"Canna Lean" - CBD or THC Syrup

"Canna Lean" Recipe: How to Make CBD or THC Syrup at Home

By Mellow Moose | Updated 08/24/2026

Quick Answer

Canna lean is a cannabis-infused simple syrup built as a true emulsion — cannabinoids dissolved in a small oil phase, then emulsified into sugar syrup with lecithin so it blends smoothly into any drink. Using 2g of CBD or CBG isolate (or 1.2g of a THC source), one batch fills ~10–11 one-ounce dropper bottles at ~180mg CBD/CBG per ounce (~6mg/mL) or ~95mg THC per ounce (~3.2mg/mL). Total time is about 50 minutes.

Why This Syrup Recipe Actually Works in Drinks

Most homemade "THC syrup" recipes just stir extract into hot sugar water — and then the oil separates, floats, and delivers the whole dose in one unlucky sip. This recipe is a real emulsion, the same approach commercial beverage makers use:

• The oil phase (MCT) dissolves the cannabinoid completely — cannabinoids are fat-soluble, so this is where they actually go into solution.
• Lecithin + polysorbate 20 + glycerin are the emulsifier team: they wrap the oil in microscopic droplets that stay evenly distributed through the water-based syrup instead of separating out.
• The immersion blender shears those droplets small enough to keep the emulsion stable in the fridge and uniform in your glass.

The result: every milliliter carries the same dose, it mixes into cold drinks without clumping, and a batch costs a fraction of commercial cannabinoid syrups. Bonus, as many people report: drink-based infusions often feel like they come on a bit quicker than baked edibles — plan for standard edible timing anyway (more below).

Recipe Overview

• Yield: ~10–11 × 1 oz (30mL) bottles
• Prep time: 20 minutes
• Cook time: 30 minutes
• Difficulty: Intermediate

Equipment

• Immersion blender
• 1 oz dropper bottles (for storage and dosing)
• Cooking pot
• Mixing bowls
• Measuring cups & spoons
• Kitchen scale that reads to 0.1g

Ingredients

• 2g CBD Isolate or 2g CBG Isolate — or, for the THC version, 1.2g of a THC source: THCa isolate (decarbed first), THC distillate, or another dabbable extract (see the THC section below)
• 1.5 cups sugar
• 1 cup water
• 5mL (1 tsp) lecithin powder
• 1mL polysorbate 20
• 1mL vegetable glycerin
• 10mL MCT coconut oil
• 60mL corn syrup
• Food coloring (optional)
• Flavoring concentrate of choice
• Torani flavored syrup (optional, for dilution and taste adjustment)

Instructions

1. Prepare the oil mixture. In a small pot, gently heat the MCT oil. Dissolve the isolate (or your already-active THC source) into the oil, stirring until evenly blended and clear.
2. Combine with sugar. Transfer the oil mixture to a mixing bowl. Add the sugar and stir until fully coated. Set aside.
3. Make the lecithin mixture. In a separate bowl, combine lecithin powder, water, polysorbate 20, and vegetable glycerin. Stir vigorously for ~5 minutes.
4. Heat and blend. Pour the lecithin mixture into the pot with the sugar mixture. Heat on low — do not boil. Use the immersion blender to mix until smooth.
5. Incorporate corn syrup. Add the corn syrup and blend again for ~30 seconds.
6. Flavor & color. Add food coloring and flavoring concentrate as desired. Blend another 10–30 seconds. Optional but recommended: dilute the finished syrup 1:1 with Torani flavored syrup for better taste (this halves the per-mL potency — the math below covers both).
7. Cool and store. Let cool to room temperature, bottle into 1 oz dropper bottles, and refrigerate.

Dosage Math

CBD or CBG version: 2g isolate at ≥97% purity ≈ ~1,940mg per batch

• Undiluted: ~180mg per ounce (~6mg per mL)
• Diluted 1:1 with Torani: ~90mg per ounce (~3mg per mL)

THC version: 1.2g of decarbed THCa isolate or ~85% distillate ≈ ~1,020mg per batch

• Undiluted: ~95mg per ounce (~3.2mg per mL)
• Diluted 1:1 with Torani: ~47mg per ounce (~1.6mg per mL)

Serving guidance: the dropper bottles make measuring exact, so use them. For the THC version start with 1–2mL undiluted (≈3–6mg THC) or ~3mL of the diluted version (≈5mg); for CBD/CBG, 5mL ≈ 30mg is a sensible starting serving. Consumed in a drink, this is still an edible: onset runs 45–120 minutes and effects last 4–8 hours, so wait a full 2 hours before a second serving, especially with THC. Check any custom batch size or dilution in our Edible Dosage Calculator, and find your personal range with the dosage calculator.

