Describing Alcohol Odor Evidence In Court: Effective Strategies

When it comes to legal proceedings, the odor of alcohol is a phrase used by police officers to justify DUI investigations. However, the smell of alcohol alone is insufficient evidence to prove legal intoxication or impairment. While it may indicate recent alcohol consumption, it does not provide information about the quantity consumed or the time of consumption. The aroma associated with alcoholic beverages is primarily due to congeners, the ingredients used in brewing and production, and not the alcohol itself, which is largely odourless. In court, an officer's description of the odor of alcohol may be challenged, as it is subjective and can be influenced by factors such as proximity and individual sensitivity. The officer may also be questioned about the specific type of alcoholic beverage detected and the number of drinks consumed, which are typically unknown based solely on the odor.

The limitations of describing the smell of alcohol in court

While the smell of alcohol on a person's breath may be used as evidence that they have been drinking, it is not sufficient evidence to prove that they are under the influence of an intoxicant. This is because alcoholic beverages with a lower alcohol content tend to have a stronger odour, and the odour of alcohol itself is typically imperceptible. Thus, the odour of alcohol on a person's breath may be due to a single drink with a low alcohol content rather than multiple drinks with a high alcohol content. Furthermore, the odour of alcohol may be due to spilled drinks or proximity to other drinkers in a crowded bar.

In DUI cases, the odour of alcohol on a driver's breath is insufficient to establish probable cause for a DUI arrest. For example, Florida Statute Section 901.15(5) states that "probable cause for a DUI arrest must be based upon more than a belief that a driver has consumed alcohol; it must arise from facts and circumstances that show a probability that a driver is impaired by alcohol or has an unlawful amount of alcohol in his system". Similarly, in Moye (1970), the court held that an "odor of alcohol on the breath of the driver of an automobile is evidence that he has been drinking [but] an odor, standing alone, is no evidence that he is under the influence of an intoxicant".

However, the odour of alcohol on a person's breath can be used as evidence to support other indicators of impairment. For example, in State v. Dark (1974), the court held that an officer had probable cause to arrest the defendant for impaired driving after seeing him drive, lawfully stopping him, smelling alcohol, and "observing his condition". Similarly, in State v. Rogers (1996), the court of appeals affirmed the trial court's determination that the officer had probable cause to believe the defendant was driving while impaired based on the odour of alcohol and a single ALCO-SENSOR reading of .13.

Nevertheless, there are limitations to relying on the odour of alcohol as evidence in court. Firstly, it is difficult to quantify the amount of alcohol consumed based solely on the odour. While an officer may be able to tell that the defendant had been drinking a lot, they cannot determine the specific number of drinks consumed or the period of consumption. Secondly, it is challenging to identify the type of alcoholic beverage consumed based on the odour alone. More experienced officers may describe detecting the odour of an "alcoholic beverage" rather than the "odour of alcohol", as the former provides more specificity.

In conclusion, while the smell of alcohol may be used as a factor in determining impairment, it is not sufficient on its own to prove that a person is under the influence of alcohol. Additional evidence, such as bad driving, physical indicators of impairment, or breath alcohol screening test results, is necessary to establish probable cause or prove impairment in court.

The impact of the strength of the alcohol smell

In legal contexts, the strength of the alcohol smell can be described using terms such as "strong," "moderate," or "slight." For example, an officer may testify that the defendant exhibited a "strong smell of alcohol" during an arrest. This description of the odour's intensity can be subjective and vary depending on factors such as proximity and individual sensitivity to smells.

The strength of the alcohol smell can have varying impacts. On one hand, a strong odour of alcohol may indicate recent consumption or the type of beverage consumed. It may suggest that an individual has been drinking, but it does not necessarily indicate legal intoxication or impairment. Alcoholic beverages with lower alcohol content tend to have stronger odours, so the strength of the smell may not directly correlate with the amount of alcohol consumed or its effects.

Additionally, the strength of the alcohol smell can influence the perception of intoxication. A stronger odour may lead to a presumption of higher alcohol consumption or a potential impairment. However, it is important to note that the odour itself does not determine the level of intoxication. Other factors, such as behavioural indicators, field sobriety tests, and blood alcohol concentration (BAC) measurements, are required to establish legal impairment.

The impact of the alcohol smell's strength can also be influenced by individual factors. For example, some people may be more sensitive to smells and perceive a stronger odour even if the alcohol consumption is minimal. Additionally, the type of alcoholic beverage can play a role, as certain drinks have more pervasive scents, such as beer or wheat beers, while others like vodka may be less noticeable.

In legal defences, the strength of the alcohol smell may be questioned or challenged. Attorneys may argue that the odour could be due to spilled drinks, proximity to alcoholic beverages, or other environmental factors. They may also emphasise that the odour does not provide conclusive evidence of the amount or type of alcohol consumed, the timing of consumption, or the resulting level of impairment.

