Blood Drug Testing

How much time is required to pass before you can pass a drug eg) drink driving test. I have heard 6 hrs?

Hi in Australia we now have drug testing just like drink driving testing. I always thought that drugs stayed in your system for 3 days approx. but it must be less time to actually pass these tests. Please help I don't want to get caught.

1. It takes no time at all if you don't use them in the first place.
2. Depends on the drug. I am a military defense attorney in the US. We test drug use and I defend the soldier. For urine tests: Cocaine and meth are typically out of the system in a few days (generally 3), while Marijuana may be in your system 30 days or more. With hair-follicle testing, they can go back months even with cocaine. It's not as reliable as a test, but can be used nonetheless. Regardless of knowing this, soldiers get caught ALL the time for drug use...so don't try to beat the test or press your luck...not worth it. It takes a while for the drugs to be detected in your system upon ingestion, but I don't know that amount of time. What the tests detect is not the drug, but certain metabolites produced by the body when metabolizing or breaking down the drug. I imagine they can detect it in about 6 hours. No one wants to get caught, but people get caught all the time...best bet...stay off the stuff if you really dont want to get caught.
3. i know that pot/hemp/ weed whatever you call it might take 30 days, as for the rest i stopped years ago ....good luck
