Blood Drug Testing

What comes up in a blood drug test?

I think I am getting a blood drug test done for a job next week I have had a clean system until last night I smoked weed. Are blood test more sensitive than urine is there anyway to clean out my system? Ok well what about me smoking weed once? Im not a drug user at all I had a lapse in judgment one night. I have been given one weeks notice.

3. Blood tests are much more sensitive than urine. Depending on what they are specifically testing for, they can find WAY more information through blood than urine.
4. If they take blood you will fail it now if they used urine you might be able to slip some different urine in on the drug screen
5. While THC can remain in your system for up to one month, a small amount probably will not. This will depend on your body's fat content. Ideally, you should try to exercise constantly to burn up as much of this as you can. You'll want to stop exercising about 2 days before the test and eat lots of fatty food. This new fatty food will hopefully be the fat your body will burn rather than the fat that has THC stored in it. Keep drinking lots of fluids, especially cranberry juice. Yes, blood drug tests are highly sensitive, and there is no way to guarantee you won't get caught. I would actually be surprised if you are getting a blood test, as they are much more expensive. Even urine tests can be highly effective depending on the method they use to check. Simple positive/negative kits aren't worth much, but when urine is analyzed on multi-million dollar instruments (which most of them are), drugs can be detected in ridiculously small amounts. On a side note, drug tests don't test for all "drugs". The company that wants the results has to specify what drugs they are looking for. Tests typically include the 5 or 7 most commonly abused drugs, which almost always includes THC, and can also include, cocaine, amphetamines, barbiturates, benzodiazepines, and more. If a test is determined positive for amphetamines, they can then determine via thin layer chromatography exactly what amphetamines are in the system (amphetamine, methamphetamine, MDA, MDMA, etc). It's somewhat humorous that the least harmful drug (Marijuana) can sometimes be detected for up to a month, where harder drugs like ecstasy and cocaine can only be detected for a couple of days. Some drugs, like psilocybin from "magic mushrooms" can't be detected at all.
