DUI: Men vs. Women

Great news article from the Bellingham Herald discusses the physiological differences in alcohol impairment levels experienced between men and women.

In Who Gets Arrested More for DUI: Men or Women?,  author Doug Dahl states that over the past couple decades, alcohol-impaired driving has steadily been decreasing, however, the reduction in impaired driving doesn’t apply to women. Dahl is the Target Zero Manager for the Whatcom County Traffic Safety Task Force.

Apparently, in a recent 10-year period, DUI arrests for men decreased by 7.5 percent while DUI arrests for women increased by 28.8 percent.

“According to the CDC, the average weight of an American man is 196 pounds, while the average American woman weighs 166 pounds,” said Dahl.  “Also, because of differences in enzymes, hormones and body fat percentages between men and women, women generally metabolize alcohol at a slower rate.” Simply put, says Dahl, women get drunk faster and stay drunk longer than men:

“To be clear, both of our imaginary people in this example shouldn’t drive. A BAC of .06 will cause impairment. It’s a big enough concern that legislators in some states, including Washington, have proposed reducing the legal limit to .05.”

Mr. Dahl further states that the level of impairment between a BAC of .06 and .09 is significant. According to a study of impaired driving crashes, a driver with a BAC of .06 is about 1.6 times more likely to cause a crash than a sober driver. For a driver with a BAC of .09, that jumps up to 3.5 times more likely. “Don’t judge your own impairment based on how someone else handles the same amount of alcohol, and always have a plan for a safe ride home before going out for drinks,” says Dahl.

Regardless of your gender, please contact my office if you, a friend or relative faces charges of DUI. These charges are serious, threaten careers and can significantly limit one’s driving privileges.

State Senate Passes Bill Making Fourth DUI a Felony.

Image result for dui and politics

The WA State Senate has unanimously passed a bill that would make driving under the influence (DUI) a felony if the driver has three or more prior offenses on their criminal record within 10 years.

Senate Bill 5037 passed Thursday and now heads to the House, where it has stalled in previous years. The bill’s sponsors are as follows: Padden, Frockt, O’Ban, Darneille, Miloscia, Kuderer, Zeiger, Carlyle, Pearson, Conway, Rolfes, Palumbo, Angel, and Wellman.

Under the measure, a person who is charged with a fourth DUI, and has no other criminal history, would be subject to a standard sentencing range of 13 to 17 months in jail.

However, this bill allows first-time felony offenders to spend up to six months in jail, instead of nine, and finish out the rest of their sentence under supervision, such as attending Alcoholics Anonymous meetings and other programs.

My opinion? We shouldn’t be surprised. Over the past 20 years, Americans have seen a significant increase in the harsh penalties for intoxicated drivers. Perhaps this is necessary move given the thousands of lives lost to drunk drivers. Speaking as a criminal defense attorney, there’s serious question as to whether people commit these violations purely out of willful disregard for the law and for the safety of others or because of an untreated mental illness or alcohol addiction. Nevertheless, public outcry has led to increased sentences.

Many attorneys in Whatcom County and Skagit County claim to represent clients in DUI cases, but not all attorneys have the experience and successes of attorney Alexander F.

New Federal Data Shows Decrease in Drunk Driving Rates

Image result for decrease in dui

According to reporter Christopher Ingraham of the Washington Post, new federal statistics show that the rate of drunken driving in the United States fell to a 13-year low in 2014, the latest year for which data is available. The rate of driving under the influence of illicit drugs has not changed meaningfully in recent years but remains slightly lower than it was in 2008 and 2009 at the start of the Obama administration.

