I collect my leaves, stems, etc., grind them up and make canna-butter. Using a double boiler, dump all of the ground dried leaves, stems and a couple of sticks of butter into a double boiler. Bring the temp up to the water beneath until it is simmering. Let it simmer for about 2 hours, stir every 20 minutes. Pour the mixture through strainer with a coffee filter. I recommend pouring the butter into an ice cube tray and freezing it. You can also make regular canna=butter this way. It works amazingly well.
