(a)
For the purposes of this chapter, "nonadjudication" means that the court withholds adjudication of guilt and sentencing, either at the conclusion of a trial on the merits or upon the entry of a plea of guilt by a defendant, and places the defendant in a nonadjudication program conditioned upon the successful completion of the requirements imposed by the court under this subsection.
(b)

63-11-30

Failure to successfully complete a nonadjudication program subjects the person to adjudication of the charges against him and to imposition of all penalties previously withheld due to entrance into a nonadjudication program. The court shall immediately inform the commissioner of the conviction as required in Section
63-11-37

b.
If the court determines that the person violated this section by operating a vehicle when under the influence of a substance other than alcohol that has impaired the person's ability to operate a motor vehicle, including any drug or controlled substance which is unlawful to possess under the Mississippi Controlled Substances Law, the person must submit to a one-hundred-twenty-day period of a nonadjudication program that includes court-ordered drug testing at the person's own expense not less often than every thirty (30) days, during which time the person may drive if compliant with the terms of the program, or suffer a one-hundred-twenty-day suspension of the person's regular driver's license, during which time the person will not operate any vehicle.

The court shall retain jurisdiction over cases involving nonadjudication for a period of not more than two (2) years.
(e)
