The Basics: What Is THC Oil?

THC oil, sometimes called THC liquid or THC vape juice, is a concentrated form of cannabis designed for use in vape cartridges, vapor cups, 510-thread Batteries. It’s made by extracting the active compounds (THC and terpenes) from cannabis buds or concentrates, then blending them with a carrier liquid like vegetable glycerin or propylene glycol.

This process produces a smooth, vapor-ready oil that can be loaded into refillable THC carts or 510 cartridges. For anyone wondering how to make THC oil at home, the process is simple, but it requires attention to detail and quality ingredients.

These terms are often used interchangeably, but here’s the quick breakdown:

THC Oil is the pure cannabis extract. It’s thick, sticky, and potent.
THC Liquid is THC oil that’s been thinned with a carrier so it can be vaporized.
THC Vape Juice is the final mixture that’s ready to load into a vape pen or 510 cartridge.

If your goal is to make THC oil for vaporizer use, you’ll want to follow the extraction and blending process carefully.

Making THC oil at home can be done using simple tools and ingredients. You’ll need:

Raw cannabis buds or concentrates

High-proof grain alcohol (not rubbing alcohol)

Vegetable glycerin or propylene glycol (food-grade)

A glass jar, baking tray, thermometer, and cheesecloth

Step 1: Decarboxylate the Cannabis

The first step is to activate the THC in your cannabis. Break your buds apart, spread them on parchment paper, and bake them at 230°F (110°C) for 35–45 minutes. This process, called decarboxylation, converts THCA into THC, unlocking the psychoactive effects.

Step 2: Extract the THC

Place your decarbed buds in a clean glass jar and pour in enough high-proof alcohol to fully cover them. Gently stir, then refrigerate for 20–30 minutes. Strain the mixture through cheesecloth into another jar to remove the plant matter.

Step 3: Purify the Oil

Set the jar containing your alcohol extract in a pot of warm water (around 160°F or 71°C). Let the alcohol slowly evaporate. What remains will be your concentrated THC oil, dark, sticky, and potent.

Step 4: Create Your THC Liquid

To make your oil vaporizer-ready, mix the concentrated extract with vegetable glycerin or polyethylene glycol (PEG). Start with about one milliliter of carrier liquid for every gram of THC extract. Shake well to blend until smooth. You now have THC liquid that can be filled into a cartridge or tank.

If you prefer a faster, cleaner method, use a Wax Liquidizer. It’s a pre-made solution designed to turn shatter, wax, or crumble into THC vape oil in minutes.

Add your concentrate, pour in the Wax Liquidizer, gently warm, and stir. Within minutes, you’ll have perfectly thinned THC liquid ready to fill your 510 cartridge.

You can find the Wax Liquidizer at Canadian Vaporizers. It’s compatible with all standard 510 carts and eliminates the need for alcohol or long extraction steps.

Once your THC oil or THC liquid is ready, you’ll need the right device. The most common setup is a 510 cartridge paired with a 510 thread battery, a universal system that fits most THC carts in Canada.

For reliable performance, explore our 510 Thread Battery Collection. These batteries power your cartridge efficiently and allow temperature control for optimal vaporization.

If you prefer something more powerful, a desktop vaporizer or electric dab rigs can also handle THC oil with excellent flavor and cloud production.

Always use food-grade ingredients and high-proof grain alcohol, not rubbing alcohol.
Work in a well-ventilated area when heating your extract.
Avoid open flames near alcohol or solvents.
Store your THC oil in glass containers, away from sunlight.

If you’re unsure about making it yourself, stick with store-bought THC cartridges and vaporizers for consistent results and verified quality.
