How to Make Weed Gummies at Home: Decarb, Infuse and Dose (2026)

By James Buddsey · Updated October 16, 2026

To make weed gummies at home, you activate the THC in cannabis by baking it (decarboxylation), infuse it into a fat such as coconut oil, then whisk that oil into a warm gelatin or pectin mixture and pour it into molds. The cooking is easy. The hard part is dosing, because homemade gummies have no lab label, so you have to estimate the strength, keep servings small and store them where children cannot reach them.

This guide compares the two practical home methods, the classic flower-to-oil route and the shortcut that starts with a lab-labeled product from a licensed store, then walks through the math that keeps a batch from turning into a bad night. It covers solvent-free kitchen methods only.

Homemade Gummies at a Glance

Step 1: Decarboxylate the Flower

Raw cannabis contains mostly THCA, which does not produce much of a high. Heat converts it into THC. That is why eating raw bud does little, and why every flower-based edible starts in the oven. Our cannabutter guide explains the chemistry in more detail.

1. Heat the oven to about 240°F to 250°F. Oven dials are often off by 25 degrees, so an oven thermometer helps.
2. Break the flower into small pieces or grind it coarsely. A fine powder is harder to strain later.
3. Spread it in a single layer on a parchment-lined baking sheet, or seal it in an oven bag to contain the smell.
4. Bake 40 to 50 minutes, until it turns light golden brown and dry. Darker brown means you are burning off THC.

These times and temperatures come from informal guides and grower practice, not controlled studies, so treat them as a starting point.

Step 2: Infuse the Oil

THC dissolves in fat, not water, so gummies need an oil infusion. Coconut oil and MCT oil are popular because they are high in saturated fat and stay liquid enough to mix.

1. Combine the decarboxylated flower with the oil in a slow cooker on low, a double boiler, or a small saucepan over the lowest heat. Many cooks use about 7 to 10 grams of flower per cup of oil; for gummies, a smaller batch (for example 1 to 3 grams in a quarter cup) is easier to dose.
2. Keep the oil around 160°F to 190°F for 2 to 3 hours, stirring now and then. Do not let it smoke or boil.
3. Strain through cheesecloth or a fine mesh strainer. Press gently; squeezing hard pushes bitter plant material through.
4. Label the jar with the date, the strain and your estimated potency (see the math below).

Skip anything involving butane, propane or other solvents. They create fire and explosion hazards, and Washington’s RCW 69.50.450 reserves extraction with explosive gases for licensed processors. Oil infusion needs no solvent.

Step 3: Make the Gummy Mix

A typical gelatin batch for one or two silicone molds:

• 1/2 cup fruit juice (or water)
• 1 small box (3 oz) flavored gelatin dessert mix
• 2 to 3 tablespoons unflavored gelatin
• 1 teaspoon sunflower or soy lecithin (helps the oil stay mixed instead of floating)
• Your measured infused oil, or a measured amount of tincture or distillate

1. Warm the juice in a saucepan over low heat. Whisk in the flavored and unflavored gelatin until fully dissolved. Keep it below a simmer.
2. Add the lecithin, then the infused oil, and whisk steadily for 2 to 3 minutes until the mix looks even and slightly cloudy.
3. Fill the molds with a dropper or a small measuring spoon. Stir the pot between fills, because oil separates as the mix sits and creates “hot” gummies.
4. Refrigerate 1 to 2 hours until set, then pop them out. Letting them air-dry on a rack for a day or two gives a firmer, chewier texture.

Vegan option: pectin replaces gelatin, but it needs sugar, acid (such as citric acid) and a full boil to set, so follow a tested pectin candy recipe and add the cannabis at the end, once the mix is off the heat.

The Labeled-Product Shortcut

If you live where adult-use sales are legal, the most accurate homemade gummy starts with a product that already carries a lab-tested THC number, such as a tincture or a distillate syringe. You skip decarboxylation and infusion and replace the infused oil in Step 3 with a measured amount of that product. Warm a distillate syringe in warm water first so it flows.

Premixed gummy kits work on the same idea: you add water and a measured amount of distillate or tincture to a packaged gelatin blend. They are convenient, but the dose is still only as accurate as your measuring and stirring. Our tinctures guide covers how labeled tinctures are dosed.

How Strong Are Your Gummies? The Math

Homemade potency can only be estimated. Start with the maximum:

Grams of flower × THC percentage × 10 = maximum mg of THC

Example: 1 gram of flower at 20% THC holds at most 200 mg. Divide by the number of gummies. Spread over 40 gummies, that is at most 5 mg each. Real gummies will be weaker, because decarboxylation and infusion are never complete, but the true loss is unknown without lab testing. Treat the maximum as your working number. That is the safe assumption.

For a labeled product, the math is direct: if you add 100 mg of THC to a batch of 20 gummies, each averages 5 mg, provided you stirred well.

For scale, Washington’s rules for store-bought edibles cap a serving at 10 mg of THC and a package at 100 mg. A single homemade gummy made from “an eighth in a cup of oil” can blow far past that.

Dosing and Safety

• Start with 2.5 to 5 mg of THC if you are new to edibles. This is common harm-reduction practice, not an official dose. See our cannabis dosage guide.
• Wait at least two hours before eating more. Edibles act slowly; the National Cancer Institute’s cannabis PDQ summary puts peak blood levels 1 to 6 hours after eating.
• Do not drive and do not mix with alcohol.
• Lock them up. Gummies look like candy. The CDC says edibles carry a greater risk of poisoning than smoked cannabis and that children who eat THC products can become very sick. NIDA’s cannabis research page also warns about delayed effects leading people to take too much.
• Label everything: “CANNABIS,” the date and the estimated mg per gummy. If a child or pet eats one, call Poison Help at 1-800-222-1222 or seek emergency care.

Storage

Keep homemade gummies in an airtight container in the refrigerator, away from other snacks. Gelatin gummies without preservatives can mold within a week or two at room temperature, so make small batches. Freezing extends life for longer storage. Infused oil keeps best in a dark, cool place in a sealed jar.

Is It Legal to Make Edibles at Home?

In Washington and Oregon, adults 21 and older can buy cannabis from licensed stores, and kitchen infusion uses no regulated solvent. You still cannot sell homemade edibles or give them to anyone under 21. Possession limits apply, so check our Washington and Oregon law guides. If you would rather buy lab-tested gummies, find a licensed store in our Washington or Oregon directory.
