Can, or will marijuana be detected on a standard pre-surgery bloodwork test?
362847
No, because most standard pre-surgery or pre-op labwork consists of CBC or complete blood count (a count of your red and white blood cells and their conponents) a CMP or a complete metabolic panel (levels of essential minerals such as potassium and sodium) PT & PTT which checks your blood clotting time, and a Liver Panel to check for clotting abnormalities & to make sure your liver can metabolize the anesthesia safely.  Often a UA or urinalysis is done to check kidney function\nIn order to test for marijuana or other illegal pharmaceuticals, a specialized test must be run to specifically check for metabolites of that drug, so although it's not recommended for the pre-op pt, it will not show up in standard pre-op labwrok

Lord I hope so.  I would ask the same question in science and medicine.  It is ridiculous that a driver can be charged with being under the influence of marijuana because a test comes out positive.  Marijuana stays in the system for at least a month, longer depending on the amount of fat in your body.  Because someone got stoned two weeks ago doesn't mean jack when they're driving a car two weeks later.  There's no way to know right now when that person smoked pot, and it's outrageous that they should be charged with driving under the influence when it can't be proved that they smoked a joint before they got in that car to drive.  I'm not sure this was your point, but it's something that really rankles with me.

Toxicology screens (drug testing) done on blood and urine specimens can reveal the presence of many chemicals and drugs in the body. The sensitivity depends upon the sensitivity of the test, the substance itself, when the substance was taken, and the testing laboratory. Blood tests are more likely to detect the presence of an abused substance than urine tests, however, urine drug screens are more frequently done. Opiates and narcotics are usually present in the urine 12 to 36 hours after the last use, depending on the amount used and the frequency. Central Nervous System stimulants such as cocaine can be detected in urine anywhere between 1 to 12 days, again depending in frequency of use. Central Nervous System depressants such as Valium and Xanax are detected up to 7 days after the last day of use, mostly depending on the substance used and how quickly it is eliminated by the body (half-life). Most hallucinogens are also detectable in the urine up to 7 days after the last use. However, cannabis can be detected up to 28 days in regular users. This is only a really rough guide and each person eliminates (gets rid of a substance) at different rates and many factors can influence a test result including how regularly the drug was used. It is impossible to predict whether or not a drug may be present in your bodily fluid or whether the test used will be sensitive enough to detect it.

I wouldn't count on it. It does remove mineral impurities from the hair, but you must use the shampoo AND the treatment.\nI'd be more concerned with the urine test showing a positive result for marijuana. There are not too many jobs which require a hair / follicle sample.\n\nTell her to flush her system by drinking lots and lots of water.\n\n***\nTell her to shampoo 2X with the aloe rid, towel dry,  and then to leave the treatment on her hair for 15 minutes or so and then condition. Do it everyday and it should help.

Urine drug test are almost obsolete these days.  Hair Follicle samples have become mainstream in today's society.  Hair follicles can detect drug usage for several years.  It can tell how often you smoked, when you stopped,  It's really quite fascinating.  Also some companies are using fatty tissue samples, which can detect THC usage for several years.  I'd say you are screwed pal.

Saliva tests can detect THC in your system if you've smoked anywhere from 72-48 hours before the test.  If it's been longer than that you are in the clear.

The Red Cross doesn't test for marijuana use, they test for aids and stuff like that.  T\nThis is something interesting I found that may clear things up about how long it stays in your system for future refeference:\nDepending on your histroy of use, 30-90 days later a test can still come up positive for THC. THC and its metabolites stay in the blood for days and in the fatty deposits of the body much longer. About 30% of THC that is ingested may remain in the body a full week after smoking. Some remnants from a single dose of THC may be detectable up to three weeks later. If you smoke say three to five times a week and have been smoking for 3 to 5 years it can take up to 90 days before marijuana is undetectable in your system.   \nI know many people who have donated and not been marijuana free so don't sweat it.  If they tested for that, they'd have a lot less donations, believe me!!

Depends on your body weight and metabolism.  Weed is fat soluble so it is absorbed into your fatty tissues.  I know some very skinny people who have passed tests after just a few weeks.  My advice would be to excercize as much as possible and drink plenty of water with lemon and cranberry juice (diuretics)  they make you pee.  Do this for at least a month and you should have no problem.  \n\nA hair cut just before the test can help if they do a hair test.  THC can be stored in hair, and employers sometimes test hair.

