What Is CBD Oil Vape?
The term “CBD oil vape” is used loosely across the internet to describe two different things: CBD vape juice (also called CBD e-liquid or CBD vape oil) that you fill into a refillable vaping device, and disposable CBD vape pens that come pre-filled and ready to use straight from the box. In both cases, cannabidiol (CBD) is delivered through inhalation, which means it absorbs into the bloodstream through the lungs rather than the digestive system.
The defining characteristic of a genuine CBD oil vape product is that it is specifically formulated for vaporising. It contains CBD extracted from legally grown hemp plants, suspended in a carrier liquid made from propylene glycol (PG) and vegetable glycerin (VG), combined with food-grade flavourings. This is what makes it safe to inhale. It is chemically very different from the CBD oil tinctures designed for oral use and the two must never be confused.
Can You Put CBD Oil in a Vape?
No and this is the most important point in this entire guide. Regular CBD oil cannot go in a vape device. Full stop.
Standard CBD tinctures for oral use are made with plant-based carrier oils such as MCT oil (from coconut), hemp seed oil, or olive oil. When these oils are heated to vaping temperatures and inhaled, the droplets can deposit in the lungs and cause a condition called lipoid pneumonia a serious inflammatory condition caused by oil in the lung tissue. Your vaping device is also very likely to clog, burn out, and fail.
What you need is a product specifically manufactured as a CBD vape juice or CBD e-liquid formulated with a PG/VG base rather than a plant-based oil. Before vaping anything, always confirm the label says “e-liquid”, “vape juice”, or “for inhalation.” If it says “oil” and is designed to go under the tongue, it is not for vaping.

CBD Oil vs CBD Vape Juice What’s the Difference?
The confusion between these two products is understandable — both are liquids that contain CBD and both come in similar-looking bottles. But the differences in formulation, usage, and effect are significant. The comparison table below gives you a full side-by-side breakdown.
The most important practical difference is speed of onset. When you vape CBD, it enters the bloodstream directly through the lungs, bypassing the digestive system entirely. Research indicates that the bioavailability of inhaled CBD is considerably higher than oral CBD studies suggest approximately 34–56% for inhalation compared to 6–19% for oral consumption. In plain terms, more of the CBD you vape actually reaches your system, and most people feel effects within 5–10 minutes rather than 15–45 minutes.
The trade-off is duration. CBD vape effects typically last 1–3 hours, whereas oral CBD oil or CBD gummies can sustain effects for 4–6 hours. If you need fast relief from anxiety or stress at a specific moment, vaping is the more effective delivery method. If you want steady background support throughout the day, oral drops or edibles are the better option.
| Feature | CBD Oil (Oral Tincture) | CBD Vape Juice (E-Liquid) |
|---|---|---|
| Carrier base | MCT oil, hemp seed oil, olive oil | Propylene glycol (PG) + vegetable glycerin (VG) |
| How to use | Drop under the tongue, hold 60 seconds, swallow | Fill vape device or use disposable pen, inhale |
| Onset time | 15–45 minutes | 5–10 minutes |
| Duration | 4–6 hours | 1–3 hours |
| Bioavailability | ~6–19% | ~34–56% |
| Can it go in a vape? | No — dangerous to inhale oil carriers | Yes — specifically formulated for inhalation |
| Typical strengths (UK) | 300mg–6,000mg per 30ml | 3,000mg–15,000mg per 60–100ml |
| Best suited for | Long-lasting daily wellness support | Fast-acting relief — stress, anxiety, sleep |
How Does Vaping CBD Work in the Body?
When you inhale CBD vape juice, the vapour passes through your airways into the lungs, where CBD molecules cross the thin alveolar membrane directly into the bloodstream. From there, CBD interacts with the endocannabinoid system a network of receptors distributed throughout the brain and body that plays a role in regulating mood, sleep, pain perception, and inflammation.
Because inhalation bypasses what pharmacologists call first-pass metabolism the process by which the liver breaks down a large proportion of oral compounds before they reach circulation — a substantially greater amount of CBD reaches the bloodstream compared to swallowing it. This is why vaping is consistently described as the most bioavailable method of CBD consumption currently available in the UK.
It is also worth noting that the effects of CBD vary between individuals based on body weight, metabolism, prior CBD use, and the specific reason for using it. If you are using CBD specifically for anxiety relief, our dedicated CBD anxiety pen guide covers dosing and product selection in more detail.
What Strength CBD Oil Vape Should I Use?
Choosing the right strength is probably the question most first-time buyers get wrong. The instinct is often to start strong, but with CBD the opposite approach is sensible start lower than you think you need, assess the effect, and increase gradually. The strength guide table below covers the full Haze CBD range from beginner through to advanced use.
The Food Standards Agency advises healthy adults not to exceed 70mg of CBD per day from all sources combined. For reference, a 3,500mg per 100ml vape juice contains approximately 35mg of CBD per 10ml vaped. Starting with 3–5 puffs and waiting 10 minutes before taking more is a reliable method for calibrating your dose without overshooting.
| Strength | Best For | Typical User | Haze Product |
|---|---|---|---|
| 150mg | Very mild, introductory use | First-time CBD vapers wanting a low-commitment starting point | Haze Bijou Disposable (150mg) |
| 300mg | Mild daily use, light stress relief | Occasional vapers or those sensitive to CBD | Haze 150 Disposable range |
| 3,000–3,500mg | Regular use, moderate effects | Experienced vapers using CBD for daily wellness, sleep or anxiety | Haze Strains 60ml / Haze Rock 100ml |
| 15,000mg | High-strength daily use | Experienced users managing chronic conditions requiring consistent high-dose CBD | Haze Diamond 100ml |

Frequently Asked Questions
What is the difference between CBD oil and CBD vape oil?
CBD oil is an oral tincture designed to be placed under the tongue it uses plant-based carrier oils such as MCT or hemp seed oil. CBD vape oil (also called CBD e-liquid or CBD vape juice) is formulated with a PG/VG carrier base specifically for use in vaping devices. These are not interchangeable. Never put oral CBD oil in a vape device.
How much CBD vape oil should I use per day?
The FSA advises healthy adults to take no more than 70mg of CBD per day from all sources. For a 3,500mg per 100ml vape juice, each 1ml contains approximately 35mg of CBD. Start with 3–5 puffs, wait 10 minutes, and adjust from there.
Can CBD oil vape make you high?
No. CBD is non-psychoactive. All legal CBD vape products in the UK contain less than 0.2% THC far below any threshold for psychoactive effect. You will feel calm and relaxed, not impaired or intoxicated.
How long does a 100ml bottle of CBD vape oil last?
A 100ml bottle typically delivers 10,000–15,000 puffs depending on your device and draw length. For a moderate user taking 30 puffs per day, a 100ml bottle generally lasts between 3 and 5 months.
What devices work with CBD vape oil?
Most standard pod systems and refillable vape kits are compatible with CBD vape juice. We recommend the OXVA Xlim Pod Kit (5–25W), Argus X Pod Kit (5–18W), and Nevox Feelin A1 Pod Kit (10–30W). Avoid sub-ohm devices running at very high wattage, as these can degrade the CBD and produce harsh vapour