Here’s a summary of some other findings:

  • In 2014, 27.7 million people aged 16 or older (11.1 percent) drove under the influence of alcohol in the past year, and 10.1 million (4.1 percent) drove under the influence of illicit drugs in the past year. About 7.0 million (2.8 percent) drove under the influence of alcohol and illicit drugs in the past year, including 5.9 million (2.4 percent) who drove under the simultaneous influence of alcohol and illicit drugs in the past year.
  • The percentage of people driving under the influence generally increased with age through the young adult years and then declined with age thereafter; percentages were higher among males than females.
  • The percentage of people aged 16 or older who drove under the influence of alcohol in 2014 (11.1 percent) was lower than the percentages in 2002 through 2012 (ranging from 11.8 to 15.3 percent).
  • The percentage of people aged 16 or older who drove under the influence of illicit drugs was lower in 2014 (4.1 percent) than in 2002 through 2006 and in 2009 through 2010.
  • The percentage of people aged 16 or older who drove under the simultaneous influence of alcohol and illicit drugs was lower in 2014 (2.4 percent) than in 2002 through 2010 (ranging from 2.9 to 3.4 percent).

Ingraham reported that although experts caution that while the trend is heading in the right direction, there’s still a lot of work to be done. “Although it is heartening to see a downward trend in levels of driving under the influence of alcohol, it still kills thousands of people each year and shatters the lives of friends and loved ones left behind,” said Frances Harding, director of the Center for Substance Abuse Prevention at SAMHSA, the agency that produces the survey.

The SAMHSA survey showed that young adults — particularly men ages 21 to 25 — had by far the highest impaired driving rates. More than 1 in 5 men ages 21 to 25 drove drunk in 2014, nearly 1 in 7 drove under the influence of other drugs, and roughly 1 in 12 drove while simultaneously drunk and drugged.

One the other hand, young adults have also seen the greatest reductions in drunken driving prevalence over the past 13 years. Since 2002, the drunken driving rate fell by fewer than three percentage points among drivers age 26 and older. But the rate among drivers ages 21 to 25 dropped by more than 10 percentage points. And the prevalence among the youngest drivers, ages 16 to 20, fell by more than half.

Ingraham reports there’s no single factor driving the decline in drunken driving rates. The Centers for Disease Control and Prevention credits interventions like strong drunken driving laws, public awareness campaigns, and ignition interlock systems that don’t allow drunk drivers to start cars.

Some states are experimenting with innovative programs that essentially take away the right to drink alcohol, period, for people convicted of certain alcohol-related crimes. There’s also evidence that ride-sharing services like Uber can reduce drunken driving rates, although not all researchers agree on this.

My opinion? This is extremely good news. Although it’s important to save lives by reducing traffic accidents through education, prevention, and all other possible measures; it’s equally important that defendants facing these criminal charges hire capable and competent defense counsel as soon as possible to protect their rights, review the evidence and ensure a fair trial when necessary.

What Happened After Voters Legalized Recreational Marijuana?

Reporter Christopher Ingraham of the Washington Post wrote an article discussing how that the availability of recreational marijuana — in Colorado and elsewhere — is having little to no effect on teens’ propensity to smoke weed.

COLORADO

In his article, Ingraham supports his claim with the official statistics out of Colorado through 2015. It’s also what federal data shows nationwide through this year. And it’s also backed up by other federal surveys of drug use in the states where marijuana is legal.

It appears the data on this point has been consistent enough that longtime skeptics of the merits of marijuana legalization, like Nora Volkow of the National Institute on Drug Abuse, are expressing surprise at the findings. “We had predicted based on the changes in legalization, culture in the U.S. as well as decreasing perceptions among teenagers that marijuana was harmful that [accessibility and use] would go up,” Volkow told U.S. News and World Report earlier this month. “But it hasn’t gone up.”

WASHINGTON

However, a study out Tuesday in the journal JAMA Pediatrics flies somewhat in the face of the new conventional marijuana wisdom. Examining marijuana use among high school students in Washington state two years before and after the vote to legalize in 2012, it finds that rates of marijuana use increased by about 3 percent among 8th- and 10th-graders over that period.

INTERPRETING THE FINDINGS

The authors posit that reduced stigma about marijuana use is one factor leading to the results that they observed.

