            0.08% or more blood alcohol concentration (BAC) level at the  
            time of driving the vehicle if his or her BAC level is 0.08%  
            at a chemical test performed within three hours after the  
            driving.  (Veh. Code, § 23152.)

          11)Provides that in a prosecution for DUI, it is a presumption  
            affecting the burden of proof that if the person had 0.05%, by  
            weight, of alcohol in his or her blood, it shall be presumed  
            that the person was not under the influence of an alcoholic  
            beverage at the time of the alleged offense.  (Veh. Code, §  
            23610 subd. (a)(1).)

          12)States that if there was, at that time, 0.05% or more but  
            less than 0.08%, by weight, of alcohol in the person's blood,  
            it shall be presumed that the person was not under the  
            influence of an alcoholic beverage, but the fact may be  
            considered with other competent evidence in determining  
            whether the person was under the influence of an alcoholic  
            beverage at the time of the alleged offense.  (Veh. Code, §  
            23610 subd. (a)(2).)

            beverage at the time of the alleged offense.  (Veh. Code, §  
            23610 subd. (a)(3).)

            blood-alcohol concentration was less than 0.20%, by weight, to  
            participate for at least three months or longer, as ordered by

          16)States that the court shall refer a first offender whose  
            blood-alcohol concentration was 0.20% or more, by weight, or  
            who refused to take a chemical test, to participate for at  
            least six months or longer, as ordered by the court, in a  
            licensed program that consists of at least 45 hours of program  
            activities, including those education, group counseling, and  
            individual interview sessions described by law.  (Veh. Code, §  
            23538 subd. (b)(2).)

          17)States that the court shall order a person to participate in  
            an alcohol and drug problem assessment program pursuant to

                                                                  Page E

           1)Author's Statement  :  According to the author, "AB 2500  
            provides law enforcement tool to combat drugged driving by  
            enacting a per se standard prohibiting a person from driving  
            while under the influence of illegal drugs.

            "Drugged driving has been increasing at an alarming rate.  The  
            Office of Traffic Safety (OTS) recently released a study  
            indicating that nearly twice as many California drivers, 14%  
            versus 7.3%, tested positive for drugs that may impair driving  
            abilities than did for alcohol.  Of those tested positive for  
            alcohol, 23% tested positive for at least one other drug as  
            well.

            "The Institute for Behavior and Health conservatively  
            estimates that 20% of all vehicular crashes in the United  
            States are caused by drugged driving.  This translates into  
            over 6,700 deaths, 440,000 injuries and nearly $60 billion in  
            costs annually.

            "National roadside safety studies have revealed that drugs  
            were present more than seven times as frequently as alcohol  
            among weekend nighttime drivers, with over 16% testing  
            positive for drugs versus only 2% being at or above the legal  
            limit for alcohol.  Further, Trauma room studies have shown  
            that 51% of patients tested positive for illegal drugs,  
            compared to 34% who tested positive for alcohol.

            "The enactment of a per se standard for drugged driving has  
            been identified as one of the major initiatives of the Obama  
            Administration's 2010 National Drug Control Strategy.  In  
            fact, federal Department of Transportation regulations have  
            required a per se standard on commercial drivers since 1988.

            "Currently, 17 states (Arizona, Delaware, Georgia, Indiana,  
            Illinois, Iowa, Michigan, Minnesota, Nevada, North Carolina,  
            Ohio, Pennsylvania, Rhode Island, South Dakota, Utah, Virginia  
            and Wisconsin) have established a per se type of standard for  
            drugged driving."

           2)Conflicting Evidence on Per Se Standards for Driving Under the  
            Influence of Drugs  :  Under existing law, if a person's driving  
            is impaired by being under the influence of a drug, he or she  
            can be arrested and charged under Vehicle Code Section  
            23152(a).  A preliminary alcohol screening test is not  









                                                                  AB 2500
                                                                  Page F

            determinative of blood alcohol content, but is a field  
            sobriety test which may be used as a further investigative  
            tool in order to establish reasonable cause to believe a  
            person was driving a vehicle while under the influence of  
            alcohol.  (See Vehicle Code § 23612 subd. (h).)  If the  
            officer decides to use the preliminary alcohol screening test,  
            the officer shall advise the person that he or she is being  
            asked to take the test to assist the officer in determining if  
            he or she is under the influence of alcohol or drugs, or a  
            combination of alcohol and drugs.  The person's obligation to  
            submit to a chemical analysis of his or her blood, breath, or  
            urine is not satisfied by the person submitting to a  
            preliminary alcohol screening test.  (Veh. Code § 23612 subd.  
            (i).)  

