Prepare your cannabis oil by ensuring it’s at room temperature. If using cannabutter, melt it gently and let it cool slightly. The key is having your cannabis fat ready to incorporate smoothly.

Combine the cannabis oil with 2 tablespoons of warm milk in a small bowl. Whisk vigorously for 30 seconds to create an emulsion. This step prevents the oil from separating in your final drink.

Pro tip: A few drops of liquid lecithin will help the oil bind better with the milk, creating a smoother texture.

Mix the sweetener and vanilla extract with the remaining cold milk until dissolved. Add the cannabis-milk mixture and stir well. Ardent FX Decarboxylator ensures your cannabis is properly activated before making oil.

Assemble by filling two tall glasses with ice cubes. Pour the cold brew coffee into each glass, filling them about 2/3 full.

Add the cannabis milk mixture, dividing it evenly between the glasses. Stir gently to combine, creating beautiful coffee swirls.

Pro tip: Pour slowly over the back of a spoon to create distinct layers if you want an Instagram-worthy presentation.

Finish with a dollop of whipped cream if desired, and dust lightly with cinnamon or cocoa powder. Serve immediately with ONGROK UV Glass Storage Jars (2-pack, Child-Resistant) nearby to store any leftover cannabis oil safely.

Pro tip: Make a double batch of the cannabis milk mixture and store it in the fridge for up to 3 days for quick iced coffee prep.

Perfect Cold Brew

Make your own cold brew by steeping coarsely ground coffee in cold water for 12-24 hours, then strain. It’s smoother and less acidic than hot-brewed coffee cooled down.

Half-Strength Option

New to cannabis edibles? Use only 2.5ml cannabis oil for a gentler 7.5mg per serving. You can always make it stronger next time.

Oil Separation Fix

If your cannabis oil separates, add a tiny pinch of lecithin powder or blend the mixture with an immersion blender for 10 seconds.

Dairy Alternatives

Oat milk and coconut milk work beautifully with cannabis oil. Full-fat versions emulsify better than light alternatives.

Temperature Matters

Never add cannabis oil to hot coffee — high heat can degrade THC. Always work with room temperature or cold ingredients.

Label Everything

Always label containers with contents, dosage per serving, and date made. Keep away from children and unsuspecting housemates.

Method Duration Notes
Fresh consumption Immediate Best enjoyed right after mixing
Refrigerated (unmixed) 3 days Store cannabis milk mixture separately
Cannabis oil 6 months Store in cool, dark place in airtight container

Can I use half cannabis oil and half regular oil?

Absolutely! This is a great way to reduce dosage while maintaining the texture. Mix 2.5ml cannabis oil with 2.5ml regular coconut oil for a milder 7.5mg per serving. The drink will taste and mix exactly the same.

How long does cannabis iced coffee take to kick in?

Effects typically start within 30-120 minutes, as the cannabis oil needs to be processed through your digestive system. Drinking on an empty stomach may speed onset, while having it after a meal may delay effects. Never drink more within the first 2 hours.

Do I need to decarboxylate cannabis before making oil?

Yes, decarboxylation is essential to activate the THC. Raw cannabis contains THCA, which isn’t psychoactive. Proper decarbing at 115°C for 30-40 minutes converts THCA to active THC before infusing into oil.

Can I substitute the cannabis oil for cannabutter?

Yes, but melt the cannabutter first and let it cool to room temperature before mixing. Use about 1 teaspoon of melted cannabutter per 5ml of oil. The drink may have a slightly richer, more buttery flavour.

How should I store leftover cannabis milk mixture?

Store the cannabis-infused milk mixture in an airtight container in the fridge for up to 3 days. Always label with contents, dosage per serving, and date made. Shake well before each use as separation is normal.

What if I drink too much cannabis coffee?

If you feel uncomfortably high, stay calm and hydrated. Find a quiet, safe space to rest. The effects will pass, typically within 4-8 hours. Contact the Poisons Information Centre on 13 11 26 if you’re genuinely concerned, or emergency services if you feel seriously unwell.
