The only poppy containing Opium is Papaver Somniferum. There is also a Paeony Poppy that is called paeoniflorum but is a somniferum. There are MANY varieties of Opium poppies- Persian White, Hens and Chicks, Danish Flag, Tasmanian, etc.. Many of these can be found at regular garden stores, easily available on e-bay, or simply go to the grocery store and purchase a bottle from the spice rack. Most of these are the Tasmanian variety and are viable seeds. The white seeds at a local Indian market will grow white poppies.
If you find dried pods at a florist they are opium poppies. Remove the seeds to plant, and grind the pods to make a bitter tea that feels like 2-3 percs.
Seeds contain NO opiates and do contain oils that make you feel ill.
Let's not hear from some under-18 that some "buddy" of his brewed 1000g of seeds and got really really really high. These forums are for solid information, not ignorant hearsay.
