No you dont need to cure it, you are only after the dry, ripe trichomes, which is what you have after drying. Curing isnt going to increase the thc so i dont see why it matters
No you don't need to. Fact is, you dont "need" to cure bud you're smoking either, it will just improve the taste.
Personally i make most of my edibles from trim that has had not cure at all, it goes from the plant to the freezer to the butter\oil. I've never had anyone complain about the flavour or quality.