          If the preliminary alcohol screening test indicates that there  
            is no alcohol present, this may be an indicator of driving  
            under the influence of drugs, taken together with other  
            factors which provided the peace officer with the reasonable  
            cause to stop the driver, such as erratic driving, failure of  
            other field sobriety tests, etc.  The existing law provides  
            that a person who chose a breath test may also be requested to  
            submit to a blood or urine test if the officer has reasonable  
            cause to believe that the person was driving under the  
            influence of a drug, or under the combined influence of  
            alcohol and a drug, and if the officer has a clear indication  
            that a blood or urine test will reveal evidence of the person  
            being under the influence.  (Vehicle Code § 23612 subd.  
            (a)(2)(C).)  That section also requires the officer to state  
            in his or her report the facts upon which that belief and  
            clear indication are based.  

          Although existing law provides the opportunity to obtain a blood  
            or urine test that will reveal if the person is under the  
            influence of drugs or under the combined influence of alcohol  
            or drugs, the bill's sponsor has stated that law enforcement  
            experiences significant difficulty obtaining filings or  
            prosecutions in cases in which the driver had detectable  
            amounts of drugs in his or her system, but did not have the  
            requisite 0.08% blood alcohol concentration in conjunction  
            with the drugs.  

            This bill seeks to change the standards for determining  
            whether a driver was under the influence at the time he or she  









                                                                  AB 2500
                                                                  Page G

            was pulled over by a law enforcement standard.  The new  
            standards would be a variety of per se amounts of specified  
            drugs.  This means that if a driver was operating a motor  
            vehicle with the specified amount of a specified drug in their  
            system they would be automatically determined as driving under  
            the influence, regardless of the observations of the officer,  
            the quality of their driving, or their performance on a field  
            sobriety test.  

            This bill prescribes the following per se amounts as a  
            violation of driving under the influence of these specified  
            drugs:  

              Amphetamine in the amount of 100 nanograms, or more, per  
            milliliter of whole blood;

              Cocaine in the amount of 50 nanograms, or more, per  
            milliliter of whole blood;

               Cocaine metabolite in the amount of 50 nanograms, or more,  
               per milliliter of whole blood;

               Delta-9-tetrahydrocannabinol of marijuana in the amount of  
               2 nanograms, or more, per milliliter of whole blood;

               Heroin in the amount of 50 nanograms, or more, per  
               milliliter of whole blood;

               Heroin metabolite 6-monoacetylmorphine in the amount of 10  
               nanograms, or more, per milliliter of whole blood;

               Methamphetamine in the amount of 100 nanograms, or more,  
               per milliliter of whole blood;

               Morphine in the amount of 50 nanograms, or more, per  
               milliliter of whole blood; or

               Phencyclidine in the amount of 10 nanograms, or more, per  
               milliliter of whole blood.
             
             Previous bills on this issue have sought to ban the presence  
            of any measurable amount of any of these substances in the  
            system of a driver at the time they are pulled over by law  
            enforcement.  Proponents of this legislation argue that these  









                                                                  AB 2500
                                                                  Page H

            amounts are congruent with acceptable standards of impairment  
            while operating a motor vehicle.  Opponents argue that these  
            amounts are not indicative of impairment and may represent  
            residual amounts of narcotics in the system of drivers.  The  
            opponents object on the basis that these amounts may indicate  
            that the person used the specified substance, but that the per  
            se amounts do not indicate that a person was under the  
            influence.  Proponents counter that it is too difficult to  
            convict a person of drugged driving if law enforcement has to  
            prove that the defendant is under the influence based on  
            observations (including observed driving), field sobriety  
            tests, and chemical tests.  They would prefer that the  
            chemical tests stand alone, and that a conviction should  
            result if a specified drug is present at a specified level in  
            the system of the driver.     

