What's going to happen? Testing positive or failing to take the test can be a probation violation, result in a jail sanction or possibly derail any deals you have in place. There is no way to know how long a certain drug stays in your system. Scroll down for the common guidelines.
Recently, judges have been drug testing defendants while facing probation violations and also before a plea is accepted by the court. Typically, this is okay for them to do because a defendant is "on probation" or the court makes a drug test a prerequisite for accepting an agreed plea. Either way it is in your best interest to be able to pass a drug test when going to court. The consequences include refusal to accept an agreed plea, jail time sanctions, and the raising of a bond amount that virtually guarantees the client will not be able to get out.
It is crucial to be honest with your attorney to be able to make decisions about how to proceed. Remember that failure to take the test is considered a positive test.
