I wouldn't worry about either one, HOWEVER since I do not know the [morphine] in your seeds, I don't want to be responsible for killing you. At LEAST titrate your solution; drink a moderate amount, wait an hour and see how you feel, then drink more if you aren't feeling it or want to up it.I actually find it EXTREMELY easy to assess PST strength. Your golden rule is bitter=better. Morphine and codeine (and most alkaloids in fact) are moderately to intolerably bitter. This is no accident - it's evolution's way of telling you to be fucking careful what you shove down your throat lol. That is the number one way of gauging strength. Another is color, but beware - this can be very unreliable! IN GENERAL, the color you want is brown, brown, brown. A strong tea will be a deep, puke-yellow color with hints of brown. A knock-you-off-your-ass-and-die tea will usually be purely brown or dark brown. However, even the darkest of teas will become much lighter if you use too much water. If you drink it all, you're obviously still getting the same, entire dose.
Where do you get your seeds? Generally, the cheaper they are (price wise), the better. That is because they are usually washed less than high-quality ones before packaging. Now, normally, multiple washings are desireable. Not here - you want em as rugged and natural as possible. The unwashed, opiate-rich seeds tend to be black, not grey, and if you're really lucky they will have teeny brown specks throughout. These are bits of the pod itself, and much stronger than residue on the seeds. Still, even the most washed and packaged seeds can often give you a BIT of a buzz if you use enough and your tolerance is low. But if you shake em up like crazy, do it properly and strain them right, and the water is a greyish white or very pale yellow....sadly, you're not gonna be too happy with it.
On the other hand, you can apparently order seeds online from Australia where it is NOT legally mandatory to wash their poppy seeds at all! I've heard stories about shipments of delicious, black and sticky seeds with pod residue everywhere.. My spinal Substantia gelatinosa mu receptors are itching just thinking about it...but for God sakes, if you do go that route, BE THE FUCK CAREFUL OR YOU WILL DIE!!! You seriously can NOT mess around with unwashed seeds unless you know EXACTLY, and I mean fucking EXACTLY what you're doing!!! Even experts should only start off with a SIP! A very good thing can turn into a horrifically BAD thing very quickly. Also make sure you use with a sitter.
