If you are asking how long it takes for a particular drug to get out of your system for any reason other than passing a drug test, call your doctor or pharmacist for that information.  If you are concerned about passing a drug test, following is the information you need. 

If you are taking a drug that has been prescribed for you, all you have to do is take your prescription with you to the drug test and there should be no problem.  For more information about employment-related drug screenings, read: "Passing" Those Drug Screenings

If you are taking drugs other than those prescribed for you, we need to tell you that doing so is both dangerous and illegal.  If you're taking them regularly and need help stopping, please see the National Alcohol and Substance Abuse Information Center's Web site.