The THC Version — Pick Your Source

• THCa isolate (~97%+ purity) — needs decarb, highest yield. Hemp-derived THCa isolate is the inactive precursor to THC. Spread 1.2g in a small oven-safe glass dish and bake at 240°F for 30–40 minutes — it melts and bubbles, and it's done when the bubbling stops. Let it cool, then dissolve it into the warm MCT oil in Step 1. THCa converts to active THC at ~87.7% of its weight: 1.2g → ~1,020mg active THC.
• THC distillate (~85–90%) — already activated, no decarb. Dissolves straight into the warm MCT. 1.2g at ~85% → ~1,020mg — identical math.
• Other dabbable extracts (~75–80%) — usually still need decarb. Unless labeled "decarbed" or "activated," give them the 240°F treatment first. 1.2g at ~78% after decarb → ~820mg (~76mg per ounce undiluted), with more cannabis flavor in the finished syrup.

THC syrup safety: a colored, flavored syrup in a dropper bottle looks like nothing in particular — label every bottle with the contents and mg per mL, and store them away from anyone under 21 and from pets. Never drive after consuming, and don't mix THC syrup into alcoholic drinks you're serving to others without telling them exactly what's in it.

Common Failure Modes

• Oil ring or separation on top. The emulsion wasn't sheared enough. Re-blend with the immersion blender for a full minute; make sure the lecithin fully hydrated in Step 3.
• Cloudy syrup. Normal — that's what an emulsion looks like. Clear syrup with a film on top is the problem, not cloudiness.
• Crystallizing in the fridge. Sugar saturation. Warm the bottle in your hand or a warm water bath and shake; adding the corn syrup fully in Step 5 prevents most of it.
• Inconsistent doses. Shake each bottle before measuring — emulsions are stable, not immortal, and a two-second shake re-homogenizes everything.
• Harsh or bitter taste. That's the cannabinoid load in a small volume. The 1:1 Torani dilution exists for exactly this — halve the strength, double the drinkability.

FAQs

What is "Canna Lean"? A cannabis-infused syrup made with CBD, CBG, or THC, designed to mix into drinks or be taken by the spoonful — built as a stable emulsion so every milliliter carries the same dose.

How do you make THC syrup? By dissolving an active THC source into a small oil phase, emulsifying it with lecithin and polysorbate, and blending it into sugar syrup for a stable liquid infusion.

Can I make CBD syrup with this recipe? Yes — swap in CBD or CBG isolate, no decarb needed. The batch math is in the dosage section above.

Why add lecithin? Cannabinoids live in the oil phase, and lecithin (with polysorbate 20) emulsifies that oil into microscopic droplets that stay evenly distributed through the water-based syrup — no separation, no hot spots.

Do I need to decarboxylate? Not for CBD or CBG isolate. THCa isolate and most dabbable extracts must be decarbed first (240°F, 30–40 minutes); distillate is already activated.

How potent is the syrup? THC: ~3.2mg/mL undiluted. CBD/CBG: ~6mg/mL undiluted. Both halve when diluted 1:1 with Torani. Start small (1–2mL for THC) and wait 2 hours.

How should I use it? Add to sodas, teas, lemonades, mocktails, or take directly from the dropper. It dissolves in cold liquids — no hot drink required.

How should I store it? Refrigerated in sealed, labeled bottles. Properly stored, potency lasts several months; shake before each use.

Is homemade cannabis syrup legal? Hemp-derived CBD and CBG syrup made from federally compliant isolate (≤0.3% Delta-9 THC by dry weight) is legal federally under the 2018 Farm Bill and in most states, though restrictions vary. Our isolates — including our THCa isolate — are federally compliant hemp-derived products. Check your state's laws before making or sharing any THC version.
