If you violate parole, depending on the nature of the underlying offense and the severity of the violation, you are placed in one of three categories. For Category 1 violators, you usually face no-less than an additional 15 months’ incarceration. For Category 2 violators, you usually are mandated to take part in a prison drug treatment program such as WILLARD. This typically lasts 90 days. Finally, Category 3 violators, face three to six months in state prison. This time does not include the time already served.
