^ha, no. I am not sure what brown powdery material you are talking about unless you mean you crushed the pods after removing the seeds... in that case, its poppy straw.
To get opium, you have to score a living poppy and a white latex substance comes out and you collect and refine that... THAT is opium.
Poppy straw contains the same alkaloids as opium but also a lot of plant material, waxes, tannins and other plant junk.
You could've searched around BL as well as google and sites like wikipedia, erowid, etc. to have your terminology clarified, no need to bring back an old, dead thread that is only tangentially related.
