7 - 30 days, dependent on metabolism.\n\nTesting for weed\nhttp://www.marijuana.org/BeatDrugTesting.htm

The chemical in marijuana, THC, is absorbed by fatty tissues in various organs. Traces of THC can be detected by standard urine and blood tests for about 2 days up to 11 weeks depending on the persons metabolism, how much they smoked and how long they smoked. THC can be detected for the life of the hair. Again, the sensitivity of the test ranges from person from to person depending on many factors including the amount of body fat, differences in metabolism, and how long and how much they smoked.

It depends on your bodies metabolism but the safe rule of thumb, and I don't care what anyone says, is at least 30 days, no matter what amount was smoked, no matter how much water you drink. Just because THC is not easily broken down and flushed out of our system by water. Now true some bodies may process it faster, and drinking an @$$load of water may or may not speed the process up, but why take that chance? Go at least 30 days.

It depends what is being evaluated. In drug testing, urine can be kept for a long time, years even.  For all testing, if it is stored properly - long periods may elapse as well.  If the pourpose is to evaluate for infection - immediate evaluation (same day or 24 hours) is best.

The amount of time any drug can be detected in one's system can vary from person to person and test to test. It certainly can also depend on the amount of the drug taken and when it was taken relative to the time of the test. Keeping in mind that there is no 100% hard and fast rule for how long a drug will be in one's system, Cocaine can stay in your system for approximately 5 days\n\nYour whole drug history is stored in your hair until it is cut. Some types of shampoo and bleaching of hair may remove drugs from the hair.

CHEMICALS STAY IN YOUR BODY FROM ONE HOUR TO A LIFETIME.\n\nThe length of time any drug (illicit or prescribed) stays in your system will vary.  The time depends on on your physiological makeup (e.g., your physical height, weight, your amount of body fat, your age, current state of health, whether or not you exercise mildly - aggressively - not at all.).  One should consider whether or not one is currently undergoing any degree of stress\n\n\n\n\ntry this site below\nDRUG DETECTION TIMES\n\nThese detection times are for urine, blood or saliva and NOT FOR A HAIR DRUG TEST

i passed a drug test by 1> eating asprin it messes up the test. before you have the test they will ask you if you have taken any medications and tell them asprin. \n2> drink lots of water untill you pee clear they will have you pee in the cup twice because there will be no toxins in it even the natural ones that are supposed to be there because your urine will be very deluted.\n 3> eat lots of food, marijuana stays stored in your fat cells for 28 days and its slowly released in your urine for 28 days depending on your calorie intake so if you eat lots before the test it will stay in your fat cells more because yoour fat cells have more room to suck it up

it depends on the type of test; if it is blood or urine, depending on your metabolism, between 2-5 days, faster if your metabolism is high (ie if you are thin it is probably faster, and if you are bigger vice versa) It also depends on your usage, if you are habitual, it could take somewhat longer than if you are an occasional or one time user....if is is a hair follicle test, it depends on your ethnicity, but it could go back up to 18 months depending on your hair color and length (shorter for blondes than brunettes) this info should be pretty on the mark... thc from marijuana stays in longer because unlike coke, it is stored in your fat cells

THC is stored in your fat cells and the only thing to get rid of it is time.  The length of time can vary depending on your usage but usually 4-6 weeks of non usage will get you clean.

It depends on alot of factors...\n\nhttp://www.concept420.com/how-long-does-marijuana-stay-system.htm

i was in the same situation as you. i smoked 2 days prior to the mouth swab and still passed.  jus make sure that you get as little saliva on the swab as possible... maybe eat/drink somthing before hand.  I'm not a chronic smoker (sorry for the pun), but i do it once in a while... \n\n"In a study using RIA (Radioimmunoassay) test, cannabinoids were detected in saliva 4 to 10 hours after subjects smoked a single marijuana joint."\n\nYou Should be fine... Good Luck.\n\n-CAP

THC in weed lasts for 30 days. BUT you can still test positive for it up to 3 months later.

I think it is commonly reported to remain detectable for 30 days;  from:  http://www.craigmedical.com/drug_test_faq.htm\nTHC (marijuana): Tetrahydrocannibinol (THC) is an active component in marijuana. Marijuana, a hallucinogen, is commonly ingested by smoking, but it may also be eaten. Marijuana may impair learning and coordination abilities. Marijuana is most commonly the drug of choice among teenagers and young adults. The hallucinogenic effect of Marijuana can lead to irrational behavior, disorientation, and paranoia. Low concentrations of THC persists in urine at a detectable concentration for many days after smoking. Marijuana is the most common recreational drug of abuse.\n\nflush?:  http://www.passyourdrugtest.com/

One-time use usually shows up for 24-72 hours.  Habitual use can stay in your blood up to 2 months, according to the charts at my work.  I guess smoking it "occasionally" would fall somewhere in between.  Tobacco and alcohol will not show up because they don't test for them.

it depends.THC stays in your fat cells.the more fat you have,the longer it will be there.urine test-don't smoke for at least 1-1 1/2 months.blood-2-3 months.hair-7-8 years possibly,depending on length.hair grows on a human head approximately 6-7 inches a year,arm,chest and underarm much slower,legs faster if you shave them,beards can grow really fast,sometimes up to a foot a year.niacin and cranberry juice can help to clean it out quicker,but to much niacin can poison your system.salads with red-wine vinegar and oil help also.

How long drugs are detectable in the system depends on a number of factors:The drug taken, How much and how often taken,Body weight, Individual metabolism A single hit of cannabis may disappear in a few days, whereas heavy or chronic use can be detected in urine up to a month after stopping.\n\nMarijuana can be detected in your body for up to 30 days. There is no way of cleaning marijuana out of your system faster, you can only give it time.
