The Short Answer
Home-cooked cannabis edibles let adults 21 and older make their own dose-controlled products at a fraction of dispensary prices. The two things that trip up first-time home cooks: incomplete decarboxylation (which leaves the cannabis non-intoxicating) and miscalculating dose per serving (which produces either weak edibles or the infamous 200 mg brownie experience).
Step 1: Decarboxylation
Raw cannabis contains THCA, which is non-intoxicating. Heat converts it to THC. For edibles, decarboxylation has to happen before the cannabis goes into the recipe:
Method: Preheat oven to 240°F (115°C). Spread cannabis flower on a parchment-lined sheet pan. Bake 30 to 40 minutes, stirring once. Flower should turn slightly darker green/brown. Let cool.
Step 2: Infuse a Fat
Cannabinoids are fat-soluble. Infuse them into butter or oil:
Cannabutter (basic recipe):
- 1 cup unsalted butter.
- 1 cup water (helps regulate temperature).
- 7 to 14 grams decarboxylated flower (dose-dependent).
- Combine in saucepan, simmer low heat for 2 to 3 hours, strain through cheesecloth.
Cannabis oil: Same method with olive oil, coconut oil, or MCT oil.
Step 3: Calculate Dose
This is where home edibles fail. Dose math:
- Start with the THC content of your flower (example: 20 percent THC).
- 7 grams flower × 200 mg/g = 1,400 mg raw THC.
- Decarb conversion (approximately 87 percent efficiency) = ~1,218 mg available.
- Infusion efficiency (typically 50 to 70 percent) = ~609 to 853 mg in the finished butter.
- Assume 600 mg to be conservative.
If that butter goes into a batch of 30 cookies: 600 mg / 30 = 20 mg THC per cookie. For beginner-friendly dosing, you'd want to split each cookie in half (10 mg per half).
Err low. Pros test a batch with a single small sample before committing.
Step 4: Simple Recipes
Cannabis brownies: Substitute cannabutter for regular butter in a standard brownie recipe.
Cannabis pasta sauce: Swap cannabis oil for regular olive oil in the finishing step of sauces (not during high-heat cooking, high temperatures can degrade cannabinoids).
Cannabis honey: Infuse cannabis into honey using a double-boiler method. Takes several hours but produces a neutral-tasting, versatile infusion.
Tinctures: Not technically cooking, but DIY tinctures made by soaking decarbed flower in high-proof alcohol for several weeks produce sublingual-ready products.
Dosing Tips
- Label everything with estimated dose per serving.
- Start with half your estimated dose on a first taste.
- Wait the full 90 to 120 minutes before taking more.
- Refrigerate or freeze leftovers, cannabinoids degrade at room temperature.
Things to Avoid
- High heat. Above 320°F (160°C), THC begins degrading quickly.
- Butter at boiling. Simmer, don't boil. Boiling degrades cannabinoids.
- Uneven distribution. Mix infused butter/oil thoroughly into the recipe.
- Underestimating onset. 90 to 120 minutes for homemade edibles. Don't redose at 45 minutes.
Compliance
- 21+ only.
- Secure storage. Edibles that look like standard food products are a pediatric-poisoning risk.
- Label clearly. "Cannabis cookies - 10 mg each" on the container.
- No serving to non-consenting adults. Ever.
