Probation and Parole - As introduced, specifies that if the trial judge finds by a preponderance of the evidence that the defendant has violated conditions of probation and suspension of sentence for a felony offense by engaging in conduct that constitutes a drug offense, then for the first instance of such a violation, the trial judge must order the defendant to attend a substance abuse treatment program and must not revoke the defendant's probation and suspension of sentence. - Amends TCA Title 40, Chapter 35.
