Does a faint line mean you failed a drug test???

Talk to your attorney about this. In some jurisdictions the PO will allow the first test to be a "freebie" and they move on. Other places will test the sample and determine the levels of drugs. Local counsel can help in this matter.

You cannot compare a home drug test to what the courts use. Had a client recently pass a home test and failed a court test the next day. Don't know what the faint line means...my guess is that's a positive for drugs.

Normally the first test is a baseline to find out what is in your system. That way they will know if the next test is less than the first.

no. the presence of a test line, regardless of how faint, indicates a negative result. even if there is some drug in the urine, if the line is present, the urine does not have the MINIMUM amount of drug needed to consider it positive, so it is considered negative. it is possible that a faint test line on a rapid drug screen test is the result of the presence of “some” of the drug in the urine specimen (particularly in the case of THC). if this is the case, the concentration of the drug is very likely below the cutoff level of the test, which indicates a negative result. given the number of other factors which could cause faint test lines, it’s best to not over-interpret light test lines as containing some drug and just remember that the presence of a test line, regardless of how faint or "dark," indicates a negative result for that drug.

Court drug tests use numbers, and not lines. If you did drugs before you went on probation let them know you're going to fail the test BEFORE you take the test. If you wait until after the test is failed you lose all credibility.