“Our study suggests that legalization of marijuana in Washington reduced stigma and perceived risk of use,” said lead author Magdalena Cerdá of the University of California in Davis in a news release, “which could explain why younger adolescents are using more marijuana after legalization.”

The findings are something of a puzzle. The study found no change in marijuana use among 12th-graders in Washington state, which the authors said could be because the 12th-graders in the study were old enough that “they had already formed attitudes and beliefs related to marijuana use” before the legal change.

The study also found no change in use among students at any grade level in Colorado. The authors write that Colorado had a robust medical marijuana industry in place well before full legalization, which may have affected youth attitudes and behaviors there before the study period.

Among adolescents, the perceived harmfulness of marijuana has been declining for decades among all age groups. But at the same time, adolescent use of marijuana has been flat or falling. This has led some researchers, including Mark Kleiman of New York University, to rethink the nature of the link between what teens think about weed and whether they use it.

In an email, Kleiman pointed out that in Washington state, the recreational marijuana market didn’t open until halfway through 2014, and then only in limited form. That’s halfway through the “after” period (2013 to 2015) in the JAMA Pediatrics study.

“The effect of the legalization initiatives themselves on price and availability of cannabis really wasn’t felt until after” the study’s surveys were done, Kleiman said. “Any measured effect would be more likely the result of the political campaign around legalization than legalization itself.”

Indeed, the study’s authors agree with that assessment. “Simply legalizing an activity can change people’s views about it and can change their behaviors as well,” said co-author Deborah Hasin of Columbia University in an email.

 

Refusing Field Sobriety Test is Admissible as “Consciousness of Guilt.”

In State v. Mecham, the WA Supreme Court decided that Prosecutors in DUI trials may admit evidence that a defendant is declining field sobriety tests as evidence of consciousness of guilt.

FACTS

In 2011, Officer Campbell made a traffic stop of defendant Mark Tracy Mecham. Although Mecham’s driving showed no signs of intoxication, Mecham smelled of intoxicants and had slurred speech. The officer asked Mecham to perform voluntary field sobriety tests (FSTs), which would have involved Officer Campbell’s observing Mecham’s eye movements and ability to walk a straight line and stand on one leg. Mecham refused.

At trial, Mecham moved to suppress his refusal to perform the FSTs. Typically, trial courts grant this defense motion. In Mecham’s case, however, the trial court denied his motion and ruled that even if FSTs were a search, probable cause supported the search. Mecham’s refusal was admitted to the jury as evidence to support the Prosecutor’s theory that Mecham exhibited “Consciousness of Guilt.” The jury found Mecham guilty of DUI.

Eventually, Mecham’s case was appealed to the WA Supreme Court. He argued that his right to be free from unreasonable searches was violated when the trial court admitted evidence of his refusal to undergo FSTs.

THE DECISION

Unfortunately for Mecham, the WA Supreme Court disagreed and upheld his DUI conviction. In a deeply divided decision, the Court held that while a FST is a seizure, it is not a search either under article I, section 7 of the Washington Constitution or under the Fourth Amendment to the United States Constitution. The State may, therefore, offer evidence of a defendant’s refusal to perform FSTs. Field sobriety tests may only be administered when the initial traffic stop was supported by reasonable suspicion and the officer has reasonable suspicion that the defendant was driving under the influence.

The lead majority opinion was authored by Justice Wiggins. Justice Fairhurst concurred in part and dissented in part. Justice Fairhurst would prohibit the administration of FSTs once the defendant is already under formal arrest for an offense other then DUI. Justice Johnson dissented on the grounds that the defendant had been told by the officer who administered the FSTs that they were voluntary. Finally, Justice Gordon McCloud dissented on the grounds that FSTs are searches.

My opinion?

