(a) In any criminal prosecution for a violation of any of the provisions of this chapter, a laboratory report from the State Bureau of Criminal Identification and Investigation, 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 services to law enforcement agencies and signed by the person performing the analysis, stating that the substance which 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.
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 he or she is an employee of the laboratory issuing the report and that performing the analysis is a part of his or her regular duties, and giving an outline of his or her 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 he or she 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 his or her 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 his or her 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 any of the provisions of this chapter is entitled, upon written request made to the prosecuting attorney, to have a portion of the substance that is 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 he or she is indigent, by a qualified laboratory analyst appointed by the Court. Such portion shall be a representative sample of the entire substance that is 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. The prosecuting attorney shall provide the accused's analyst with the sample portion at least fourteen 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 his or her attorney. In such a circumstance, the accused person is entitled, upon written request made to the prosecuting attorney, to have his or her privately employed or Court appointed analyst present at an analysis of the substance that is 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 subject to the analysis.
(f) In addition to the rights provided under subsection (e) hereof, any person who is accused of a violation of any of the provisions of this chapter that involves a bulk amount of a controlled substance, or any multiple thereof, or who is accused of a violation of Section 624.03, 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 his or her 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. 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.
