I am a 1st time probationee in Travis County , Tx . I have been on probation for 4 months out of 12 for marijuana possession . I am pretty confident that I will fail this test coming up on Friday . Based on my no previous convictions ( other than traffic offences ) is it likely that my probation will be revoked ? Is it possible to see jail time for failing a U.A the fist time ? Im losing sleep over this and would love some feedback ! Thanks much
