We just made some weed milk, we added a little butter to add some fat into the mix, ( we were using 2% milk. ) We used ground stems and used a double boiler for at least an hour. Starting to feel the after effects right now, and we all agreed, it worked. Could be higher, but we did only use stems! We mixed in some Nesquick chocolate mix after it was done and took it as shots. It was yummy

So long story short, yes milk will work.
