There are a bunch of other brands on Amazon, and while at Ralphs I saw two different brands. Just bought two 55 grams bottles for $5 total.
As for impressions keep in mind I took three 10 mg norcos about 3 hours ago soon after my workout(take them for recreational use and occasional backpain), and they've certainty enhanced my high is a very subtle way. I feel far more relaxed and my eyelids feel much heavier, whereas norcos give me a more upper high to where I'm not knocked out. I'm not sure if I would've gotten the same feel if I did it by itself.
I just made the tea in the easiest way possible because I really bought them on a whim and wasn't planning to spend to much time. I just put a little cold water and tiny bit of lemon juice match the amount of poppies in the 2 liter coke. Shook it for 15 minutes, strained it, then drank it. 5 minutes later did the same thing as there is still codeine left in the poppy.
I've seen a couple different methods online, and I've also read that some poppy seeds to buy vary in quality. I'm going to keep to see what method works best.
