(2) For each policy of workers' compensation insurance issued or renewed in the state on or after July 1, 1997, a five percent (5%) reduction in the premium for such policy may be granted by the insurer if the insured certifies to the insurer that it has established and maintains a drug-free workplace program that complies with the requirements of Sections 71-3-201 through 71-3-225.

(3) The premium discount provided by this section shall be applied to an insured's workers' compensation insurance pro rata as of the date of receipt of certification by the insurer.

(5) The insured's workers' compensation insurance policy shall be subject to an additional premium for the purposes of reimbursement of a previously granted premium discount if it is determined that such insured misrepresented the compliance of its drug-free workplace program within the provisions of Sections 71-3-201 through 71-3-225.

(6) The Workers' Compensation Commission shall be authorized to promulgate rules and regulations necessary for the implementation and enforcement of this section.