I agree with Justice McCloud’s dissent. Here’s a portion:

“An FST can reveal information about a person’s body and medical history that are unquestionably private in nature. According to the National Highway Traffic Safety Administration (NHTSA), in addition to possible inebriation, FSTs can reveal a head injury, neurological disorder, brain tumors or damage, and some inner ear diseases. These conditions are not necessarily observable in the subject’s normal public behavior; they may well be revealed only by the special maneuvers the subject is directed to perform during the FST. Indeed, if an FST did not reveal information beyond what is readily observable by the general public, there would be no need to administer it in the first place. I therefore conclude that FSTs are searches under article I, section 7 of our state constitution.”

FSTs are a search. Period. Clearly, Officers who ask citizens to performs FSTs are seeking evidence of DUI. Because FSTs are a search, Mecham had a constitutional right to refuse to perform them unless (1) the officers had a warrant, or (2) an exception to the warrant requirement applied. Here, the Officer neither possessed or obtained a warrant for a blood test. Nor did the Officer even attempt to get a warrant.

Even more concerning, Prosecutors now have free reign to spin a citizen’s refusal of FSTs as “consciousness of guilt.” That’s unfair. Indeed, there’s a lot of debate in criminal law on whether FSTs accurately and/or scientifically indicate whether someone is DUI. These tests are, quite simply, balancing and memory tests administered under extremely uncomfortable and stressful conditions. These tests – which more of less reflect bad balance, lack of memory and preexisting health issues – simply do not accurately depict intoxication.

AAA Questions Marijuana DUI Laws

According to a news article from the Chicago Tribune, recent studies conducted by car insurer AAA find that blood tests given to drivers suspected of marijuana DUI have no scientific basis.

A handful of studies released by the AAA Foundation for Traffic Safety found that drivers can have a low level of THC, the active ingredient in marijuana, in their blood and be unsafe behind the wheel, while others with relatively high levels may not be a hazard. Below are the individual studies accompanied by capsule summaries comprising the effort:

“If you’ve had marijuana whether it’s medicinal or otherwise, don’t drive,” said AAA Chicago spokeswoman Beth Mosher, “It’s really that simple.”

The studies examined the results of more than 5,300 people nationwide who were arrested for driving under the influence of marijuana, 600 of whom tested positive for THC only, while the others had THC and other substances. This is because marijuana isn’t metabolized by the body in the same way as alcohol. The researchers compared the Drug Recognition Expert (DRE) exam results of 602 drivers that only had THC present in their blood at the time of arrest to those of 349 volunteers that took the test drug-free and sober. Ultimately, the degree to which a driver is impaired by marijuana use depends a lot on the individual, the foundation said.

The data appears confusing because AAA also looked at Washington – one of the first states to legalize marijuana – and found fatal crashes involving drivers who recently used marijuana doubled.

“ In most recent data 1 in 6 drivers who are involved in a fatal crash there had marijuana in there system,” Mosher  said.  “And as more and more states look at legalizing marijuana we see this as a concerning trend.”

Nevertheless, AAA is sending the message that the legal limits established for marijuana are arbitrary. A handful of states have moved to specify the maximum amount of active THC — the main chemical in marijuana — that drivers can have in their system. But AAA says that doesn’t work.

“We think those are meaningless,” said Mosher. “They are not backed by any science. One person can have one limit of THC in their blood and be significantly impaired and others can have that same limit and not be impaired at all,” Mosher said.

Many in law enforcement and AAA say that officer recognition of impaired drivers is really the only what to determine whether someone is too high to drive.  Of course all of this a public safety concerns as pot becomes legal across the country.

The Neurology of Risky Driving Behavior

A very interesting article from the Association for Psychological Science discusses how a team of Canadian psychological scientists is looking at the personality, cognitive, and neurobiological factors that contribute to reckless driving behavior. By better understanding the patterns of emotional processing and risk perception shown by repeat offenders, the researchers hope to design interventions that more effectively target these subgroups of dangerous drivers.

