when I had my kidney stone I was in misery and snorting 500mg oxycodone two at a time. it didn't make me euphoric, it didn't even dull the pain all that much. the only relief I got was from valium, one tiny pill and I was good to go. opium simply does not work on everyone the same as it does on you. we all have different chemistries, and it just so happens weed (and acid, and cocaine, and benzos) is what does it for me.
