actually, you need wayyyyy more than 50 mere poppy seeds. I'm not going to count how many poppy seeds there actually are but you're going to need about 300 grams worth of poppy seeds. you can usually buy them in bulk at your local "everything" store like kroger, meijer, walmart, etc... What you do is, is you get all 300 grams of seeds, and put them into a bowl. Add lemon juice/ potent lemonade till the water level is about a cm above the seeds so they are completely submerged. So, in simplified terms: About 2-3 handfuls of poppy seeds, add lemonade, stir. and REALLY stir it. LEt sit for 15 minutes, stir again, and then pour out all of the poppy seeds and lemonade into a strainer, like a tshirt or anything cloth. strain all of the juice into a cup/whatever you want to drink it out of. and throw away the seeds. So now you have a very potent drink in front of you. should be a hazy yellowish color. Have fun, only drink as much as you think you should (cause you CAN overdose for having too much.) Please dont hold me responsible for anything you do, im only giving you my opinion off of personal experience.