The evidence certainly exists. According to the article, drunk driving accounts for 35-40% of all driver fatalities in Canada and the United States, and drunk driving crashes kill more than 10,000 Americans every year. Amazingly, an estimated 30% of DUI offenders will continue to drink and drive, even after being arrested and punished.

“Surprisingly, these drivers usually don’t consider themselves as risk takers,” lead author Thomas G. Brown of McGill University said. “If drivers don’t believe they are risky, they will not accept the need to change. On the other hand, if we and they don’t understand their behavior, how can they be expected to change it effectively?”

The study began when Brown and his colleagues recruited four groups of male drivers who had different criminal histories: 36 men with at least two convictions for drunk driving (DUI group); 28 reckless drivers with at least three speeding violations in the past two years (speeders); 27 men with arrests for both DUI and speeding (DWI-speeders); and 47 low-risk drivers with no history of serious traffic offenses (control group).

According to the article, participants completed a battery of personality and impulsivity assessments, ranging from a Big Five personality measure to an executive control task that assessed their sensitivity to punishment and reward. Participants’ cortisol response, a hormonal reaction to stress, was measured by collecting saliva samples before and after they completed a timed mental arithmetic task previously shown to elicit stress.

Even more interesting, participants also completed a session of simulated driving that included driving on virtual highways, merging lanes, turning at intersections, and avoiding pedestrians.

The researchers found that different subgroups of risky drivers had distinctive neurobiological profiles. Compared to the low-risk control group, speeders were prone to making decisions based on thrill-seeking and a need for high levels of stimulation. Repeat DUI offenders, in contrast, had the lowest level of risk-taking behavior while sober.

“One possibility in line with the present results is that once heavy drinking has occurred, more impulsive drivers are more vulnerable to alcohol’s disruptive effects on the behavioral control mechanisms required to avoid DWI,” the researchers explain.

All of the dangerous driving groups exhibited significant blunting in their cortisol stress response compared with the control group. Cortisol, along with other stress hormones, influences cognitive processes that range from risk assessment to encoding emotional memories. These results suggest that dysregulation of the body’s cortisol response could act as a neurobiological marker for risky driving behavior.

“Relative to the other [risky driving] profiles considered here, the profile exhibited by group DUI may be the most amenable to interventions that aim to augment recall of the negative consequences of DUI behavior and pre-emptively decouple alcohol use from driving,” the researchers conclude.

Stated differently, interventions designed to improve drivers’ recall of the negative consequences of drinking and driving are effective for preventing drunk driving. This explains the findings why repeat DUI offenders had the lowest level of risk-taking behavior while sober.

My opinion? The study is interesting, for sure. Not surprisingly, the criminal justice system uses many of these these psychological deterrents to “decouple alcohol use from driving.” When it comes to DUI cases, gaining a worthwhile reduction of the charges often means the defendant obtaining an alcohol/drug evaluation, attending mandatory treatment, attending AA meetings and attending a Victim Impact Panel. Additionally, the financial costs of DUI fines and mandatory ignition interlock devices are constant reminders to DUI offenders that future risky behavior is simply not worth it.

That said, hiring a competent DUI attorney to fight DUI charges might be a worthy endeavor. The basic legal issues surrounding a DUI arrest are (1) whether the stop was lawful, (2) whether there was enough evidence to arrest, (3) whether the officer informed the defendant of Implied Consent Warnings, and (4) whether the defendant either (a) refused the BAC breathalyzer machine or (b) blew over .08 and/or had .05 nanograms of active THC in their blood when pulled over.

If you’re charged with DUI, the best advice is to immediately contact a competent DUI defense attorney to discuss your case. Good luck!

State v. Pearson: DUI Blood Draw Held Unlawful

In State v. Pearson the WA Court of Appeals Division I held that (1) exigent circumstances did not support a warrantless blood draw for marijuana, (2) it’s reversible error to discuss the .05 THC limit in a DUI case that arose prior to the passage of I-502.

