actually ive done heroin oxy darvocet fentanyl morphine... every opiate and opiod out there... and heroin isnt that much better then strong oxy, fentanyl, or morphine.... the only opiate that hasnt got me completely fucked up was darvocet. they all have the same feeling, but some differnt variations. heroin and oxycontin are the most similar ive done. so try the other opiates out there before you call them boring. idiot.