           3)Office of National Drug Control Policy Drugged Driving Fact  
            Sheet  :  The sponsor of this bill provided a fact sheet from  
            the Office of Drug Control Policy, dated December of 2012.   
            According to the report, "[d]rugged driving poses threats to  
            public safety, as evidenced by the number of fatal crashes  
            each year on our highways. Law enforcement officials see the  
            tragedies that too often result when people take drugs and  
            drive. Fortunately, trained Drug Recognition Experts can help  
            to identify drugged drivers and make our roadways safer.   
            Research demonstrates that drugs, even those prescribed by a  
            physician, can impair perception, judgment, motor skills, and  
            memory - critical skills for safe and responsible driving.  
            Recent surveys have shown how pervasive drugged driving has  
            become in the United States.  The Obama Administration  
            recognizes the seriousness of the issue and is taking steps to  
            reduce drugged driving. For example, President Obama has drawn  
            much-needed attention to the issue of drugged driving by  
            declaring December National Impaired Driving Prevention Month  
            in 2010, 2011, and 2012. The President's goal is to reduce  
            drugged driving by 10 percent by 2015. To reach this mark, the  
            Administration is working to advance initiatives to improve  
            public awareness, enhance law enforcement training, improve  
            screening methodologies, and collect more comprehensive data  
            to support effective policy-making."

           4)The Time it Takes for a Drug to Be Eliminated from the System:   
             According to a report issued by the United Nations Office on  
            Drugs and Crime:









                                                                  AB 2500
                                                                  Page I


               Drugs vary by their elimination half-lives, which is  
               the time required for the blood levels to decline by  
               50%.  The half-life of a drug is heavily influenced by  
               a variety of factors, including the individual's age,  
               sex, physical condition and clinical status.  A  
               compromised liver and the concurrent presence of  
               another disease or drug have the potential of enhancing  
               the toxic effects of the drug by slowing down the  
               elimination process.  Under different clinical  
               conditions, however, the process may be speeded up.   
               Therefore, great variation may be found in the  
               half-lives of the same drug. 

               Approximately six half-lives are required to eliminate  
               99% of any drug.  Because the half-life of cocaine is  
               relatively short, averaging one hour, only six hours  
               are needed for the elimination of 99% of the drug.   
               Cocaine metabolites have a longer half-life and can be  
               detected for a considerably longer period of time  
               through urine drug assays.  Compared with cocaine,  
               phenobarbital has a much longer half-life (80 to 120  
               hours), so that at least 480 hours, or 20 days, are  
               required to eliminate 99% of the drug.  Since there is  
               much variation in the half-lives of different drugs and  
               the absolute amount of drug present can be very small,  
               it is crucial that the appropriate body fluid for  
               analysis is selected for testing. 

               Elimination of ethanol [alcohol] follows a different  
               pattern.  Its levels decline almost linearly over time.  
                The average elimination rate is between 15 mg/100 ml  
               and 20 mg/100 ml (0.015-0.02 per cent) per hour,  
               although rates of between 10 mg/100 ml and 30 mg/100 ml  
               (0.01-0.03 per cent) per hour have also been observed.   
               In the alcoholic patient, the elimination rate is  
               generally higher.  In forensic calculations, a rate of  
               15 mg/100 ml (0.015%) per hour is usually used.   
               (http://www.unodc.org/unodc/en/data-and-analysis/bulleti 
               n/bulletin_1993-01-01_2_page005.html)

           5)Can Per Se Limits Determine Impairment at the Time of  
            Driving?  :   Opponents' most persuasive arguments are that per  
            se limits do not indicate that a driver is actually under the  









                                                                  AB 2500
                                                                  Page J

            influence at the time they are operating a vehicle.  If a  
            defendant is to be punished for driving under the influence,  
            they should actually be under the influence at the time of the  
            alleged offense.  Otherwise, drivers are merely being  
            convicted of driving under the influence for having ingested a  
            substance (legally or illegally) at some point prior to  
            driving.  

