I've had many good results with this. With the right amount of butter, oil, and maybe milk...you should get a pretty potent drink. Personally, whenever I did this, I usually used stems, shake, resin, ash, leftover kinda deal, stapled closed in a regular tea bag with some bud to make sure it works.
My understanding is that stems vs. bud vs. resin all has different chemical contents (body buzz vs. head high etc etc). Can't think of the names or a source at the moment, but i'm sure someone else knows what I'm talking about. Anyway, my advice would be to use tea as a supplement to smoking, to get the most out of your stash. And if youre looking for a stronger experience, stick to edibles.
Might be a strange analogy, but I always looked at tea in the same league of respecting a plant the way that native americans respected the animals they hunted

. Then again, it's not always the most appetizing thing to consume massive liquid butter. Eh.
