(a) (1) In any criminal prosecution for a violation of this chapter or Ohio R.C. Chapters 2925 or 3719, a laboratory report from the Bureau of Criminal Identification and Investigation or a laboratory operated by another law enforcement agency, or a laboratory established by or under the authority of an institution of higher education that has its main campus in this state and that is accredited by the Association of American Universities or the North Central Association of Colleges and Secondary Schools, primarily for the purpose of providing scientific service to law enforcement agencies, and signed by the person performing the analysis, stating that the substance that is the basis of the alleged offense has been weighed and analyzed and stating the findings as to the content, weight, and identity of the substance and that it contains any amount of a controlled substance and the number and description of unit dosages, is prima facie evidence of the content, identity, and weight or the existence and number of unit dosages of the substance. In any criminal prosecution for a violation of Ohio R.C. 2925.041 or a violation of this chapter, Ohio R.C. Chapter 2925 or Ohio R.C. Chapter 3719 that is based on the possession of chemicals sufficient to produce a compound, mixture, preparation, or substance included in Schedule I, II, III, IV, or V, a laboratory report from the Bureau or from any laboratory that is operated or established as described in this subsection that is signed by the person performing the analysis, stating that the substances that are the basis of the alleged offense have been weighed and analyzed and stating the findings as to the content, weight, and identity of each of the substances, is prima facie evidence of the content, identity, and weight of the substances.
(2) Attached to that report shall be a copy of a notarized statement by the signer of the report giving the name of the signer and stating that the signer is an employee of the laboratory issuing the report and that performing the analysis is a part of the signer’s regular duties, and giving an outline of the signer’s education, training, and experience for performing an analysis of materials included under this section. The signer shall attest that scientifically accepted tests were performed with due caution, and that the evidence was handled in accordance with established and accepted procedures while in the custody of the laboratory.
(b) The prosecuting attorney shall serve a copy of the report on the attorney of record for the accused, or on the accused if the accused has no attorney, prior to any proceeding in which the report is to be used against the accused other than at a preliminary hearing or grand jury proceeding where the report may be used without having been previously served upon the accused.
(c) The report shall not be prima facie evidence of the contents, identity, and weight or the existence and number of unit dosages of the substance if the accused or the accused’s attorney demands the testimony of the person signing the report, by serving the demand upon the prosecuting attorney, within seven days from the accused or the accused’s attorney’s receipt of the report. The time may be extended by a trial judge in the interests of justice.
(d) Any report issued for use under this section shall contain notice of the right of the accused to demand, and the manner in which the accused shall demand, the testimony of the person signing the report.
(e) Any person who is accused of a violation of this chapter or Ohio R.C. Chapters 2925 or 3719 is entitled, upon written request made to the prosecuting attorney, to have a portion of the substance that is, or of each of the substances that are, the basis of the alleged violation preserved for the benefit of independent analysis performed by a laboratory analyst employed by the accused person, or, if the accused is indigent, by a qualified laboratory analyst appointed by the court. Such portion shall be a representative sample of the entire substance that is, or of each of the substances that are, the basis of the alleged violation and shall be of sufficient size, in the opinion of the court, to permit the accused’s analyst to make a thorough scientific analysis concerning the identity of the substance or substances. The prosecuting attorney shall provide the accused’s analyst with the sample portion at least 14 days prior to trial, unless the trial is to be held in a court not of record or unless the accused person is charged with a minor misdemeanor, in which case the prosecuting attorney shall provide the accused’s analyst with the sample portion at least three days prior to trial. If the prosecuting attorney determines that such a sample portion cannot be preserved and given to the accused’s analyst, the prosecuting attorney shall so inform the accused person, or the accused’s attorney. In such a circumstance, the accused person is entitled, upon written request made to the prosecuting attorney, to have the accused’s privately employed or court appointed analyst present at an analysis of the substance that is, or the substances that are, the basis of the alleged violation, and, upon further written request, to receive copies of all recorded scientific data that result from the analysis and that can be used by an analyst in arriving at conclusions, findings, or opinions concerning the identity of the substance or substances subject to the analysis.
(f) (1) In addition to the rights provided under subsection (e) of this section, any person who is accused of a violation of this chapter or Ohio R.C. Chapters 2925 or 3719 that involves a bulk amount of a controlled substance, or any multiple thereof, or who is accused of a violation of Ohio R.C. 2925.11 or a substantially equivalent municipal ordinance, other than a minor misdemeanor violation, that involves marihuana, is entitled, upon written request made to the prosecuting attorney, to have a laboratory analyst of the accused’s choice, or, if the accused is indigent, a qualified laboratory analyst appointed by the court, present at a measurement or weighing of the substance that is the basis of the alleged violation.
(2) Also, the accused person is entitled, upon further written request, to receive copies of all recorded scientific data that result from the measurement or weighing and that can be used by an analyst in arriving at conclusions, findings, or opinions concerning the weight, volume or number of unit doses of the substance subject to the measurement or weighing.

(g) In addition to the financial sanctions authorized or required under Ohio R.C. 2929.18 and 2929.28 and to any costs otherwise authorized or required under any provision of law, the court imposing sentence upon an offender who is convicted of or pleads guilty to a drug abuse offense may order the offender to pay to the state, municipal, or county law enforcement agencies that handled the investigation and prosecution all of the costs that the state, municipal corporation, or county reasonably incurred in having tests performed under this section or Ohio R.C. 2925.51 or in any other manner on any substance that was the basis of, or involved in, the offense to determine whether the substance contained any amount of a controlled substance if the results of the tests indicate that the substance tested contained any controlled substance. No court shall order an offender under this section to pay the costs of tests performed on a substance if the results of the tests do not indicate that the substance tested contained any controlled substance. The court shall hold a hearing to determine the amount of costs to be imposed under this section. The court may hold the hearing as part of the sentencing hearing for the offender.
