Well, they have got extremely small amounts of THC, some people make tea, but its really not worth it.

I chew em too, i love the taste of them, but tbh i dont many stems, i used to, but now it really is just bud and all bud

I got 2 Oz's today and i only got like 2 stems in the whole thing, the rest of the buds in nugs with no stems. It's all stuck together with the trichs
