How to make THC vape oil?
The promise of DIY cannabis oil is tempting—but do you know what it really takes?
You can make THC vape oil at home by extracting cannabinoids from cannabis, refining it into a distillate or resin, and then mixing it with compatible thinning agents for use in vape hardware.
Some people want to save money. Others want to control what they inhale. Either way, homemade THC vape oil sounds simple. But it's not as easy as squeezing juice from fruit. Getting it right means knowing how the process works and using the right tools.
What kind of oil is used in THC vapes?
This question sounds simple, but the answer is more layered than most people think.
THC vapes use oils like THC distillate, live resin, and live rosin—each with different effects, thickness, and purity levels suited for cannabis vape hardware.

There are different kinds of THC oils used in vapes. Each one needs a slightly different cartridge design, especially when it comes to heating and wicking. Here's a deeper breakdown to help you understand the key types:
Common Types of THC Vape Oils
| Oil Type | Description | Thickness | Terpene Content | Common Use |
|---|---|---|---|---|
| THC Distillate | Highly refined, nearly pure THC | Very thick | Low | Everyday vaping |
| Live Resin | Extracted from fresh frozen cannabis | Thick | High | Flavor-rich vaping |
| Live Rosin | Solventless extraction from fresh frozen | Thickest | Very High | Premium, terp-rich vaping |
These oils can’t just go into any device. They need a proper cartridge that’s made for thick oils. The heating core must be strong enough to vaporize the dense concentrate. If not, you’ll get clogging, bad flavor, or worse, nothing at all.
Can I fill my vape with THC oil?
You might think, “Why not just refill the vape I already have?” Here's why that could be a mistake.
Yes, but only if your vape device is designed for THC oil. Nicotine vapes usually can't handle the thickness of THC oils and may clog or burn out.
Not all vapes are the same. This is where many users go wrong. I’ve seen friends pour THC oil into a pod made for nicotine. At best, they got a burnt hit. At worst, they wasted all their oil.
Vape Compatibility Breakdown
| Vape Type | Designed For | Can Use THC Oil? | Risk if Used with THC Oil |
|---|---|---|---|
| Nicotine Vape | Thin e-liquids | ❌ No | Clogging, burning, leaking |
| THC Cartridge Vape | Thick concentrates | ✅ Yes | None, if quality is good |
| Hybrid Vape | Swappable cores | ✅ Conditional | Depends on cartridge design |
THC oil is sticky. It doesn’t flow like e-liquid. Nicotine vapes often use cotton-based wicks that can’t soak up THC oil fast enough. This causes dry hits and damages the coil. THC-specific vapes use ceramic or special metal cores to handle thicker oils and higher heat levels. Always check the specs before filling.
What is the difference between live resin and THC oil?
It’s easy to mix up live resin and THC oil—but they’re not the same thing.
Live resin is a type of THC oil made from fresh frozen cannabis, while generic THC oil often refers to distillate or oil from dried plants.
Live resin and THC oil serve different purposes. I remember trying a live resin cart for the first time—it tasted like I had just taken a hit off a fresh flower. The flavor was unreal compared to the flat taste of distillate carts.
Key Differences: Live Resin vs THC Oil
| Feature | Live Resin | THC Distillate/Oil |
|---|---|---|
| Source Material | Fresh frozen cannabis | Dried and cured cannabis |
| Flavor Profile | Strong, terpene-rich flavor | Mild to neutral |
| Potency | Moderate to high | Very high (up to 95% THC) |
| Extraction | BHO or solvent-based | Fractional distillation |
| Use Case | Terp lovers, full effect | High potency, easy mixing |
Live resin keeps most of the original plant's aroma and cannabinoids. It feels more like the whole-plant experience. Distillate is stripped down—pure THC, but without much taste or entourage effect. Brands choose one over the other based on what their customers want: flavor or strength.
