Im not sure I always made poppy tea out of poppies, I didt know you could make it straight from opium but im sure I just havent read about it.
you'd be far better off smoking it if it's really opium and not red rock....i'm not sure how one would go about deciding how much opium to use seeing as all opium is of varying strengths, but it's water soluble so whenever you decide on the dosage you'd just mix it into very warm water, perhaps with some citrus juice and a shitload of sugar and something to chase it with. opium tea (at least made from pods rather than opium) is one of the worst tasting things i've ever ingested, and i can't even force myself to stomach it anymore. i just can't do it, which sucks because it can be verrrry nice. but you'd use less and get effects much more quickly and effectively if you just smoke your opium. making tea is for when you can get dried pods (always) but can't get your hands on living flowers or already scraped opium (most of the time for most people)....
OH god the taste of poppy tea, WOW. I gagged alot the first time I drank it. After the 50th time you get to the point where it becomes normal to drink and is fine to drink, heh but its still nasty just not a nasty tasteing.
the other way round for me....the more i drank it, the more disgusting it got....the first few times were rough, but manageable.....i can't even finish one glass of the shit now without puking. the best bet is to plug your nose, gulp down as much as you can and IMMEDIATELY follow it with a few gulps of coca cola (only thing i found decent for chasing this stuff) and then waiting a good ten minutes or so before going for more opium....
