What is vaping? It is a question more Canadian vapers are asking as vaping becomes one of the most common alternatives to smoking across the country. Whether you are a smoker curious about switching, someone who has tried a disposable and wants to understand more, or simply looking for clear answers without jargon, this guide covers everything you need to know.
Vaping is not complicated once you understand the basics. This guide breaks down how it works, what devices exist, what goes into vape juice, and how vaping differs from smoking.
What Is Vaping and How Does It Work
Vaping is the act of inhaling vapour produced by a battery-powered device. The device heats a liquid, commonly called "vape juice" or "e-liquid", until it becomes a vapour that you inhale. No combustion happens. No tobacco burns. No smoke is produced.
The core components of any vaping device are a battery, a heating element called a coil, and a chamber that holds the e-liquid. When you activate the device, the battery powers the coil, which heats the liquid rapidly and converts it into vapour. You inhale that vapour and exhale it.
That process is what separates vaping from smoking. Smoking burns tobacco, producing smoke that contains thousands of chemical compounds from combustion. Vaping heats a liquid to produce vapour, which is a fundamentally different process with a different composition.
What Is Vaping Made Of
Understanding what vaping is made of starts with the e-liquid. Most vape juice contains four core ingredients.
Propylene Glycol
Propylene glycol, commonly called PG, is a thin, colourless liquid used widely in food and pharmaceutical products. In vape juice, PG carries flavour well and produces a throat hit that many smokers find familiar when switching from cigarettes. Higher PG liquids tend to produce less visible vapour.
Vegetable Glycerin
Vegetable glycerin, or VG, is a thicker, slightly sweet liquid derived from plant oils. It is responsible for producing the visible vapour clouds associated with vaping. Most e-liquids use a combination of PG and VG to balance throat feel, flavour, and vapour production.
Nicotine
Not all vape juice contains nicotine, but most products designed for smokers switching to vaping do. Nicotine in vape juice comes in two main forms: nicotine salts and freebase nicotine. The section below on vape juice explains the difference in more detail.
Flavourings
Food-grade flavourings are added to create the wide range of fruit, menthol, tobacco, and dessert profiles available in Canadian vape juice. These are the same types of flavourings used in food production, though their long-term inhalation effects continue to be studied.
Types of Vapes
The Canadian vaping market has several distinct device categories. Knowing which type suits you is one of the first practical decisions any new vaper needs to make.
Disposable Vapes
Disposable vapes are single-use devices that come pre-filled with e-liquid and a pre-charged battery. You use the device until the liquid or battery runs out, then discard it. They require no setup, no filling, and no maintenance.
Disposables are the most popular starting point for vapers new to vaping in Canada. Brands like Geek Bar, STLTH, Flavour Beast, Mr. Fog, and Drip'n produce disposables across a wide range of flavours and puff counts. Puff capacities range from a few hundred to tens of thousands of puffs depending on the device.
They are the most convenient entry point into vaping, though they tend to cost more per puff over time compared to refillable setups.
Pod Systems
Pod systems use a small device paired with either pre-filled pods or refillable pods you fill yourself. The device is reusable, and you replace or refill the pod when it runs out. Pod systems from brands like Vaporesso, Uwell Caliburn, and STLTH are popular across Canada for daily vapers.
Pre-filled pods offer the same convenience as disposables without replacing the entire device each time. Refillable pods give you more flexibility over which e-liquid you use and tend to be the most cost-effective setup for regular vapers.
Vape Mods and Advanced Devices
Vape mods are larger, more powerful devices that offer adjustable settings including wattage and airflow. They are typically used by experienced vapers who want more control over their vaping experience. Sub-ohm tanks and rebuildable atomizers fall into this category.
Most smokers switching to vaping start with disposables or pod systems rather than mods. Mods have a steeper learning curve and require more knowledge about coil resistance, battery safety, and device settings.
Starter Kits
Starter kits are bundled packages designed for new vapers. They include a compatible device and pod or tank so you have everything needed to start without sourcing components separately. They are a practical choice for anyone who wants a refillable setup without the confusion of building a kit from scratch.
What Is Vape Juice Made Of and What Are Nic Salts
When people ask what is vaping liquid or what is vaping juice, the answer almost always starts with e-liquid composition. But there is an important distinction within nicotine-containing e-liquids that every new vaper in Canada should understand.
Nicotine Salts
Nicotine salts, often called "nic salts," are a form of nicotine that is smoother at higher strengths than freebase nicotine. They absorb into the body more quickly and produce a stronger nicotine hit without the harsh throat sensation that comes from freebase nicotine at the same strength.
