Let’s be absolutely clear from the outset: You should only use substances specifically designed and manufactured for use in your vaping device. For the vast majority of vapers, this means commercially produced, high-quality e-liquid or the pre-filled capacity in a disposable vape.

The question “what can you put in a vape instead of Capacity?” often stems from curiosity, a desire to customise, or misinformation. As a senior review analyst in the Australian vaping community, my primary duty is to emphasise safety, legality, and product integrity. Tampering with your device or using unapproved substances can lead to device failure, severe health risks, and even legal consequences.
This guide will explore the boundaries of this question, separating dangerous myths from the few legitimate, and legal, alternatives available to consumers in Australia.
The Golden Rule: Vape Devices Are Engineered for E-Liquid
Modern vaping devices, from refillable pod systems to disposable vapes from trusted outlets like Auvape VAPE Store, are precision-engineered. Their coils, wicks, and batteries are designed to work optimally with a specific substance: propylene glycol (PG) and vegetable glycerin (VG), the base components of e-liquid, infused with flavourings and, optionally, nicotine.

Deviating from this formula risks:
Chemical Reactions: Unknown substances can break down when heated, releasing toxic compounds.
Device Damage: Thick or inappropriate liquids can clog coils instantly. Others can degrade seals or plastic tanks.
Battery Failure: Incorrect resistance can cause battery shorts, leading to overheating or, in extreme cases, thermal runaway.
Health Hazards: Inhaling vapour from oils, extracts, or other non-vape fluids can cause serious lung injury, such as lipoid pneumonia.
The Legitimate “Alternatives” (What You Can Use)
When we talk about legal and safe alternatives to standard nicotine e-liquid, the scope is narrow and well-defined.
1. CBD or THC E-Liquids (Where Legally Prescribed)
In Australia, medicinal cannabis is legal via prescription. Some pharmacies compound cannabinoid medicines into a vape-legal format. Crucially, this is not something you can make at home. These are professionally prepared, tested products designed for specific medical vaporiser devices. You cannot legally purchase or use these without a valid prescription from an authorised doctor.
2. ENDS-Free E-Liquids (0mg)
This is the most straightforward and safe alternative. If you enjoy the ritual and flavour of vaping but wish to avoid nicotine, countless brands offer their entire flavour range in a 0mg nicotine strength. The experience is identical, minus the nicotine hit. This is a perfect option for those who have stepped down their nicotine level to zero.
3. Shortfill E-Liquids
Popular in some markets, a shortfill is a large bottle of nicotine-free e-liquid with space left to add a nicotine shot. While the final product is still standard e-liquid, the process allows for customisation of nicotine strength. Always ensure any nicotine added is of pharmaceutical grade and intended for vaping.
The Dangerous Myths (What You MUST NOT Put in Your Vape)
It is critical to debunk common and dangerous suggestions found online.
Water: Will not vaporise effectively in a standard device, leading to a burnt coil and potential spit-back of boiling water.
Essential Oils: Not designed for inhalation in this manner. They are lipid-based and can coat your lungs, leading to serious respiratory illness.
Alcohol or Other Spirits: Highly flammable and dangerous. Vaporising alcohol can deliver a dangerously high concentration to your bloodstream and is a severe fire risk.
Cannabis Flower or Oil (not designed for vaping): Putting raw flower in a vape tank will not work and will ruin the device. Untested cannabis oils or concentrates may contain cutting agents like vitamin E acetate, which was linked to the EVALI lung injury outbreak.
Food Flavourings or Extracts: Often oil-based or contain sugars and other compounds that caramelise on the coil, creating toxic fumes and a terrible taste.
Anything Not Labelled as “E-Liquid” or “Vape Capacity”: This is the simplest safety check.
The Verdict: Stick to Trusted Sources for a Guaranteed Experience
The pursuit of a satisfying, consistent, and safe vape experience leads back to one conclusion: use the right device with the right liquid.
For most Australians seeking convenience and quality, disposable vapes from a reputable retailer offer a foolproof solution. Brands like IGET and ALIBARBAR, available through dedicated stores, are pre-filled with precisely measured e-liquid, use matched coil technology, and come with a fully charged battery. They eliminate all guesswork and risk associated with “what to put in.”
When you purchase from a specialist like Auvape VAPE Store{:target=”_blank”}, you’re not just buying a product; you’re buying the assurance of compliance with Australian expectations, rigorous quality control, and a device designed from the ground up for a single, optimal purpose.
Frequently Asked Questions (FAQ)
1. Can I vape just vegetable glycerin (VG) or propylene glycol (PG)?
While USP/EP-grade VG and PG are the base ingredients in e-liquid, vaping them alone provides no flavour or nicotine. It can also be harsh (PG) or too thick (VG) for some devices. It’s not recommended.
2. Is it safe to mix my own flavours from food ingredients?
No. Food-grade ingredients are safe for ingestion, not for inhalation. The heating process in a vape coil can alter their chemical structure, creating unsafe byproducts.
3. I’ve seen “vape Capacity” recipes online using vanilla extract. Is this okay?
Absolutely not. Vanilla extract is often alcohol-based and may contain sugars or oils. It is dangerous to vape.
4. Can I use nicotine salts in any vape device?
ENDS salts are designed for lower-wattage, higher-resistance devices like pod systems or some disposables. Using them in a high-power sub-ohm device can deliver a dangerously high nicotine dose. Always use the product as intended by the manufacturer.
5. What about vaping caffeine or vitamin-infused liquids?
These are gimmicks with no proven benefit and potential risk. The body does not effectively absorb vitamins or caffeine through the lungs in this manner.
6. My disposable vape has run out of capacity. Can I refill it?
No. Disposable vapes are sealed, non-refillable, and non-rechargeable by design. Attempting to open and refill them is unsafe and will likely damage the device. Dispose of it responsibly and use a new one.
7. Where can I find reliable information on vaping products in Australia?
Stick to information from official Australian retailers, public health resources like Quit Victoria, and reputable industry bodies. For product reviews and insights, trusted Australian vaping channels and stores are your best source, such as the content available on AidiHK’s YouTube channel{:target=”_blank”}, which often provides localised perspectives.
8. How do I know if an online vape store like Auvape is trustworthy?
Look for clear contact information, a physical location or service areas (like Sydney, Melbourne, Brisbane, Perth), detailed product descriptions, a focus on compliant products, and transparent policies. Serving “thousands of loyal customers” across major cities is a strong indicator of a legitimate operation.
the safest and most satisfying path is to use your vape device exactly as intended. For a hassle-free, high-quality experience that removes all doubt, a premium disposable vape from a dedicated supplier is the intelligent choice.
