As an additional condition of parole for all such offenses or violations, the Parole Authority shall require participation in and completion of an appropriate drug treatment program. Vocational training, family counseling and literacy training may be imposed as additional parole conditions.
The Parole Authority may require any person on parole who commits a nonviolent drug possession offense or violates any drug-related condition of parole, and who is reasonably able to do so, to contribute to the cost of his or her own placement in a drug treatment program.
Parole may be modified or revoked if the parole violation is proved.
