Depends on you . . .: Half life of morphine or any other drug represents time for drug concentration to drop by 50%. This can be affected by metabolism & health of kidneys & liver, as well as formulation (immediate vs extended release) & route of administration eg oral vs injection. Iv morphine has half life of 2-4hrs (http://www.Drugs.Com/pro/morphine-sulfate.Html).

Drug Testing : I am sorry, but there is no physician here who would want to help you beat drug screening tests. We all are united in that we believe you would be healthier clean and sober and to be in recovery. Hair screening is permanent until you cut your hair. Urine tests can be positive for about a week now. Please get into recovery. The joy and fellowship can be miraculous.

4 hour half life: The time to process half of a dose of morphine from the system is listed at approximately 4 hours. So, half of the amount is out at 4 hours, half of the remaining amount is out 4 hours later, , half of the remaining amount at 4 hrs later, etc.

1.5-7 hours times 5: Therefore, the answer is 7.5 to 35 hours.

Variable.: The elimination half life (or time required for the morphine to fall to half its previous value) is about two to four hours. Certain tests however can be very sensitive and detect small amounts of morhpine in the system for quite some time after this.
