In optimal conditions plugging it should work. Never tried it but so long as the morphine content is high and the solution isn't too oily, it should work.
Not sure how much you actually dosed, but I just grew a small batch of pods for the very first time and the resulting pods are the strongest I've had in my life. I used to be a daily poppy pod tea user (via podspresso) for around 18 months but I never came across pods that required such little material. The other day i ran just 6 grams of dried pods through my espresso maker and the resulting liquid was ominously vile, it tasted different than any pod tea I've ever had. Aside from being intensely bitter (which is normal) it had an unusual and overwhelming spiciness to it that made it very difficult to drink. It tasted poisonous. I was pretty worried that I was going to give myself noscapine or thebaine poisoning. But no toxicity occured. What did occur was an intense, long-lasting high that keep going for a solid 20 hours, completely pinned pupils. Pretty stimulating, but pod tea is always stimulating to me. Felt great though, especially given that I was worried that I was about about to poison myself when I initially drank it.
Blows my mind that only 6 grams of dried pods did that. And I only drank the first run through on the espresso maker (i drank the second run of those grounds at a later date and still got high). I've been pumping them full of nitrogen fertilizer (dried blood) on a daily basis which seems to have increased alkaloid production. Also, I think that poppies are much stronger if you cut them before they fully mature (ie, before they start producing black seeds). All the dried pods I've ever purchased were fully mature and contained black poppy seeds. But I've found that if you cut the pods off right before they start producing seeds, the resulting pods are much stronger. When they go into the seed producing stage they seem to shift focus from alkaloid production to seed production, thus reduces morphine content. These feel like they are a bit over 2% morphine content by weight (dried seed capsule), which is clearly a product of the controlled nature of growing them indoors and with large amounts of nitrogen fertilizer. I suppose like indoor marijuana versus outdoor marijuana, poppies grown indoors are stronger than ones grown outdoors.
Unfortunately I'm not trying to use opioids these days, so I'm trying to use what I have left as sporadically and infrequently as possible. Which is difficult since these pods are very good, the strongest I've ever had by weight, but I have an extensive history of opioid addiction. Don't think I'll grow poppies again anytime soon, was alot of fun to witness but I just don't want or need to have that stuff around. My girlfriend seemed a bit concerned given how fucked up I got, I looked very tired and fucked up with distant pinpointed glassy eyes yet I was also simultaneously very stimulated, decided to start shampooing the carpet in my office at 5am in a sort of opioid daze.
