It depends on the drug in question, the particular metabolism of the user, and whether they're an occasional or chronic user. Some drugs clear below the detection threshold in a few hours, others can be detected for weeks.
There can be other factors as well; for example, some (legal) over-the-counter medications can affect drug retention times (usually making them longer, so don't go getting ideas).

Is a blood test faster then uraine for a pregnant test?
I'm not sure what you're asking, but I think I get the picture. A blood test is not faster than a urine test, but it can show a positive result before a urine test. Most urine tests will be positive on or before the day of your expected period. Blood tests can show positive about 3 days after fertilization occurs. However, a urine test takes 3 minutes to do and a blood test will take hours, even maybe a day or two to get back.

Can you get a negative urine pregnancy test even if a blood test comes back positive?
I have just this minute come back from the doctor. My urine test was negative but my blood test was positive. I have been told that my HCG levels are extremely low therefore producing a negative urine test. I was also told that I am either 1-2 weeks pregnant or that I am in the process of a miscarraige. I had an internal exam and my cervix is closed which is a good sign! I would suggest to you if you had the same thing happen to wait a few days and go back and have both tests done again to see where your levels are at. Either way, keep a close eye on it. Hope this helps.