How the type of alcohol affects the smell

It is important to note that alcohol itself is essentially odourless. The smell of an alcoholic beverage comes from the ingredients used in the brewing and production of the beverage, known as congeners. These congeners include fusel oils, which are a mixture of thick, evaporative liquids produced in small quantities during the fermentation process.

The type of alcohol consumed will affect its smell. Beer, for example, has a more pervasive scent than vodka due to its lower alcohol content. Beer gives off a distinct odour of yeast or malt, which can be difficult to pinpoint as alcohol abuse since it is commonly consumed socially. Wine tends to have a sweeter scent, often accompanied by a fruity aroma. Spirits and liquors may have a sharper scent, and bad breath is more common with liquor than with beer or wine. Clear spirits, such as vodka, do not give off much smell on their own but can contribute to a sweet and sour booze breath.

In the case of alcohol abuse, the smell of alcohol can be more pungent and likened to garlic. This is due to the build-up of alcohol in the body and the body's attempt to clear it, leading to lower saliva concentrations and an increase in bacteria in the mouth. Additionally, the process of alcoholic ketoacidosis can impact smell, resulting in a fruity odour similar to nail polish remover.

When describing the smell of alcohol in court, it is important to note that the odour of an alcoholic beverage is not a reliable indicator of intoxication. While an officer may detect the odour of an alcoholic beverage, they cannot determine the type of drink, the amount consumed, or the level of intoxication based solely on the smell. The odour of alcohol is only qualitative and cannot be used to quantify consumption or bodily alcohol levels.

The difference between the smell of alcohol on the breath and on the body

Alcohol breath, or "booze breath", comes from the lungs rather than the mouth, which makes it hard to get rid of the smell. Temporary fixes like cough drops, drinking coffee, and chewing gum may help mask the smell. However, the only surefire way to avoid alcohol breath is to not consume alcohol. The smell of alcohol on the breath is a clear sign of substance abuse, and it occurs when the body is trying to clear the alcohol out of the system. The length of time that bad breath lasts depends on the individual's overall alcohol consumption, how quickly their body metabolizes the alcohol, and how long ago they consumed their beverage.

On the other hand, alcohol abuse can also lead to body odour. Alcohol is treated as a toxin in the body, and it can change the way sweat smells, contributing to what is known as Alcoholic Ketoacidosis (AKA) smell. This is a serious condition that occurs when the body tries to get rid of excess ketones via exhalation from the lungs. AKA is more common in people who binge drink, and the smell tends to be more like nail polish remover. Additionally, a change in personal hygiene, such as an excess of cologne or scented lotions, may indicate an attempt to cover up the smell of alcohol through sweat and body odour.

In a legal context, the smell of alcohol on the breath or body is not sufficient evidence of impairment or intoxication. While an officer may testify that a defendant had a strong smell of alcohol, they cannot determine the type or amount of alcohol consumed based on the odour alone. Furthermore, the odour of alcohol could be the result of recent consumption, the type of beverage, or even a spill in a crowded bar. Therefore, the smell of alcohol should not be the sole basis for a DUI or OVI arrest, and additional evidence is typically required to support such charges.

Whether the smell of alcohol is enough to prove impairment

The smell of alcohol on a person's breath is considered key evidence in a DUI arrest. Police officers are trained to detect the smell of alcohol on a driver's breath during a traffic stop. However, the smell of alcohol alone may not be sufficient to establish probable cause for an arrest or a DUI charge. While the odor of alcohol can be a relevant factor in establishing probable cause for a DUI investigation, officers typically look for additional evidence, such as erratic driving behavior, slurred speech, and bloodshot eyes.

It is important to note that the strength of the alcoholic odor is typically unrelated to the driver's actual BAC (Blood Alcohol Content) levels. Ethanol, the type of alcohol that causes intoxication, has no scent. The aroma associated with alcoholic beverages comes from the congeners or ingredients used in their brewing and production. Alcoholic beverages with lower alcohol content tend to have a stronger odor, and it is challenging to determine the amount of alcohol consumed based solely on the odor.

In court, an officer may testify that they detected the odor of an alcoholic beverage but will likely be unable to identify the specific type of drink or the quantity consumed. An experienced officer will avoid claiming that they detected the "odor of alcohol" and instead refer to the "odor of an alcoholic beverage." Cross-examination of the officer may include questions about the distance from the defendant when the odor was detected and the possibility that the odor originated from spilled drinks or other environmental factors rather than direct consumption.

Additionally, the timing of alcohol consumption can be called into question. It takes time for alcohol to be absorbed into the bloodstream, and an argument can be made that drinks consumed shortly before an arrest may not have significantly affected the defendant's actions or driving ability at the time of the arrest. Therefore, while the smell of alcohol may indicate recent consumption, it does not provide sufficient evidence of impairment or intoxication.

In conclusion, while the odor of alcohol on a person's breath can be a factor in establishing probable cause for a DUI investigation, it is not enough to prove impairment on its own. Officers must rely on observable signs of impairment, performance on field sobriety tests, and other evidence to support a DUI charge.
