San Diego Marijuana DUIs will now be prosecuted even more with the new law making marijuana legal. This means marijuana is going to be legal for those 21 and over.
However, like alcohol, having too much while behind the wheel can find you in some trouble.
The issue is going to be how much is too much. With alcohol, we know that .08% or greater will get you in trouble. But how much is too much for marijuana? That limit is likely to be made soon. In the meantime, it is going to be a combination of active marijuana in the system, coupled with impaired symptoms and bad driving.

People arrested for driving with marijuana in their system often pose no danger to the public, unlike drivers with alcohol and other drugs. Indeed, studies have shown that drivers that have ingested pot responsibly can drive safely, in some cases better than those who have not. As the science gets established, there seems to be an agenda to push forward with prosecutions. If you are arrested for a marijuana DUI, contact the Law Offices of Mark Deniz at (858) 751-4384.
Driving Under the Influence of Marijuana
Driving under the influence of any drug is a crime. This includes not only illegal narcotics, but also prescription medication, prescribed marijuana, and on some occasions, even over the counter medications. The crime is often referred to as DUI drugs, DUID, drugged driving, driving under the influence of marijuana or any combination of drugs.
Vehicle Code section 23152(f) and (g) state this offense has the same consequences as driving under the influence of alcohol. The law indicates the following:
• It is unlawful for a person who is under the influence of any drug to drive a vehicle.
• It is unlawful for a person who is under the combined influence of any alcoholic beverage and drug to drive a vehicle.
Driving both under the influence of drugs and driving under the influence of alcohol are very similar. It affects your nervous system in a way where you are impaired and you are in an altered state of consciousness. However, there are significant differences between the two offenses when being charged.
California Vehicle Code section 23152(a) & (b) state that it is illegal to drive under the influence of alcohol, and to drive with a blood alcohol concentration of .08% or more. California law does not specifically prescribe a prohibition on the amount of a given drug. Whether it be a prescription medication, marijuana, or controlled substance, California law does not actually prohibit a certain amount of a given drug in a person’s system. Rather, the law simply prohibits a person from “driving under the influence” of a drug. In order for a person to be considered “driving under the influence” of a drug, it must have such an effect on a person so that their mental or physical abilities are so impaired that he or she is no longer able to drive a vehicle with the caution of a sober person, using ordinary care, under similar circumstances.
Often times individuals who are suspected of DUID are put through the same or similar tests as are driver’s suspected of alcohol DUI. On most occasions, however, a “drug recognition expert” known as a “DRE” is usually called into the case when drugs are involved to examine the individual in question. A DRE is supposed to have special training related to identifying the symptomology of different types of drug use, and he/she can testify to the symptoms and effects of drugs or marijuana, and determine if the person is impaired in their opinion.
Important: A driver can be using marijuana or medication legally with a physician prescription, and yet if he or she is legally impaired, they can be charged with driving under the influence drugs according to CVC 23152(f). In fact, there are circumstances where sometimes over the counter products and medications, such as Benadryl or Nyquil, can be alleged to have caused a person to be “driving under the influence of a drug”.
In addition, a DUID Is very different from an alcohol-related DUI in terms of the potential consequences in the DMV. If a person is arrested because of an alcohol-related DUI, then the DMV can impose an “administrative suspension” on their license if the person refuses the chemical testing or if there is a BAC above .08%. Again, in DUID situations, there is no actual amount of drugs that can cause an “administrative suspension”. Therefore, the DMV cannot impose an administrative suspension due to any amount of drugs found in a person system, however, they can still impose a suspension if the person was valid arrested for a DUID and they refused chemical testing. (The DMV can also impose a separate suspension if a person is convicted of any DUI charge in criminal court.)
The chemical testing between DUI drugs and alcohol-related DUI also has some differences. Whereas law enforcement has the capability of testing for a person’s blood alcohol concentration (BAC) through the use of a breath test, such a test will not show the presence of marijuana or drugs (at this point – although technology and laws are quickly advancing). Consequently, testing for drugs has to be administered by taking a blood test.
Elements of the Offense
The offense of a San Diego DUI Marijuana case requires proof beyond a reasonable doubt of two elements:
• Driving a motor vehicle
• While under the influence of marijuana
Driving is usually proven through the testimony of the officer who observed the driving. However, in cases where the officer was not present, such as where there has been an accident or the car is parked, the driving element may be established through the testimony of passengers, witnesses, statements of the defendant, or – in some cases – through circumstantial evidence. This circumstantial evidence of driving under the influence of marijuana can consist of testimony that, for example, the defendant was seen behind the wheel of the parked car, the engine was warm, the keys were in the defendant’s pocket, etc. Circumstantial evidence is, of course, usually more susceptible to reasonable doubt in court than is direct evidence.
