Evaluation of Field Sobriety Tests for Identifying Drivers Under the Influence of Cannabis

Evaluation of Field Sobriety Tests for Identifying Drivers Under the Influence of Cannabis

This randomized clinical trial investigates the accuracy of field sobriety tests administered by law enforcement officers to assess functional impairment and driving performance among individuals who have smoked cannabis.

Question

How accurate are field sobriety tests (FSTs) in identifying acute Δ9-tetrahydrocannabinol (THC) impairment?

Findings

In this randomized clinical trial of 184 cannabis users randomized to THC or placebo, law enforcement officers classified 81.0% and 49.2%, respectively, as FST impaired, and officers suspected that 99.2% of FST-impaired participants received THC. Driving simulator performance was associated with select FSTs.

Meaning

In this study, FSTs differentiated between THC- and placebo-exposed participants; however, the substantial overlap of FST impairment between groups and the high frequency at which FST impairment was suspected to be due to THC suggest that absent other indicators, FSTs alone may be insufficient to identify THC-specific driving impairment.

Meanwhile… until they figure it out, if you get a DUI for being under the influence of cannabis, although legal, you will need an experienced attorney to fight for you in the court system. If you want to fight call our office. If you don’t, well then settle for what they dish out and accept that you can’t go back and change the outcome.

THC Detection in Blood: A Comprehensive Review

Tetrahydrocannabinol (THC), the main psychoactive compound in marijuana, can remain detectable in the blood for several days or even weeks after use. This is due to the fact that THC is highly fat-soluble, meaning that it dissolves easily in fat cells. Once THC is absorbed into the bloodstream, it is distributed throughout the body, including the fat cells. When THC reaches the brain, it binds to cannabinoid receptors, producing the intoxicating effects associated with marijuana use.

As the intoxicating effects of THC wear off, it is released from the brain and redistributed to other tissues, including the fat cells. THC can be stored in fat cells for weeks or even months, and it is released slowly back into the bloodstream over time. This means that a blood test for THC can detect past marijuana use, even if the individual is no longer under the influence.

Factors that Affect THC Detection in Blood

A number of factors can affect how long THC remains detectable in the blood, including:

  • Frequency of use: Chronic marijuana users tend to have higher THC blood levels than occasional users.
  • Metabolism: Individuals with faster metabolisms tend to clear THC from their system more quickly.
  • Body composition: Individuals with higher body fat percentages tend to have higher THC blood levels.
  • Method of use: Different methods of marijuana use can result in different THC blood levels. For example, smoking marijuana tends to result in higher THC blood levels than eating marijuana.

Interpretation of THC Blood Test Results

It is important to note that THC blood levels do not necessarily correlate with impairment. Some individuals with high THC blood levels may not be impaired, while others with low THC blood levels may be impaired. Other factors, such as individual tolerance, route of administration, and time since use, can also play a role.

Additional Scientific Details

In addition to the information above, here are some additional scientific details about THC detection in blood:

  • THC is metabolized by the liver into a number of different metabolites, including 11-hydroxy-THC (11-OH-THC). 11-OH-THC is more potent than THC and has a longer half-life, meaning that it remains in the body longer.
  • The half-life of THC in the blood ranges from 1.3 to 13 days, depending on the individual’s metabolism and other factors.
  • THC can be detected in blood using a variety of analytical methods, including gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-mass spectrometry (LC-MS).

Future Research Directions

Additional research is needed to better understand the relationship between THC blood levels and impairment. Researchers are also working to develop new methods for detecting THC in blood that are more sensitive and specific.

Can I have open alcohol in a trailer that is being pulled on the road?

Can I have open alcohol in a trailer that is being pulled on the road?

Question: Can I have open alcohol in a trailer or camper that is being pulled on the road?

Answer:  In most instances transporting or possession of open intoxicants in a vehicle is not permitted.  

MCL 257.624a states in part, “a person who is an operator or occupant shall not transport or possess alcoholic liquor in a container that is open or uncapped or upon which the seal is broken within the passenger compartment of a vehicle upon a highway, or within the passenger compartment of a moving vehicle in any place open to the general public or generally accessible to motor vehicles, including an area designated for the parking of vehicles…”

There are limited exceptions in cases where the transportation of an open or uncapped alcoholic liquor in the passenger compartment of a vehicle are permitted.

