Much has been written to support the fact that seeds contain little, if ANY, psychoactive properties. Most likely you are getting a bit of tar from "contamination". Check out some real info on some opium forums; don't post opinion that gives people bad info.
It takes a lot of poppies to get a gr of O, but it's not too hard. The flower opens at about 90 days, and the petals fall off after a couple of days. Now you'll see the pod, which will grow and swell for 10-14 days. The color changes from green to a hazy blue and the the little spikes on the crown will point up. To harvest you scratch the pod - sometimes I use a needle, sometimes an x-acto, but the cut is very shallow. You should see latex oozing immedietely; this is pure raw opium and can be used as is. The Chinese cook it down, the Hmong people smoke it straight.
My advice is to collect latex and save it until you have a decent amount, otherwise you don't quite get there and you,ve used up your O. I sometimes wipe the pods with some gauze and just let it dry. Use the same cloth for awhile and keep letting it dry. when you finish harvesting the pads are soaked in water to release the O. Evaporate the H2O and you have pure O. (Water should go thru a coffee filter before evap.)
Most people let the pods dry on the stalk and grind them, minus the seeds, to make tea. 2 or 3 pods is a lot like a few percs.
Poppies are opposite MJ in many ways:
* O is water soluble, MJ resin is not
* Poppies flower in a long day, short night
* Poppies like the PK early, and the N at flower.
My seeds were scattered in March and are coming up nicely- if you want to plant, do it now. Remember, they need the long days in July to flower.