The second element in a San Diego DUI Marijuana case – the defendant was under the influence of marijuana while he was driving – requires proof of impairment, This is legally defined as being impaired to such an extent that he lacked the “ability to drive with the caution characteristic of a sober person of ordinary prudence under the same or similar circumstances.” This is, of course, a notoriously vague and subjective standard of proof.
Does Marijuana Cause Impairment?
Does marijuana in fact cause impairment of driving ability? There is substantial evidence that it does not. A review conducted in 2002 of seven separate studies of over 7,000 drivers involved in auto accidents concluded that, “Crash culpability studies have failed to demonstrate that drivers with cannabinoids in the blood are significantly more likely than drug-free dr
ivers to be culpable in road crashes”.
Two separate studies conducted by the U.S. Department of Transportation have reached similar conclusions. In one, researchers concluded that “although alcohol was found consistently and significantly to cause impairment, marijuana had only an occasional effect”. In the other study, researchers found that “THC is not a profoundly impairing drug…It apparently affects controlled information processing in a variety of laboratory tests, but not to the extent which is beyond the individual’s ability to control when he is motivated and permitted to so so in driving.”
The usual means of poving the required degree of impairment in a DUI marijuana case is through (1) such observations by the investigating officer as erratic driving, physical appearance, mental acuity, field sobriety tests, the presence of marijuana or paraphernalia in the car, and incriminating statements, and (2) analysis of the driver’s blood for THC (Tetrahedroncannabinol).
An increasingly common practice in DUI marijuana investigations is to call in a “drug recognition expert“, also called a “drug recognition evaluator” (DRE) – at the scene of the investigation or later at the police station or medical facility. This is an officer who has gone through a training program, originally created by the Los Angeles Police Department in the 1970s and later adopted by state and federal law enforecmentagencies nationwide. The program involves the use of a standardized DRE drug impairment protocol of observations and tests for the recognition of drug influence and impairment, including impariment caused by marijuana. The protocols have, however, been the subject of criticism, and the training, skills and abilities of individual DREs vary widely. In the end, the test is necessarily somewhat subjective and dependent upon the training, experience and accuracy of the officer.
The Blood Test
A driver who is arrested for driving under the influence is required by law to submit to breath or blood testing; refusal to do so can be punished by an increased jail term and a longer license suspension. Since marijuana cannot be detected on a breathalyzer, drivers suspected of DUI marijuana are required to submit to having a sample of blood drawn. The blood is then later tested by a laboratory for the presence of THC.
There are, however, periodic attempts to develop and use roadside tests for marijuana, just as hand-held breath alcohol tests were developed in recent years. The most recent of these DUI marijuana roadside tests have involved the investigating officer taking a swab of saliva from the driver’s mouth, and then using a device at the scene of the investigation to analyze the saliva for THC. And there are recurrent attempts to enact legislation in Sacramento to authorize this procedure. To date, these attempts have been unsuccessful. See, for example, “Roadside Oral Swab Tests Coming?”
The problem with testing the blood for marijuana or saliva, however, is simple: analysis can only determine the presence of THC in the blood – it cannot determine either (1) when it was consumed, or (2) whether the amount would have caused any impairment. Inactive elements of marijuana can stay in a person’s blood for days, even weeks – long past when it could have any effects on the driver. And it has never been conclusively clearly established how much marijuana can cause driving impairment – if it causes any impairment at all.
In other words, it is difficult to establish any connection between the THC in the blood sample and the degree of driving impairment (if any).
There are basically three defenses to a charge of driving under the influence of marijuana in California:
1. The defendant was not driving.
2. The defendant did not use marijuana.
3. The defendant used marijuana but was not impaired at the time of driving

Recreational marijuana use may now be legal in California, but it is still illegal to drive while high.
That was the message San Diego hoped to send Thursday night at a checkpoint targeting drivers who may have been under the influence of pot.
A DUI check point was set up off Mission Bay Drive, right by the Interstate-5 south bound ramp.
Thursday’s checkpoint is the second one to be set up since January 1st, when recreational marijuana became legal.
A device called the Drager 5000 will be used to fight impaired driving by using saliva swabs to test for drugs in an individual’s system.
San Diego police debuted the tool in March of last year.
Police said there many factors that go into a DUI arrest after some raised concerns that marijuana could be in their system and could test positive but not be impaired – since marijuana can stay in a person’s system for long period of time compared to alcohol.
The DUI check point was scheduled to start at 11 p.m., Thursday night and go to Friday at 3 a.m.
