensitivity reactions to inhaled substances
If any of those apply, CBD gummies, tinctures, or topicals may be a better fit. We’ve got guides on those too, and no, we won’t judge your method of choice.
How to Choose a Safe CBD Vape Pen: 6-Point Checklist
Here’s a printable (okay, screenshot-able) checklist for your next purchase:
- Find the COA. If it’s not on the brand’s website or behind a QR code, stop here. Move on.
- Verify the lab. Google the lab name. Confirm ISO 17025 accreditation and that it’s genuinely independent (not owned by the brand).
- Read the ingredient list. Should be 2–3 items: hemp-derived CBD oil, terpenes, possibly other cannabinoids. Any additive you don’t recognize is a reason to ask questions.
- Check for the kill-list ingredients. Scan for vitamin E acetate, PG, PEG, MCT oil, or diacetyl. One hit = hard pass.
- Confirm U.S.-grown hemp. Domestic hemp is subject to USDA oversight. Imports carry more uncertainty around soil quality and agricultural practices.
- Look at real reviews. Not curated testimonials. Check Trustpilot, Reddit, and third-party review aggregators. Patterns in customer feedback (throat burn, inconsistent effects, weird taste) are data points.

Frequently Asked Questions
CBD vape pens from reputable brands that use clean, lab-tested oil with no additives like vitamin E acetate, PG, or artificial thinners are generally considered safe for most healthy adults. The risk comes from low-quality products with unverified ingredients. Always check for a current Certificate of Analysis (COA) from a third-party lab before purchasing.
Avoid CBD vape pens containing vitamin E acetate, propylene glycol (PG), polyethylene glycol (PEG), MCT oil, diacetyl, artificial flavoring chemicals, or any undisclosed “proprietary blend.” These additives have been linked to lung irritation and, in the case of vitamin E acetate, severe lung injury (EVALI).
Vitamin E acetate is an oil-based additive that was widely used as a cutting agent in illicit vape cartridges. The CDC identified it as a primary cause of the 2019 EVALI outbreak, which hospitalized over 2,700 people. When inhaled, it coats lung tissue and impairs gas exchange. It should never appear in any vape product.
Check five things: (1) cannabinoid potency panel confirms CBD content matches the label, (2) pesticide panel shows ND on all listed pesticides, (3) heavy metals panel shows ND or values below limits for lead, mercury, arsenic, and cadmium, (4) residual solvents panel shows ND, and (5) the report is dated within the last 12 months and comes from a named ISO-accredited third-party lab.
Vaping CBD at low temperatures (under 370°F / 188°C) avoids combustion, which means no carbon monoxide or tar, two main harmful byproducts of smoking. However, vaping is not risk-free, and the long-term effects of inhaled cannabinoids are still being studied. Clean-ingredient CBD vape pens are generally considered a lower-risk inhalation method compared to combustion, but product quality is everything.
EVALI (e-cigarette or vaping product use–associated lung injury) was an outbreak in 2019 linked primarily to vitamin E acetate in illicit vape carts. The CDC reported 2,807 hospitalized cases and 68 deaths by February 2020. The risk from licensed, lab-tested CBD brands is very low, but unregulated or gray-market products remain a concern. Verify the COA.
Hemp-derived CBD has been sold under the 2018 Farm Bill hemp definition, which is subject to change, and state rules vary. Buy from brands that publish lab results showing Delta 9 THC levels.
Low-quality CBD vapes containing harmful additives can cause lung irritation or injury. High-quality CBD vapes using pure hemp-derived oil with no cutting agents have a much lower risk profile. Any inhalation product carries some lung exposure. If you have asthma, COPD, or other respiratory conditions, consult a physician before vaping.
A clean CBD vape pen should contain hemp-derived CBD extract (distillate, full-spectrum or broad-spectrum oil, or live resin), natural terpenes, and nothing else. No cutting agents, no artificial flavors, no PG, no PEG, no MCT oil, no vitamin E acetate. Two to three ingredients max, and every ingredient should be verifiable on the COA.
A trustworthy CBD vape brand will publish current batch-specific COAs on their website, use a named ISO-accredited third-party lab, fully disclose all ingredients, have verifiable customer reviews, comply with GMP standards, and clearly state their hemp source. U.S.-grown is preferred. Avoid brands that don’t publish lab results or are vague about what’s in their products.
No. CBD doesn’t produce a high. Full-spectrum oil carries trace THC within hemp limits, not enough to feel. If you get drug tested, an isolate or broad-spectrum pen keeps THC out of the picture.
There’s little long-term human data on daily CBD vaping. If you vape daily, stick to clean, lab-tested oil, take fewer, shorter pulls, and stop if you notice a cough or chest tightness.