            According to a 2011 National Highway Transportation and Safety  
            Administration, Drug Recognition Expert Training Manual<1>,  
            "Toxicology has some important limitations. One limitation is  
            that, with the exception of alcohol, toxicology cannot produce  
            'per se' proof of drug impairment. That is, the chemist can't  
            analyze the blood or urine and come up with a number that  
            "proves" the person was or wasn't impaired." As the bill  
            relates to the presence of THC (marijuana) in the system of a  
            driver, "It is difficult to establish a relationship between a  
            person's THC blood or plasma concentration and performance  
            impairing effects. It is inadvisable to try and predict  
            effects based on blood THC concentrations alone, and currently  
            impossible to predict specific effects based on THC-COOH  
            concentrations<2>." 

            The presence of drugs in the system of a driver is not a good  
            fact.  However, under current law that evidence can be used to  
            argue that a driver was under the influence at the time they  
            drove a vehicle.  This bill would state that a person is in  
            fact guilty if they have the proscribed amounts in their  
            system at the time they were driving.  The science appears  
            conflicted on this issue and it is not clear that a driver  
            would necessarily be guilty at these levels.  In fact, many  
            proponents have argued for a 5 nanograms standard for driving  
            under the influence of marijuana.  The states that do have per  
            se limits are inconsistent on the standards set.  The 2  
            nanogram limit proposed in this bill is legislation is on the  
            low end of those five states have set numerical limits.  Other  
            states have adopted zero tolerance standards which permit no  
            measurable amount in the system, but that is not the approach  
                                                                                  --------------------------

            of this bill.  

          6)Standard of Proof  :  "For a defendant to be guilty of driving  
            while under the influence of drugs in violation of Vehicle  
            Code Section 23152(a), 'the drug(s) must have so far affected  
            the nervous system, the brain, or the muscles of the  
            individual as to impair to an appreciable degree the ability  
            to operate a motor vehicle in a manner like that of an  
            ordinarily prudent and cautious person in full possession of  
            his or her faculties," citing  People v. Enriquez  , 42 Cal. App.  
            4th at p. 665; Gilbert v. Municipal Court, 73 Cal. App. 3d at  
            p. 727.  "Driving while under the influence of drugs involves  
            a greater degree of impairment of an individual's faculties,  
            and in that respect is not similar to merely being under the  
            influence of drugs."  [  People v. Canty  , 32 Cal. 4th 1266  
            (2004).]

          This bill, in establishing a "per se" standard that would  
            presume a person was under the influence if he or she had a  
            specified amount of a drug, in his or her system, would  
            effectively abolish the standard of proof set forth in the  
            above-cited cases.  Is it reasonable to presume that a person  
            is in violation of the law prohibiting driving under the  
            influence of drugs if the drugs have not "impaired to an  
            appreciable degree the ability to operate a motor vehicle in a  
            manner like that of an ordinarily prudent and cautious person  
            in full possession of his or her faculties?"  (  Canty,  supra.)  
           
           7)No Exceptions for Prescription Medications  :  This bill fails  
            to include any exception for the ingestion of prescription  
            medications.  Opponents of this legislation have indicated  
            that people who use marijuana medicinally and at heavier  
            levels can have much higher THC levels than 2 nanograms and  
            that they are not under the influence.  These measurements are  
            the residual effects of medicinal use.  Perhaps the author  
            should consider an exception to the per se requirements for  
            holders of prescriptions.  Those drivers could still be  
            convicted of driving under the influence under the current  
            system of enforcement, based on a totality of the  
            circumstances (officer's observations, observed driving, field  
            sobriety tests, and chemical tests).  

           8)Approved Medical Uses of Amphetamines  :  "Amphetamines and  
            amphetamine congeners are a large group of chemically related

                                                                  Page L

            central stimulant drugs; among the best known are  
            dextroamphetamine (Dexedrine), methamphetamine (Methedrine)  
            and methylphenidate (Ritalin). Amphetamines continue to be  
            prescribed to treat attention deficit disorders in both  
            children and adults.  Hyperactive children do not usually  
            outgrow their problems, although the symptoms may change.  In  
            adolescence they are often academic underachievers with poor  
            social skills and low self-esteem, who may become juvenile  
            delinquents.  Many of the symptoms also persist in adult  
            life."  [Lester Grinspoon and James B. Bakalar,  Medical Uses  
            of Illicit Drugs  , Schaffer Library of Drug Policy.

          hemp/medical/meduse.htm.]  

