I actually wrote a guide on how to accomplish this very thing. However, before you use the search engine for "how to liquid morphine from time release tablets" or something like that, (I'd link you but I'm using an iPod to post this) you MUST know that it is flat out idiotic to take nearly 100mg of morphine IR (provided you are able to break the time release as my guide explains how to, and again, it is NOT for injection, but rather to create your own type of Oramorph/Roxanol for oral use or for more experienced, definitely not opiate naive users, for rectal use which has more than twice the amount of morphine that is absorbed into the bloodstream due to the rectal ROA bypassing the liver and thus, bypassing the significant first pass metabolism. Depending on the patient on a case by case basis, which should go verbatim, a substantial amount of orally dosed morphine is metabolized into it's [less potent] metabolites, leading to the very common misconception that "Oh, I thought morphine was supposed to be hardcore shit! I just took 60mg ER orally and I feel significant pain relief and most people report steady but less intense euphoria, sedation, sensations of floating (especially for those of you who are not chronic pain patients who are seeking to benefit from the higher bioavailability (the percentage of the active ingredient ingested via a route of administration, known as ROA).
For morphine, standard routes of administration include:
-oral dosing of untampered tablets (You should not be tampering with the time-release mechanism if you don't know for damn sure that you know what you're doing. DO NOT UNDERESTIMATE THE POTENCY OF MORPHINE.
-Intravenous dosing of liquid morphine that is pharmaceutically intended, designed, and produced with the intention of the solution, often stocked in vials or ampuoules
-rectal dosing via careful and informed usage of taper-tipped oral syringes and liquified morphine tablets (via proper prep process, a search will pull up the guide I wrote on this)
The nasal route should never be used with morphine. It's ineffective and stupid. Respect the drug or it will put you in your place.
