Morphine has a poor oral bioavailability (30% ) and an even poorer nasal one (15-20% ) according to our
bioavailoability thread - it also says that rectal has the same bioavailability as oral, but I have heard a lot of anecdotal evidence on here that plugging does work better so it's probably worth a try...
I have a theory about why people claim plugging produces more pronounced effects even though bioavailability is the same as oral. So why, if the Bioavailability is the same do people claim to feel more of an effect from plugging vs. oral? I cannot say for sure, but I think it has something to do with the fact that the solution takes longer to be absorbed by your stomach vs. your ass. The more rapid absorption of rectal administration leads to a quicker onset and more pronounced initial effects vs a gradual comeup produced by oral administration that may be less noticeable. Somebody has probably already speculated and posted about this already so sorry to waste your time if this is old news for you.
I have posted my method of prepping MScontin for oral/rectal administration because I have done it alot. It is something that took awhile to get right and I have lost some MS in the process.
If I was to ingest morphine I would take it one of three ways: sublingual, oral, or rectal.
A) Sublingual MScontin... Hold the extended release pill under your tongue for as long as it takes to dissolve. It can take quite some time for the tablet to fully dissolve, but I have found that this is an effective ROA. Takes about 15 minutes for a buzz to kick in, but once it does it builds on itself and effects basically increase until the tablet is fully dissolved. Plateau for about an hour with gradual comedown.
B) Oral/Rectal MScontin preparation is the same (I have syringes that I use specifically for oral and syringes that I use specifically for rectal because who really wants to put something in their mouth that was in their ass the day before)...
Put a cup of water in the microwave and boil (make sure the cup is microwave safe I use a pyrex measuring cup).
While the water is boiling pulverize your MScontin and dump it into an oral syringe being careful to hold your finger on the tip so the powder does not leak out. Once you dump the powder in the oral syringe take the plunger and kind of wiggle it into place making sure it is far enough in so that it will not fall out when you turn the tip upwards but not so far in that you build air pressure and blow your MS out of the tip when you remove your finger.
With the plunger in place and still holding the syringe with the tip down turn the syringe so the tip is upwards and flick it with your free hand so that the MS falls down onto the plunger slowly remove your finger (I always hear some air release itself from the tip this is why you want to flick the syringe so you do not blow MS out of the tip).
Push the plunger up until the MS powder reaches the top
DO NOT COMPRESS THE POWDER OR IT WILL NOT DISSOLVE COMPLETELY!!!.
Take your hot (just boiled hot) water out of the microwave and go to your sink.
Hold the tip of the oral syringe upright against the side of your cup then slowly pour water over it and draw water into the syringe (I usually get about 5 ml water into the 10 ml syringe), and quickly put your finger over the tip and shake the hell out of it. If you don't do this fast enough the MScontin will gel up and you won't be able to get it to dissolve.
Hold the oral syringe upright with your finger still on the tip and draw back on the plunger while removing your finger (if you don't do this whatever solution is stuck in the tip of the syringe will squirt out and you will lose a few mg of what you put in). This has something to do with the hot water causing expansion of something, (air?) what exactly I don't know.
Now you can push the plunger so the solution fills the tip and turn it upside down into your cup of water and fill the rest of the syringe by drawing back on the plunger. If you do not get all the air out of the syringe before you do this you are likely to lose a little bit of the solution when you turn the tip upwards or downwards.
If I take the solution orally I squirt the solution into my mouth hold it as long as I am comfortable to absorb some sublingually and then swallow.
If I take the solution rectally I follow the plugging faq i.e. have a bowel movement, get something to read/occupy 15 minutes, get comfortable on my left side, lube, plug, relax and allow the solution to absorb for 15 minutes while I read or use the computer (I reccomend you take some baby wipes with you to clean your hands and ass after you plug so you don't get whatever you are going to use to occupy your time dirty).
PLEASE NOTE: I will be back to add to/ revise this post I have other things to do now.
