What must be done upon learning about an offender's positive drug test?

When learning about an offender's positive drug test, informing the sentencing authority is critical as it ensures that the relevant legal and institutional processes are upheld. The sentencing authority, which could be a judge or parole board, needs to be made aware of the offender's non-compliance with the conditions of their supervision or parole. This notification allows for appropriate legal actions to be taken, which may include considering a modification of the offender's sentence, revocation of probation, or other sanctions deemed necessary.

Ensuring that the sentencing authority is informed maintains the integrity of the criminal justice system and upholds the enforcement of rules and regulations regarding probation or parole conditions.
