The costs of prosecution and conviction of persons imprisoned in the adult correctional institutions shall be paid by the state, and the payment of those costs shall form no part of the sentence of convicts. Nothing in this section shall be construed so as to prevent the imposition of costs provided for in chapter 25 of this title. The cost of commitment shall be paid by the state except as otherwise provided by the general laws; provided, that persons imprisoned in the adult correctional institutions shall be responsible for any assessments made pursuant to § 23-1-3.