Alice,\n\nI was at a party nine days ago, when my friends all started smoking pot. I didn't give in to the peer pressure. I didn't smoke any. But I did stay and hang around with them, and I think I got a little "contact buzz" from the second hand smoke. I'm in the military and have a random drug test tomorrow. Will second hand smoke show up in pee tests?? Please help me.\n\nThank You\n\n \nDear Reader,\n\nAttention! It's past tomorrow, so you either passed or failed your drug test. But for future reference, second-hand marijuana smoke — buzz producing, or not — can leave traces of the chemical tetrahydrocannabinol (THC) in your urine for a day or so after breathing the smoke. Usually, the amount is not enough to make you test positive. Most drug tests have intentionally high standards to avoid false positive results due to incidental ingestion of second-hand smoke.\n\nHair testing (which is rarely done because the results are not as reliable as results from urine tests) can give information about someone's drug use over a longer time period, say a month or so, rather than just a few days (for most drugs), or a few weeks (with heavy marijuana smoking, for example).\n\nBy the way, in order for you to test positive for THC, the marijuana smoke would have to be so thick that it would irritate the eyes of smokers and passive smoke breathers alike. Avoiding smoke-filled cars, unventilated rooms, and other enclosed smoky spaces can help ensure that you can hang out while your friends toke and still be clean for bugle call in the morning.\n\nhttp://www.goaskalice.columbia.edu/1289.html

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

Probably Not. The usual panel tests for:\nAmpethamine\nCocaine\nMethamphetamine\nMarijuana\nOpiates

They don't specifically say, but I know the labs test for different drugs all the time.  If there is a new drug, or if a drug increases in popularity, the lab will start screening for it. \nMy recommendation is not to do drugs, and then you won't have to worry about a positive test.\nThey may test for everything, and they may only test for the "biggies" - you never know, and they will never tell.  I have heard of Commanding Officers sending special test requests to the lab.\n\nFrom the link you provided:\nDoD labs are equipped to test for marijuana, cocaine, amphetamines, LSD, opiates (including morphine and heroin), barbiturates and PCP. But not all samples are tested for all of these drugs. \nEvery sample gets tested for marijuana, cocaine and amphetamines, including ecstasy. Tests for other drugs are done at random on different schedules for each lab. Some laboratories do test every sample for every drug.

The presence of blood from your period will not affect the drug test. The test is looking for drugs and blood does not mimic any of the chemicals they are looking for which are actually the end products of metabolizing illegal or abusable perscriptions drugs

Only maybe.\n\n1st NEVER, never take a test without drinking glass upon glass of water the day before and the morning of, you should be p'ing clear.  Then take a b-vitamin that morning, it will add the yellow back to your urine.  Pop a couple rolaids 15 minutes or so before the test, drink a little more water. \n\nWhen filling out paperwork, inform of the vitamins and rolaids, just say you take everyday.\n\nBut if you were "pretty yellow" your urine was full of waste products, the thc will probably show up.  How heavy are you?  The heavier you are, the longer THC stays in the system, as it attaches to fat cells.  So if thinner, you have a better chance of being "clean". \n\nGood luck

Tell your husband that even with infrequent use, marijuana can be detected for up to 10 days after use.  For frequent use, it can be detected much, much longer.

Not likely. Not only that, most places that test for drugs (especially if this has anything to do with "the law") also test urine for dilution, since this is the most common method people tend to use to try to mask (or get rid of) the drug from being detected in their systems. Usually, what else is "looked for" are the common ingredients found in your over-the-counter type supposed "remedies". None of them work anyway, and if your urine is found to have any of those common components (like in those drinks you can buy that supposedly work)- or your urine has too much water in it, or the ph level is off, usually this will count as a "dirty u.a.". Meth usually takes 7-10 days to clear the system, sometimes longer, and there's really not much you can do at all to "speed things up". Your best bet- in the future, is, to not use the drug.\n\n-Tera (time4u420@yahoo)

Yes it does because the marijuana is released into the blood stream when smoked. That's how you get high off this substance and any other substance. If you use daily the pot will stay in your system for up to 12 weeks in some cases.
