If i took a home drug test for cocaine and passes will that sample pass at the lab also?

Depends on…: Whether lab uses same test or a different one that tests for Cocaine metabolites or is more sensitive than the home variety. Perhaps best to seek detox program so u don't have to worry about passing drug screen tests. Your pcp may b able to recommend some good programs.

Not for certain: In the lab the test is more sensitive than a kit bought at the store. The lab test might be able to find traces, even though you do not have enough in your blood to experience mental effects.
