Morphines oral bioavailability is around 35% so if you plan on popping them then no they will get you no where near as messed up as an Oxy 80. Oxycodones oral bioavailability is 100%. Though if you have no tolerance you could probably just eat a few and get buzzed. Morphine lasts longer than oxycodone or hydrocodone and the high is more sedating. It is more of an analgesic than a euphoriant/analgesic at low doses. Take two or three and see how you feel in 45 minutes. It will do what every mu-opioid agnostic does euphoria, analgesic effects, anxiolytic effects, possible itchiness, flushing of the face, constricted pupils, possible nausea/vomiting, lethargy.
