Best Answer

That really depends on which drug, how often it's been used and how long it's been since you've last used it. For instance if you smoke pot every day for a month (or more) you've got to go cold turkey for about two weeks before you can pass a blood test. It will still show evidence of the pot in your blood but not enough to mean you've ever used any.

How many days drugs stay in your body?

The exact timetable for how long drugs remain detectable in urine, blood and saliva tests is almost impossible to determine. The reasons for this is that every body intake and out take is different.


How many weeks does it take to know that your pregnant?

This will generally depend on the test that is used to detect a pregnancy. Blood tests are more accurate in that they can detect a pregnancy earlier. As soon as two weeks after a missed period, blood tests can detect levels of Hcg (the hormone pregnant females produce). Urine pregnancy tests generally do not detect a pregnancy before the 6th week because sometimes it takes that long for Hcg levels to rise to the point where a urine test will be sensitive enough to detect it.

How long does an allergen such as cow's milk remain in breastmilk?

Some cases have been known to take a week, where others have been known to take a day. Basically it is along the same lines as Drugs and alcohol, when the contaminant is no longer in the blood stream, it should also no longer be in the milk. There are other factors involved though, such as how long it takes contaminants of the blood from being filtered out, so it is generally best to consult a doctor when removing possible allergens from your diet as they can monitor your bloodwork as well as do tests also on your milk quality if needs be.
