Far more likely that (much like thanksgiving meals here in America) that eating a lot of food and partying makes you tired. Opium comes from the dried sap of an unripe poppy seed pod. Not dried and baked seeds.

You do know that opium comes from the sap of the unripe poppy seed pod right…and not the actual dried and baked seeds? I think you should do a bit of research before making half baked (or fully baked in this case) connections. If it was that easy to create that strong a reaction from just the seeds they would be far, far more controlled than they are.
