Any drug you take has to run it's course through your system. This process takes time. With morphine it takes 3-5 days. There is nothing that can speed it up..just have to wait. You can try exercise or energy drinks to speed metabolism but it will still probably take the same amount of time.
Morphine is an opiates and can be used in many medicines like pain killers. In urine, detection time of Morphine is 2-4 days, in blood for 6 hours and and hair follicle test for 90 days. All medicines should be used for therapeutic use only under the prescription of doctor. Otherwise, this these drugs have many side effects and also can cause problems in getting jobs.
