F.S. 790.157
790.157 Presumption of impairment; testing methods.
(1) It is unlawful and punishable as provided in s. 790.151 for any person who is under the influence of alcoholic beverages or controlled substances, when affected to the extent that his or her normal faculties are impaired, to use a firearm in this state.
(2) Upon the trial of any civil or criminal action or proceeding arising out of acts alleged to have been committed by any person while using a firearm while under the influence of alcoholic beverages or controlled substances, when affected to the extent that his or her normal faculties were impaired or to the extent that the person was deprived of full possession of his or her normal faculties, the results of any test administered in accordance with s. 790.153 or s. 790.155 and this section shall be admissible into evidence when otherwise admissible, and the amount of alcohol in the person’s blood at the time alleged, as shown by chemical analysis of the person’s blood or chemical or physical analysis of the person’s breath, shall give rise to the following presumptions:
(a) If there was at that time 0.05 percent or less by weight of alcohol in the person’s blood, it shall be presumed that the person was not under the influence of alcoholic beverages to the extent that his or her normal faculties were impaired.
(b) If there was at that time in excess of 0.05 percent but less than 0.10 percent by weight of alcohol in the person’s blood, such fact shall not give rise to any presumption that the person was or was not under the influence of alcoholic beverages to the extent that his or her normal faculties were impaired, but such fact may be considered with other competent evidence in determining whether the person was under the influence of alcoholic beverages to the extent that his or her normal faculties were impaired.
(c) If there was at that time 0.10 percent or more by weight of alcohol in the person’s blood, that fact shall be prima facie evidence that the person was under the influence of alcoholic beverages to the extent that his or her normal faculties were impaired.

The percent by weight of alcohol in the blood shall be based upon grams of alcohol per 100 milliliters of blood. The foregoing provisions of this subsection shall not be construed as limiting the introduction of any other competent evidence bearing upon the question of whether the person was under the influence of alcoholic beverages to the extent that his or her normal faculties were impaired.

(3) A chemical analysis of a person’s blood to determine its alcoholic content or a chemical or physical analysis of a person’s breath, in order to be considered valid under the provisions of this section, must have been performed substantially in accordance with methods approved by the Florida Department of Law Enforcement and by an individual possessing a valid permit issued by the department for this purpose. Any insubstantial differences between approved techniques and actual testing procedures in an individual case shall not render the test or test results invalid. The Florida Department of Law Enforcement may approve satisfactory techniques or methods, ascertain the qualification and competence of individuals to conduct such analyses, and issue permits which shall be subject to termination or revocation in accordance with rules adopted by the department.
(4) Any person charged with using a firearm while under the influence of alcoholic beverages or controlled substances to the extent that his or her normal faculties were impaired, whether in a municipality or not, shall be entitled to trial by jury according to the Florida Rules of Criminal Procedure.
