    Hi,

    SWIM usually does about 1/4 to 1/2 of a MS Contin 100mg, and he does it IV (with a pill filter of course) and is curious about the effects of IV use vs IM as he recently heard the in a medical setting Morphine is usually administered IM.

    SWIM notices that the effects IV feel like his body is seizing up and sometimes experiences pins and needles sensations, along with a pleasurable rush. SWIM's question is would the effect and rush of Morphine be different if administered IM?

    Also, would he have to use more of the pill IM to experience euphoria on a satisfactory level?

    Thanks!

    Intramuscular injection will not have any rush. The rush is caused by the drug entering directly into your blood. The bioavailability of iv morphine is 100%. I'm not positive of the ba of intramuscualr morphine but I believe it is around 40ish%. So yes, one would need more im morphine than iv morphine but you will not get a rush like iv. It will feel the same as orally taking it except it will kick in a bit quicker and will be a bit stronger since the ba of oral morphine is around 30%.

    Glad to hear you are reducing risk by using a wheel filter.

    Great Info Swi-Sir!

    SWIM has noticed that the euphoria experienced from oral morphine is greater than the euphoria from IV morphine - not including the rush from IV.

    swim had a surgery a few years back and was hooked to a drip, and a morphine pump, swim was in alot of pain, dr. uped his dose and lowered his pump so swim could hit the button every five min. swim did not get a rush but swim did go to sleep after four or five hits of said button, swim nearly took a dirt nap that day, all turned out ok, but swim has never got high or got a rush from morphine, regardless of the route of administration, swim never plays with needles and veins, only dr's., and nurses have access to swims veins. be safe all.

    ^^That's because the morphine solution is highly diluted and injected very slowly into your bloodstream with those pumps. After my mom's shoulder surgery, they gave her a shot of morphine and the syringe they used was huge. Probably like 20ml, maybe more and it only had 5mg morphine in it. The nurse also injected it very slowly. It took her probably 3 minutes to shoot the whole syringe. The rush you get from IVing opiates is that they are being super concentrated in the syringe and injected very quickly into the vein.

    I quote from Saunders Nursing Drug Handbook:
