How Long Does THC Stay In Our Body Post Administration?
Question: What is a Vaseline UA (urine analysis)? How is it administered? Is it accurate in finding trace amounts of THC in the blood after over a month of non-ingestion of that substance?
Brief Answer:
There is not exactly a match to this.
Detailed Answer:
This is not done and is not a standardized test. Futhermore there is about zero use for it. The active ingredients in marijuana are very oily. As such, they can stick in the fat for a long time. If someone is a CHRONIC DAILY marijuana smoker, the drug builds up in the fat and can be detected in URINE TESTS for 1-2 months after stopping. If you used one marijuana cigarette, it is detectable for about a week.
The standard screen is to use a dipstick that has proteins that bind to marijuana breakdown products. Oily things will interfere with it. A better test is GAS CHROMATOGRAPHY-MASS SPECTROSCOPY. In this confirmatory test, the marijuana substances are first purified, and then flamed or hit with a lot of electricity to produce breakdown products. Those are run through an electric field and the charged particles that come out of it are detected in terms of their size, how charged they are, and frequently other chemical properties. A purification step with oils might be used. But I've never heard of it being used. It would likely suck up the marijuana chemicals much more than chemicals that are used to hide the marijuana. Maybe someone is trying it as a purification step, but it certainly is NOT standardly used, and it is not in the medical literature, nor is it standardized enough for court.