          That article also states "today, cocaine is used in medicine  
            mainly as a topical analgesic in eye, ear, nose, and throat  
            surgery and fiber tube optical examinations of the upper  
            respiratory and digestive tracts.  It has a combination of  
            properties that cannot be duplicated by any of the synthetic  
            local anesthetics:  intense constriction of blood vessels  
            (important whenever bleeding must be prevented), long duration  
            of anesthesia (one hour), and low toxicity.  [L]egally, the  
            coca leaf and all its derivatives containing cocaine are  
            classified under Schedule II of the Controlled Substances Act.  
             Amphetamines and related drugs continue to be the drug  
            treatment of choice in the treatment of narcolepsy, a disorder  
            marked by an uncontrollable desire for sleep or sudden attacks  
            of sleep during the daytime.  It usually begins in adolescence  
            and never completely remits.  Dextroamphetamine or  
            methylphenidate may be necessary for a narcoleptic person  
            whose work is dangerous but most victims of narcolepsy can  
            perform satisfactorily without drugs if they take at least one  
            nap a day."   
            [http://www.druglibrary.org/schaffer/hemp/medical/meduse.htm.]

          It appears from the above authorities that not only are there  
            approved medical uses for two of the three drugs covered by  
            this bill, one of the drugs, amphetamines, are currently being  
            prescribed in large numbers to treat ADHD and, to a lesser  
            extent, narcolepsy.  Although preeminent in children and  
            adolescents, ADHD can continue into adulthood, requiring  
            continued prescription of Ritalin and related drugs.

           9)Argument in Support  :  According to the  California Police  
            Chiefs Association  , "AB 2500 will finally give law enforcement  
            a tool to effectively combat drugged driving.  The bill will  
            create a per se standard which will prohibit drivers from  
            being behind the wheel of their automobile with any detectable  
            amount of controlled substances in their system, or, in the  
            case of marijuana, any detectable amount of Delta IX THC in  
            the driver's system.  
             
             "Enactment of a per se standard for drugged driving has been  
            identified by the Obama Administration's 2010 National Drug  
            Control Strategy as one of its major initiatives.  Moreover,  
            federal Department of Transportation regulations have required  
            a per se standard on commercial drivers since 1988.  There is  
            no rational reason not to require all drivers to operate under  
            a drugged driving per se standard.  

            "Drugged driving has been increasing in California.  The  
            Office of Traffic Safety (OTS) recently released a study that  
            found more California drivers tested positive for drugs that  
            impair driving (14 percent) than did for alcohol (7.3  
            percent).  Positive tests for marijuana were most prevalent,  
            at 7.4 percent.  Of those testing positive for alcohol, 23  
            percent also tested positive for at least one other drug.   
            When drivers combine alcohol and drug use the impairing  
            effects of both substances can be increased."

          10)                           Argument in Opposition:   According  
            to  California NORML  , "We wish to reiterate our opposition to  
            AB 2500 (Frazier) as amended, which would criminalize driving  
            with specified trace levels of marijuana or other controlled  
            substances in one's blood regardless of actual impairment.    
            As documented in the appendix below, the government's own  
            experts acknowledge that there exists no scientific basis for  
            determining driving impairment from levels of THC or other  
            controlled substances in the blood.
             
             "In specific, with regards to the proposed per se DUI standard  









                                                                  AB 2500
                                                                  Page N

            of 2 nanograms/milliliter THC in blood, the science is clear  
            that such levels do not constitute impaired driving.  Blood  
            levels above 2 ng/ml have been detected for as long as six  
            days after last use in chronic users,  far longer than the  
            measurable impairment period of 2.5 - 4 hours.  As a result,  
            AB 2500 will wrongly criminalize countless non-impaired  
            drivers as DUI.   

