So I'm hoping someone can help me understand the blocking affects that some opiods have. Could either methadone or bupe be iv in such small amounts that they don't have any effect besides a blocking effect against other opiates like morphine, dilaudid, or heroin? I'm going to assume not, but I wouldn't know better as I don't understand how synthetic opioids work. I just hope somebody else does and can answer my question thank you