Nic salts are the dominant form of nicotine in disposable vapes and pre-filled pods across Canada. They are typically available in strengths of 20mg or 50mg per millilitre, which translates well for smokers accustomed to the nicotine delivery of regular cigarettes.
What Is Freebase Vape Juice
Freebase nicotine is the original form of nicotine used in e-liquids. It is harsher at higher strengths but delivers a noticeable throat hit that some vapers prefer. Freebase e-liquid is more common in bottles designed for sub-ohm setups, typically at lower nicotine strengths ranging from 3mg to 12mg per millilitre.
The primary practical difference for a new vaper in Canada is this: if you are switching from cigarettes and want something that feels satisfying at a reasonable puff count, nic salt devices are generally the more appropriate starting point. Freebase liquids suit vapers who have already reduced their nicotine intake and prefer more vapour production with lower nicotine concentration.
What Is Vaping vs Smoking
The question of vaping vs smoking comes up constantly for Canadians considering a switch. There are meaningful differences worth understanding.
Smoking involves combustion. Tobacco burns at high temperatures, producing smoke that contains carbon monoxide, tar, and thousands of chemical compounds generated by that combustion process. Many of those compounds are established carcinogens.
Vaping does not involve combustion. The heating element in a vape device reaches temperatures that vaporize the liquid without burning it. The vapour inhaled contains far fewer compounds than cigarette smoke, and the compounds that are present generally exist at lower concentrations.
Health Canada acknowledges that while vaping is not risk-free, it is generally considered less harmful than smoking for vapers who switch completely. The key word is completely. Using both cigarettes and vaping products simultaneously reduces the potential benefits of switching.

What Is Vaping Addiction
Nicotine is an addictive substance, and most vaping products contain nicotine. That means the question of what vaping addiction is is a real and relevant one for any vaper considering starting.
Nicotine addiction develops through repeated exposure. The speed at which nicotine reaches the brain affects how reinforcing the behaviour becomes. Nic salts, because they absorb quickly, can create a stronger reinforcement pattern than slower-absorbing delivery methods.
For smokers who are already nicotine-dependent and switching from cigarettes to vaping, this dynamic is already present. For Vapers who have never smoked and are considering vaping, the risk of developing nicotine dependence through vaping is a genuine consideration worth taking seriously.
The goal for most smokers who switch to vaping is to reduce harm from combustion, not to add a new dependency. If you are using vaping to step down nicotine intake over time, choosing lower-strength e-liquids and gradually reducing nicotine level is a practical approach many smokers use.
What Is Vaping Regulation in Canada
Canada regulates vaping products under the Tobacco and Vaping Products Act. This legislation sets requirements for product labelling, nicotine concentration limits, and restrictions on promotion and packaging. All legal vaping products sold by Canadian retailers must comply with these standards.
As a consumer, buying from a verified Canadian retailer means the products you receive have been sourced through legitimate supply chains and meet Health Canada's regulatory requirements. Unlicensed or grey market vaping products do not carry the same assurances.
Quality Vapes is a Canadian online retailer with physical stores in London, Ontario. Every product in the catalogue is sourced from verified Canadian brands that operate within the country's regulatory framework.

Frequently Asked Questions
What is vaping in simple terms for someone who has never tried it?
Vaping is inhaling vapour from a battery-powered device that heats a liquid. The liquid typically contains nicotine, propylene glycol, vegetable glycerin, and flavourings. No tobacco burns and no smoke is produced. Most Canadian vapers use disposable devices or pod systems as their starting point.
What is vaping and how does it work mechanically inside the device?
A vaping device contains a battery, a coil, and a chamber for liquid. The battery powers the coil, which heats the liquid until it vaporizes. You inhale the vapour through a mouthpiece. The whole process takes less than a second from activation to inhalation, and no combustion occurs at any point.
What is vaping made of in terms of vape juice ingredients?
Most Canadian vape juice contains propylene glycol, vegetable glycerin, flavourings, and nicotine in either salt or freebase form. The ratios vary by product and brand. Nicotine-free e-liquids also exist and contain the same base ingredients without any nicotine added to the formula.
What is vaping vs smoking in terms of what enters your body?
Smoking produces combustion smoke containing thousands of compounds, including tar and carbon monoxide. Vaping produces vapour from heated liquid, which contains far fewer compounds. Health Canada notes that vaping is generally considered less harmful than smoking for smokers who switch completely, though vaping is not without its own risks.
What types of vapes are available for Canadians just starting out?
Canadians new to vaping typically choose between disposable vapes and pod systems. Disposables like Geek Bar, STLTH, and Flavour Beast require no setup. Pod systems from brands like Vaporesso and Uwell Caliburn are refillable and more cost-effective over time. Starter kits offer a complete refillable setup in one package for those ready to move beyond disposables.