            "Unlike alcohol, the blood level of marijuana's major active  
            constituent, THC,  has no direct relation to the actual dosage  
            consumed or active in the body. Instead, it reflects recency  
            of use, spiking to high levels immediately after smoking then  
            declining quickly to lower levels within an hour or so  
            regardless of dosage.  Like alcohol, for which non-zero blood  
            levels are permitted under California law, THC can occur at  
            low concentrations with no adverse impact on driving.  Unlike  
            alcohol, THC can remain detectable in the blood for hours and  
            days after last use, long after any impairment has faded.    
            Regular users tend to develop tolerance to THC impairment,  
            allowing them to drive safely.  Medical users have even  
            manifested improved driving skills with THC levels as high as  
            71 ng/ml THC in blood. 

            "Numerous studies  have found no higher accident risks in  
            drivers with THC in blood;  some have even reported lower  
            risks, perhaps because marijuana induces more cautious  
            driving. Studies of driving accidents have consistently found  
            that marijuana poses a significantly lesser hazard than  
            alcohol and other drugs, such as prescription narcotics.    
            Studies have variously estimated that THC-positive drivers  
            have a 1.2 - 2.3 times higher average statistical risk for  
            accidents, less than drivers with low, legal amounts of  
            alcohol. These risks are uneven for different drivers and far  
            less than those for alcohol at the legal limit (4.5 - 8.5   
            times).   Thus, AB 2500 irrationally punishes marijuana more  
            harshly than alcohol and other, more dangerous drugs.  

            "Government experts agree that there is no clear, per se  
            threshold for driving impairment.   According to the U.S  
            National Highway Traffic Safety Administration it is  
            "inadvisable to try and predict effects based on blood THC  
            concentrations alone," as "concentrations of parent drug and  
            metabolite are very dependent on pattern of use as well as  
            dose."   See Appendix below.

                                                                  Page O


            "We note that similar consideration apply to the other  
            controlled substances covered in AB 2500.  Alcohol is unique  
            in being the only drug for which blood concentrations have  
            been shown to offer a clear threshold for impairment.  AB 2500  
            would therefore wrongly criminalize countless non-impaired  
            drivers with trace amounts of other drugs, including some  
            legally prescribable narcotics.   

            "There is no evidence of a drug DUI crisis in California.    
            California ranks among the top states in the nation with  
            regards to highway safety.   Even while the availability of  
            medical marijuana has expanded, California's  highway fatality  
            rate  has continued to post record lows in recent years.   
            Neither has there been any surge in DUIs, arrests for which  
            have declined by 5% from 2003 to 2012.  California prosecutors  
            currently enjoy a 79% conviction rate for DUI, up  
            substantially from 64% since 1989.     

            "California's present DUI law is sound.  The law properly  
            allows drug tests to be considered along with other relevant  
            evidence in determining whether a driver is DUI. A study of  
            states that have adopted per se drugged driving laws found "no  
            evidence that they reduce driving fatalities."  If California  
            is interested in better detection of drug-impaired driving, it  
            should consider performance tests that measure actual  
            impairment, rather than chemical residues in the system.  

            "In 2012, the Governor signed AB 2552 to collect better  
            statistics on drug DUI arrests in California.  These data  
            ought to be tracked and assessed before enacting any new drug  
            DUI legislation.  Likewise the federal government is currently  
            assessing drug DUI policy;  until this is completed, it would  
            be premature to revise California's current laws.

            "In sum, AB 2500 will wrongly criminalize thousands of  
            unimpaired drivers, including many seriously ill medical  
            cannabis patients;  significantly increase the cost of DUI  
            enforcement;   put innocent drivers at risk of blood testing;   
             and do nothing to improve highway safety."

               zero tolerance for drugged driving per se standard.  SB 289  
               failed passage in Senate Public Safety Committee.  

             b)   AB 2552 (Torres),  Chapter 753, Statutes of 2012, was  
               originally a zero tolerance for drugged driving per se  
               standard bill but was amended in the Assembly to modify the  
               penal code to allow the tracking of charges for drugged  
               driving as distinguished from driving under the influence  
               of alcohol.  

             c)   AB 1215 (Benoit), 2007-2008 legislative session, created  
               a zero tolerance for drugged driving per se standard.    AB  
               1215 failed Assembly Public Safety.