Defendant Tamisha Pearson was a medicinal marijuana patient due to numerous health problems. She struck a pedestrian with her car, pulled over and called 911. Seattle Police Officers arrived. Officer Jongma was a drug recognition expert. Pearson initially denied consuming any drugs or alcohol that day. She agreed to perform field sobriety tests.

Some of Pearson’s behavior during the sobriety tests indicated she was impaired. Pearson told Officer Jongma that she is authorized to consume medicinal marijuana and that she had smoked earlier in the day. Based on that, Officer Jongma arrested Pearson for suspicion of Vehicular Assault and DUI.

Officer Jongma transported Pearson to Harborview Medical Center for a blood draw. They arrived at the hospital at approximately 5:26 pm—2 hours after the initial collision and 1 hour and 20 minutes after Officer Jongma arrived on the scene. At approximately 5:50 pm, a nurse drew Pearson’s blood without her consent and without a warrant. A toxicologist analyzed Pearson’s blood sample for cannabinoids on February 21, 2012. The analysis determined Pearson’s THC concentration was approximately 20 nanograms.

On August 18, 2012, the City of Seattle charged Pearson in Seattle Municipal Court on one count of driving while under the influence of an intoxicating drug. The court initially granted Pearson’s motion to suppress the blood evidence.

TRIAL

At trial, the City introduced testimony of forensic toxicologist Justin Knoy of the Washington State Toxicology Laboratory. Over Pearson’s objection, the City elicited testimony from Knoy that the per se legal limit of THC concentration under Washington law was 5 nanograms. At the time, however, no per se limit for THC concentration in Washington existed when the accident occurred. The jury found Pearson guilty of DUI.

ISSUES ON APPEAL

The Court of Appeals addressed four issues: (1) whether exigent circumstances existed to justify the warrantless extraction of Pearson’s blood, (2) whether exigent circumstances existed to justify the warrantless testing of Pearson’s blood, (3) whether the trial court erred when it failed to include Pearson’s proposed jury instruction, and (4) whether the trial court erred when it permitted Knoy to testify that the per se legal limit for THC concentration was 5 nanograms.

1.Exigent Circumstances did NOT Exist to Justify Extracting & Testing Pearson’s Blood.

First, the Court of Appeals decided the City failed to show that obtaining a warrant would have significantly delayed collecting a blood sample. It reasoned that the natural dissipation of THC in Pearson’s bloodstream alone did not constitute an exigency sufficient to bypass the warrant requirement.

2. Trial Court Mistakenly Admitted Testimony From Toxicologist.

Second, the Court of Appeals decided the trial mistakenly admitted testimony from the toxicologist regarding THC limits. At the time, evidence of the .05 legal THC limit was NOT in effect when the offense occurred and was irrelevant to the central question at trial—whether Pearson’s ability to drive was lessened in any appreciable degree by her use of marijuana. The court reasoned the evidence was highly prejudicial because the blood test showed that Pearson had a THC concentration of 20 nanograms. Consequently, evidence of the current per se legal THC limit of 5 nanograms invited the jury to retroactively apply law that was not in effect at the time of the alleged offense and conclude that the blood evidence alone was sufficient to prove guilt.

3. The Defendant’s Jury Instruction Was Properly Denied. 

At trial, the lower court denied the Defendant’s proposed jury instruction:

It is not unlawful for a person to consume a drug and drive. The law recognizes that a person may have consumed a drug and yet not be under the influence of it. It is not enough to prove merely that a driver had consumed a drug.

The Court of Appeals held that, under these circumstances, the trial court did not abuse its discretion when it refused to include Pearson’s proposed jury instruction because she was able to argue her theory of the case based on the instructions given.

In conclusion, the Court of Appeals reversed the Defendant’s conviction and remanded it back to the lower court.

