you cant really get any opiates with out perscription....try going to your doctor and saying u are having some kind of pain...like make something up, you feel off a ladder or whatever. I cant belive you have a hard time getting hydrocodone tho, I have so many friends that sell it from their perscriptions and stuff cuz its so easy to get.
If you are really desperate....you could try making poppy seed tea. http://www.erowid.org/experiences/exp.php?ID=18570 Every one who I have ever talked to about this says it works...and their are a lot of expierences on erowid saying it works. I've never tried it but I probably would if I had the time. Basically the poppy seeds you can get at the grocery contain small ammounts of morphine and codine....so you get a ton of them, do a water extraction, bam, opium tea. Read the stuff on erowid for good details on how to do it. peace.
