Nope never tried it. It should work fine. Lots of people decarb their weed which you won't be able to do. Other then that I don't see a whole lot of problems with doing it. Live shatter comes from fresh resin.
One thought. More Chlorophyll might leach out of the leaves with fresh weed. It shouldn't effect the strength but might effect flavor.
One thing to mention. I have switched to making Coconut oil for baking. It is a lot easier then Butter. You don't need to clarify it first.
