The only thing you need to be careful with with RSO is dosage (it’s a concentrate, and it DOES have hands), and making sure it doesn’t overheat, since it’s already been decarbed. Basically the only way to fuck it, though, is to use it as a frying oil. Baked goods? Mix that shit in the oil component (I’ve heard coconut oil works best) and follow the instructions
So, I’ve baked RSO brownies. Pushed a full 1000mg syringe (685mg THC) into the oil. At least for the specific brand I buy (bc it’s what my local dispo carries) the smell is almost nonexistent when it’s actually baking, but you can smell a little when you’re dissolving it into the oil.
