SEC. 4. EVALUATION OF MEASURES TO TEST FOR MARIJUANA IMPAIRMENT.

    (a) Study.--
            (1) In general.--The Administrator of the National Highway 
        Traffic Safety Administration shall conduct scientific testing 
        to determine--
                    (A) the extent to which marijuana impairs an 
                individual's ability to drive a motor vehicle;
                    (B) how the magnitude of such impairment varies 
                among individuals depending on certain characteristics, 
                including age, sex, body mass index, health status, and 
                history of marijuana use;
                    (C) whether or not it is possible to reliably 
                determine whether and to what extent an individual is 
                cognitively or physically impaired by marijuana solely 
                by measuring the concentration of tetrahydrocannabinol 
                (in this subsection referred to as ``THC'') and 
                derivatives in the individual's bloodstream or saliva;
                    (D) the most accurate methods for law enforcement 
                officers to measure THC concentration in the body of an 
                individual who is suspected of marijuana-impaired 
                driving, including blood testing and oral fluid 
                testing;
                    (E) how the effectiveness of such testing methods 
                is compromised if there is a delay between when an 
                individual is pulled over on suspicion of impaired 
                driving and when the individual is subjected to a 
                physical test to determine the individual's level of 
                impairment; and
                    (F) the most accurate field sobriety tests to 
                determine the level of physical and cognitive 
                impairment of drivers who have ingested marijuana.
            (2) Nature of study.--The testing described in paragraph 
        (1) shall--
                    (A) include--
                            (i) laboratory experimentation that 
                        measures the impact of marijuana on the 
                        physical and cognitive performance areas 
                        involved in driving, such as reaction time, 
                        tracking, motor coordination, visual functions, 
                        divided attention, signal detection, 
                        concentration, and hazard perception; and
                            (ii) experimentation on a driving course or 
                        driving simulator (or both) that measures the 
                        impact of marijuana on driving performance; and
                    (B) be completed not later than 2 years after the 
                date of enactment of this Act.
            (3) Availability of marijuana to nhtsa for research 
        purposes.--Not later than 60 days after receiving a request for 
        research-grade marijuana from the Administrator, the National 
        Institute on Drug Abuse shall make marijuana available to the 
        Administrator in an amount sufficient for the Administrator to 
        carry out the requirements of this subsection. Such marijuana 
        shall be as similar as practicable in THC concentration to 
        marijuana typically sold at marijuana dispensaries in States in 
        which the use of marijuana is legal with or without medical 
        justification.
    (b) Report.--
            (1) In general.--Not later than 180 days after the date of 
        enactment of this Act, the Administrator shall issue a report 
        that--
                    (A) contains recommendations to States on how to 
                prevent marijuana-impaired driving, including--
                            (i) the most effective measures for 
                        determining marijuana impairment;
                            (ii) the most effective methods for testing 
                        for marijuana impairment at the roadside, 
                        including an analysis of the affordability and 
                        feasibility of such testing for State and local 
                        law enforcement agencies; and
                            (iii) strategies for addressing the dangers 
                        posed by drivers who are impaired 
                        simultaneously by marijuana and other 
                        substances such as alcohol and prescription 
                        opioid medications;
                    (B) incorporates the results of other available 
                cognitive, experimental, and epidemiological studies; 
                and
                    (C) summarizes any findings from the study 
                conducted under subsection (a) that are available at 
                the time of the report.
            (2) Publication.--The Administrator shall--
                    (A) make the report described in paragraph (1) 
                available without cost in an electronic, publicly 
                accessible format;
                    (B) publish updates to the report every 6 months to 
                account for further findings derived from the study 
                conducted under subsection (a) and other relevant 
                cognitive, experimental, and epidemiological research; 
                and
                    (C) make all raw statistical data derived from the 
                study conducted under subsection (a) available in an 
                electronic, publicly accessible format, which shall 
                be--
                            (i) made available without charge, license, 
                        or registration requirement;
                            (ii) capable of being searched and 
                        aggregated;
                            (iii) permitted to be downloaded, including

                        is completed and the entirety of the results of 
                        the study has been published.

Summary: Lucid Act of 2015 Makes eligible for federal-aid highway project grants a state whose law legalizes the possession or use of marijuana with or without medical justification only if that state: has in effect a law prohibiting an individual from driving or being in actual physical control of a motor vehicle while impaired by marijuana, and enforces that law using training and methods for determining cognitive or physical marijuana impairment. Exempts those states from specified administrative penalties. Revises the terms quot, driving while intoxicatedquot, and quot, driving under the influencequot. To accord with this Act. Subjects repeat offenders to minimum civil and criminal penalties for driving a motor vehicle while impaired by marijuana in those states. Directs the Administrator of the National Highway Traffic Safety Administration to: study through scientific testing the extent to which marijuana impairs an individual's ability to drive a motor vehicle. And issue a report, and make it available electronically to the public, with recommendations to states on how to prevent marijuana-impaired driving.
