Idk about that. Back in the day,guys used to make pot tea out of the stems. I keep thinking a pressure cooker worked better though. I guess it's like we used to say-if you remember it clearly,you weren't there.
I have heard of tea, but way back in the day we would add the stems with coffee grounds and make a nice tasty pot of coffee. But I love my beer and don't want weed in it. Besides wouldn't the boil kill the THC?
