My bro used coke this morning on the 5th court on 10th.. its possible judge will drug test him.. he was clean for a week relapsed and did small doses the past 4 days will he pass what can he do?

It depends on the time line for when do the test. IE, is he shuttled off to get tested right away or if it is within a day/week. As well it is dependent on the test. If they're testing for habitual use then they'll do a hair sample, 90 days, inch and a half. Has he been a habitual user?

I would try to quit as quickly as possible, not just for the testing, but for general health reasons.
