I like to IV 50+mg morphine, but i have a retarded tolerance to opiates. maybe all the smack has something to do with it.
anyway, ORAL MORPHINE SHOULD BE AN OXYMORON! your liver destroys almost 90% of it before it even hits your system, so youre going to be wasting most of it by eating it. also, i find i get sick from oral morphine. on the other hand, sustained release morphine is kinda hard to defeat, so rather than simply crushing it, i recommend a coffee grinder. you can then snort away.
i would start with 10-15mg.. when i had no tolerance, this much up my nose would get me into dream world. it was great.