My opinion? Good rulings; especially the one regarding the mistakenly-admitted testimony from the Toxicologist. I-502’s legal limits regarding THC was not in effect at that time. Having a witness testify to limits was, therefore, a mistake.

Proposed Law Would Require Bartenders to Cut Drunk People Off

A news article written by S.E. Smith of www.care2.com reveals that a new bill was introduced into the California State Assembly that would require bartending personnel and managers to undergo training in how to handle alcohol and cut off intoxicated customers.

Under the Responsible Interventions for Beverage Servers Training Act of 2016 (RIBS), Assembly Bill 2121 would require bartenders to intervene when a bar customer has had too much to drink. The law, which if passed would go into effect in 2020, hopes to save lives decrease DUI, and curb drunk drivers. Bartenders would be required to complete a minimum of four training hours on subjects like recognizing intoxication and understanding the physical and social effects of alcohol. The course would also examine state laws surrounding beverage service. Every three years, participants would need to renew their certifications.

Although the California Business & Professions Code reveals that bartenders have always practiced some discretion in this area, the bill would create a more robust legal framework and provide bars with specific training requirements for staff. Furthermore, the legislation would ensure that bartenders across the state follow the same curriculum when they learn how to interact with customers.

According to S.E. Smith, one of the most frustrating parts of the job can involve making judgement calls about when someone has had too much to drink and needs to go home. Some states – including Washington State – have “cut off” laws requiring bartenders to stop serving intoxicated customers. Most have laws barring service to people who are already drunk. Individual bars also have their own policies and procedures for handling customers.

Drunk drivers are the main concern here. Intoxicated people who hurt themselves — an uninsured person who requires care for a broken limb, for instance —  may create public health nuisances and expenses. However, when intoxicated people get in cars, the decision can be fatal.

S.E. Smith emphasizes that 30 people die as a result of drunk driving every day in the United States, including sober drivers in other vehicles, pedestrians and cyclists. One third of traffic deaths can be attributed to intoxicated driving.

My opinion? Similar to Ms. Smith, this bill is a step in the right direction. Many of my DUI clients tell me they were over-served at the bars they frequented before being pulled over for DUI. It helps to have backup — like policies a bartender can apply — to remind a customer that they’re breaking the law if they kept serving.

Stoned Drivers Hit Test Course To Evaluate Marijuana DUI Limits

An article from the Denver Huffington Post addressed an interesting question regarding the regulation of legal marijuana: how high is too high to drive?

Given the lack of precedent, Washington TV station KIRO opted to observe actions over words. The station assembled a group of volunteers, had them smoke pot (appropriately, the strain was called “blueberry train wreck”), and set them loose on a driving test course.

Here’s the video.

A handful of police officers stood nearby, watching any telltale signs of stoned driving. Also, a driving school instructor sat in the passenger’s seat, ready to take the wheel or stomp the brake pedal at a moment’s notice.

Unfortunately, the results (while entertaining) don’t add much clarity to the question at all. A regular smoker of marijuana tested above the legal limit to begin with, yet drove without much of a problem (at least initially). Two casual smokers also navigated the course without incident. (Spoiler alert: after smoking more marijuana, things devolve quickly).

In 2012, Colorado legislators declined to pass a law that would have limited drivers to 5 nanograms of THC, the psychoactive ingredient in marijuana, per milliliter of blood.

“This is a bit of unprecedented territory, so trying to find the right approach has proven difficult and cumbersome,” explained Rep. Dan Pabon, a lawmaker on Colorado’s marijuana-legalizing task force, to CBS News in 2012.

Washington lawmakers, meanwhile, passed a law in 2012 setting the threshold for legal impairment at 5 nanograms of THC, reports NPR.

Ultimately, though, it comes down to common sense. Explains Bob Calkins, a Washington State Patrol spokesman, to The Oregonian, “We don’t just pull people over and draw blood… If you’re driving OK, we’re not going pull you over. But driving impaired is still driving impaired.”