They include times when the vehicle does not have a trunk or separate area from the passenger compartment, and the container is in a locked glove compartment, behind the last upright seat, or in an area not normally occupied by the operator. There are additional exceptions in the case of a chartered vehicle such as a limousine or chartered bus.

Michigan’s DUI Laws and Penalties

Michigan’s DUI Laws and Penalties

Michigan’s OWI Laws and Penalties

An DUI / OUI / OWVI conviction requires proof only that the driver shows visible signs of impairment due to ingesting alcohol or drugs.

The Michigan Law

Under MCL 257.625(3), you are assumed guilty of a crime if, regardless of your blood alcohol content, your ability to operate a vehicle was “visibly impaired” by alcohol.

This is referred to as “operating while visibly impaired” or OWVI.

Michigan’s OWI and OWVI Laws

There are two main categories: operating while under the influence of drugs or alcohol (OWI) and operating while visibly impaired (OWVI) by drugs or alcohol. Some people still use the term DUI, but it’s the same thing as OWI.

An OWI is the more serious offense. It means you were driving while:

  • under the influence of alcohol or drugs
  • had a blood alcohol content (BAC) of .08% or greater
  • had any amount of illegal drugs in your body

Once again –> an OWVI conviction only requires proof that you only showed visible signs of impairment due to alcohol or drugs.

 

This is why you need to retain a lawyer.  Even if your going to take a plea.

 

Michigan’s OWI and OWVI Penalties

If you’re convicted of OWI or OWVI, you’ll face penalties according to Michigan law. For most convictions, you’ll lose your license, pay fines, and possibly go to jail.

How Long an OWI or OWVI Stays on Your Record in Michigan

OWIs and OWVIs stay on your record for seven years in Michigan. This means that if you get another conviction within seven years, it will count as a prior conviction and you’ll face harsher penalties.

 

Michigan DUI Penalties

1st Offense

If you are caught driving under the influence (DUI) in Michigan for the first time, you may face up to 93 days in jail (up to 180 days if your blood alcohol content (BAC) was .17% or greater). You may also be fined $100 to $500 ($200 to $700 if your BAC was .17% or greater) and ordered to complete up to 360 hours of community service.

2nd Offense

If you are caught DUI for the second time, you may face 5 days to one year in jail, a fine of $200 to $1,000, and 30 to 90 days of community service. Your vehicle may also be immobilized for 90 to 180 days (if not forfeited).

3rd Offense

If you are caught DUI for the third time, you may face one to five years in jail (30 days to one year if community service is ordered), a fine of $500 to $5,000, and 60 to 180 days of community service. Your vehicle may also be immobilized for one to three years (if not forfeited).

Jail

If you are caught DUI in Michigan, you may face jail time depending on the offense. The length of jail time increases with each subsequent offense.

 

Vehicle Immobilization for OWI and OWVI Convictions in Michigan

If you are convicted of operating while intoxicated (OWI) or operating while visibly impaired (OWVI) in Michigan, the judge may order the immobilization or forfeiture of your vehicle. For a first offense, immobilization or forfeiture is optional, but for any subsequent offense, it is mandatory. The length of immobilization increases with each subsequent offense.

  • 1st offense. Possibly forfeiture or immobilization for up to 180 days.
  • 2nd offense. Immobilization for 90 to 180 days is mandatory (if not forfeited).
  • 3rd offense. Immobilization for one to three years is mandatory (if not forfeited).

 

Michigan’s OWI Enhancements for Passengers Under 16 Years Old

If you are caught DUI with a passenger under 16 years old in Michigan, you may face additional penalties. For a first offense, you may be fined $200 to $1,000 and either serve five days to one year in jail or complete 30 to 90 days of community service. For a subsequent offense with a passenger under 16, you may be fined $500 to $5,000 and either serve one to five years in jail or probation (which must include five days to one year in jail and 30 to 90 days of community service).
