For this delicious canna coffee shake, ideally you want to leave the cannabis in the milk overnight. This will draw out the THC. Grind the cannabis into a fine dust before adding to the milk.
The following day put the milk, ice cream, vanilla and coffee into a blender. As you probably guessed you then simply blend the mix until creamy and smooth.
Now simply sit back and enjoy. You can also replace the coffee in this recipe with hot chocolate powder and have a chocolaty shake instead.
