How to Make THC Vape Juice at Home: A Step-by-Step DIY Guide
Safety first: if you make your own vape liquid, use only pharmaceutical or vape-grade propylene glycol (PG) and vegetable glycerin (VG) and flavorings clearly labeled as safe to inhale. Never add cooking or carrier oils (MCT, coconut, olive) or vitamin E acetate to a vaping liquid: oils are for eating, not for inhaling, and vitamin E acetate has been linked to serious lung injury (EVALI). Start with a very low dose, and check that home-producing cannabis products is legal where you live.
THC vape juice (also called cannabis e juice) is a discreet, convenient way to consume cannabis. If you want to learn how to make THC vape juice at home, this guide walks you through it step by step: decarboxylating your flower, infusing it into a PG/VG base, dosing it safely and turning it into a high-quality vape liquid, plus a few DIY recipes to try.
Recommended Strains
Making your own vape liquid lets you control the potency, flavor and strain, whether you want a mild or a strong formula. It is a way to enjoy cannabis without smoking it. Let’s get into how to make THC vape juice.
Ingredients and Equipment You Need
Before you start, gather everything you need. Most of these items are inexpensive and easy to find, but the two you should never improvise on are the PG/VG base and any flavoring, which must be vape-grade and safe to inhale. Here is the full list:
- Cannabis: high-quality, dried and cured flower. Strains from Blimburn Seeds like Wombat, Critical Daddy Purple and BC Diesel work well.
- Propylene glycol (PG) and vegetable glycerin (VG): vape-grade only, the base of your e juice. Buy from a vape shop, not the kitchen.
- A grinder: to break the flower down to a fine, even consistency.
- An oven and baking sheet: for decarboxylation.
- A glass jar and cheesecloth: for infusing and then straining the mixture.
- A dropper bottle: to store and dispense the finished liquid.
- Food-grade flavoring (optional): only extracts labeled safe to inhale.
The quality of your finished THC vape juice depends heavily on your starting material: the better the flower, the better the taste, aroma and potency of the e-liquid. Use the best cannabis you can afford.

How to Make THC Vape Juice: Step by Step
The first step in making cannabis e juice is to decarboxylate your cannabis. This process involves heating your cannabis to activate the THC and other cannabinoids. Here’s how to do it:
- Preheat your oven to 240°F (115°C).
- Grind the cannabis until it is a fine, even powder.
- Spread it in a thin, even layer on a baking sheet.
- Bake for 30-40 minutes, stirring every 10 minutes so it heats evenly. This activates the THC (decarboxylation); skip it and your vape juice will have little to no effect.
With your cannabis decarboxylated, the next step is infusing it into the PG/VG base. This is where the flavor and potency actually transfer into the liquid, so give it time.
- Combine the decarboxylated cannabis with your PG/VG in a glass jar. A good starting ratio is 1 gram of cannabis per 10 ml of PG/VG; use more for a stronger liquid, less for a milder one.
- Seal the jar and shake well.
- Let it infuse for at least two weeks, shaking once a day. The cannabinoids and terpenes need time to move into the PG/VG, so do not rush this step.
After two weeks the mixture is ready to strain. Do not rush the infusion: the cannabinoids and terpenes need the full time to move into the liquid, and that is what determines the final strength.
- Line a clean glass jar with cheesecloth and pour the mixture through it to strain out the plant material. Discard the spent cannabis.
- Use a dropper to transfer the finished liquid into a dropper bottle. Store it in a cool, dark place away from light and heat.
And that’s it: your own homemade THC vape juice, ready to use. Start with a small dose to see how it affects you. Next, a few DIY recipes to try.
DIY THC Vape Juice Recipes
Now that you know the basic method, you can experiment with different strains, terpene profiles, flavors and strengths. Here are three variations to get you started:
One safety rule overrides every recipe: never thin your juice with vitamin E acetate, cooking oils or other fillers. Those additives were linked to the serious EVALI lung-injury outbreak, and they have no place in anything you inhale. Stick to food-grade VG, PG or terpenes, and start with a lower THC strength than you think you need, since homemade juice can be surprisingly potent and is easy to over-do.
| Base | Typical ratio | How it feels |
|---|---|---|
| VG-heavy | 70 VG / 30 PG | Thick clouds, smoother, gentler throat hit |
| Balanced | 50 VG / 50 PG | Even clouds and flavor |
| PG-heavy | 30 VG / 70 PG | Stronger flavor and throat hit, thinner vapor |
| Terpene-thinned | Distillate plus terpenes | No VG or PG; the most natural cannabis flavor |
Simple THC Vape Juice
This is the basic recipe we just walked through and the best starting point for beginners. Follow the steps above with your chosen strain, keeping the 1 g per 10 ml ratio for a moderate strength.
If you’re new to making your own blends, it’s important to start slowly and gradually increase the amount you use. This will help you find the strength that’s right for you. Keep in mind that it’s always easier to add more than to reduce potency. Start with a small amount and adjust gradually until you reach the perfect balance for your needs.
Flavored THC Vape Juice
To add flavor, customize your THC vape juice recipe with extracts that are labeled safe to inhale. Popular options include vanilla, mint and fruit flavors. Add a few drops to the infused PG/VG before straining so the flavor blends evenly.
Only use flavorings clearly labeled as safe to inhale: many food-grade extracts are meant for eating, not vaping. As always, start with a couple of drops and adjust: you can add more, but you can’t remove it once mixed.
CBD-Infused Vape Juice
If you prefer CBD to THC, make CBD-infused vape juice using the same method with a CBD-rich strain from Blimburn Seeds. You will get the same process, without the strong psychoactive effect.
Many people choose CBD-infused juice because it is non-intoxicating, so you get the character of the plant without feeling high. Making it yourself lets you control the strength and flavor, just as with the THC version.
Whether you go for THC or CBD, making your own vape juice lets you control the strain, strength and flavor. Just do it responsibly: use inhalation-safe ingredients, start low and follow your local laws.
FAQs About Making THC Vape Juice
Is it legal to make THC vape juice at home?
It depends entirely on where you live. In some places making THC vape juice for personal use is legal; in many it is not, and selling homemade cannabis products without a license is almost always illegal. Cannabis laws change often, so check your current local and state regulations before you make any.
How can I make my THC vape juice stronger?
To make your THC vape juice stronger, use more cannabis than the standard 1 gram per 10 ml of PG/VG, or choose a higher-THC strain. A stronger liquid means you need less per session, so dose carefully and go slow, especially with high-THC flower.
How should I store my THC vape juice?
Store your THC vape juice in a sealed dropper bottle in a cool, dark place, away from light, heat and air, which all degrade cannabinoids over time. Kept this way it can last several months, but for the best flavor and potency use it within a few weeks of making it.
Can I use fresh cannabis to make vape juice?
It is not recommended. Fresh cannabis contains THCA, which is non-psychoactive until it is heated and converted to THC through decarboxylation. Use dried, cured flower and decarb it first, otherwise your THC vape juice will have little to no effect. The better the flower, the better the result.
Can I use CBD oil to make vape juice?
Be careful: not all CBD oils are made for vaping. Only use a CBD e-liquid or CBD-rich flower infused into vape-grade PG/VG; never vape an oral CBD oil in a carrier oil, as oils are not safe to inhale. For a full-spectrum result, infuse a CBD-rich strain the same way as THC vape juice.
