Round, white morphine sulfate 30mg pills manufactured by Roxane Laboratories, Inc.
Would railing these do me any good? Or are they like MS Contin and I have to plug them? Would 30mg be enough for someone with minimal opiate tolerance?
I'm not sure of what you mean by "minimal" opiate tolerance - a little above zero, due to moderate use a little while ago; or that you generally react very strongly to even relatively small doses, despite the lack of acute tolerance.
Anyway, morphine has very poor intranasal and oral bioavailability, in the 30% region. Unless you are injecting, I suggest you plug. It's hard to get a good picture of your opiate tolerance with the information provided.
I consider myself to be slightly naturally tolerant; to get a nice (although underwhelming buzz), I'll take 300-390mg of codeine, or 300-400mg of tramadol (or more, but NEVER DO THAT - SEIZURE RISK! As I'm sure you're aware).
Having not had opiates for many months, and never used them more than very very rarely, I tried I.V. morphine for the first time. 10mg may has well have been placebo; I plugged another 10mg within 15 minutes and then felt a mild buzz, like maybe 90-120mg of codeine.
A few weeks later - surely after tolerance had subsided - I was injected with 40mg. THIS was something like I was expecting - not a tiny bit too much, but then again I'm larger than average. [DISCLAIMER: You should not I.V. 40mg of morphine if you have no tolerance].
Either way, I.V. is the most efficient ROA but you do need to know exactly what's in those pills, how to filter them out, and how to bang. Plugging them is your next best bet.
I might use 30mg orally for some kind of injury - but not even serious pain. With negligible bioavailability, oral morphine is a poor and wasteful formulation.
