To make cannabis milk you will need some dried weed, keef and a glass of milk. Chop the weed down or grind it. Put the keef and dried weed in a sealed pot and place them in an oven preheated to 200 degrees in order to get the THC to full potential. Then you will have to add the dried product to a pot and add milk in it. Put it over another pot filled with water. The trick is to keep the water boiling without boiling the milk. Make sure to stir gently for 30 minutes. After that strain the product into a plastic container, let it cool and put it in the fridge.
