Yes, chuck them....jk. Well obviously you could use the seeds to plant, and keep the females you get, clone them, etc etc yadda yadda. As for the stems, they MIGHT have some THC on em.....my solution is to just throw it in some oil and put it on low heat for an hour or 2 (really low heat) and stir often. Then strain it out, and use the oil in recipes...see how strong it is, if anything. That's all I got, hope it helps!
