The Mathematics Of Blood Alcohol Concentration

Drinking and driving is said to be the primary contributor to automotive related deaths. “By law, a driver is considered to be impaired by alcohol if his or her blood alcohol content is 0.08 percent or higher” (Holzmueller). As a matter of fact, “in 2010, about 86 percent of all fatalities alcohol-involved crashes were in cases where a driver or pedestrian had a BAC of .08 or higher” (“The Economic and Societal Impact of Motor Vehicle Crashes, 2010” 147). Laws and penalties have been created and applied in recent years that make it more difficult to get away with drinking and driving. If drivers are charged with alcohol-impaired driving, “they face suspension or revocation of their license” (Holzmueller).

1.Explain the concepts of intoxication and blood alcohol concentration. Describe the common physical, emotional, and behavioral effects of alcohol consumption at low and high blood

Substance abuse is a key component to the problems that we face today as a society. According to the National Highway Traffic Safety Administration ("Alcohol-Impaired Driving", 2009) in 2009, 32% of all motor vehicle traffic fatalities in the United States were due to alcohol-impaired driving crashes. Surveys were also conducted by the National Highway Traffic Safety Administration (National Highway Traffic Safety Administration, Compton, & Berning, 2009) so researchers were able to estimate not only the prevalence of drinking and driving, but for the first time they were also able to collect data on the number of drivers who were under the influence of drugs that impaired their abilities. In this data, it was found that 16% of weekend night time drivers tested positive for impairing drugs, in contrast to the 2% of drivers who were at the legal alcohol limit; making drugs 7 times more prevalent. These statistics show that “drugged” driving is a concern for not only law enforcement but also puts other drivers at risk of becoming a part of future statistics.

The thought of alcohol being involved in fatal crashes brings about an emotional response. Recently, there has been a movement based on emotion rather than logic to change a certain drinking and driving law. This involves lowering the Blood Alcohol Content (BAC) from 0.10% to 0.08% nationwide. However, this attention is misdirected. By looking at my personal experiences, statistics, and current laws, it is clear that there is no need for lowering the BAC.

Driving under the influence has affected many people's lives and families. Today I would like to talk to you about the problems of drinking and driving, and why it is a concern for all of us. Driving under the influence is one of the most common and dangerous situations you can put yourself or someone else in. The fact is that drinking and driving is a huge deal and can leave a long trail of broken dreams and hearts. If you drink and drive, not only are you putting yourself at risk, but your passengers and the pedestrians outside of your vehicle. According to the most recent statistics by the National Commission Against Drunk Driving states that 17,000 Americans die each year in alcohol- related traffic crashes and 600,000 Americans

Drunk driving is an issue that effects many people across our nation. People do not realize the affects alcohol can have on the body and mind that slow decision making while driving. This issue begins in the home. Children see their parents, or other adults figures, have a beer or a cocktail and get in the car. Thus, making it seem like it is acceptable to drink and drive. “One in three people will be involved in an alcohol-related crash in their lifetime” (MADD).

Alcohol consumption can cause impairment while operating machinery or driving. Alcohol has be proven to affect two specifics part of the brain. The prefrontal cortex and the hippocampus. The prefrontal cortex is the center of attention while the hippocampus is the center of learning and memorization. While driving under the influence of alcohol, our attention (which is controlled by the prefrontal cortex) on the road is affected as well as our self-awareness. A second of inattention on the road can result in a deathly event. Thus, we can say that the specific deficit in driving behavior that makes alcohol consumption dangerous is the lack of

People seem to get the wrong impression that alcohol is classified as a stimulant or “upper”, but in actuality alcohol is a depressant. The short term physical effects depend on the blood-alcohol level. It ranges from random changes in mood to complete lack of coordination, impaired vision, lack of balance and slurred speech. However, larger amounts of blood alcohol can strongly effect brain functioning and eventually cause a person to “black out”. In examining the thought process for drinking and driving behavior, Kulick and Rosenberg (1999) found that while the majority of their college student sample frequently drove after drinking, these students rationalized this behavior in a variety of ways. The most commonly found reasons for driving under the influence of alcohol were the strong desire to get to a specific destination (e.g., home), convincing oneself as being only slightly intoxicated, and/or believing

People like to go to parties and have fun all the time and what’s a party without alcohol, right? The problem with drinking at parties, however, is that many don’t know that they have become drunk and end up driving around after they leave the party. Drunk driving is dangerous and those driving that have high blood alcohol content or concentration (BAC) increases their risk of causing or being a part of accidents such as vehicle crashes or highway injuries (“Driving,” n.d.). The article “About Drunk Driving” (n.d.) states that every 53 minutes on average, someone is killed in a drunken driving crash and every 90 seconds, someone is injured.

As to my own part, having turned my thoughts for many years, upon this important subject, and maturely weighed the several schemes of our projectors, I have always found them grossly mistaken in their computation. It is true. There are not enough drivers who drive under the influence. In the year 2001, MADD Online approximated that only one in ten drivers, a mere 25 million, drove drunk, and, consequently these drivers were the ones significantly more likely to be involved in a crash of some sort, but why shouldn’t we level the playing field? (1)

In 2010, 10,228 people were killed in alcohol-impaired driving crashes, accounting for nearly one-third (31%) of all traffic-related deaths in the United States. Of the 1,210 traffic deaths among children ages 0 to 14 years in 2010, 211 (17%) involved an alcohol-impaired driver. Of the 211 child passengers ages 14 and younger who died in alcohol-impaired driving crashes in 2010, over half (131) were riding in the vehicle with the alcohol-impaired driver. In 2010, over 1.4 million drivers were arrested for driving under the influence of alcohol or narcotics. That is one percent of the 112 million self-reported episodes of alcohol-impaired driving among U.S. adults each year.

In Jill Dombrauckas’s (2015) report, she discussed that the Pennsylvania DUI Association made a large amount of researches about alcohol’s effect on body systems. In one research, alcohol affects the central nervous system which means when the individual drink alcohol, the messages that are carried to and from the brain and the body’s muscles can be slowed delivery. For example, the incoming signals from the brain, like the painful sensory that will decrease the injury’s awareness. Also the signals from the brain to the muscles will lead the motor skills becoming insensitive.

“Alcohol related crashes kills someone in the U.S. every 22 minutes. At any minute, one of 50 drivers on the road is drunk and every weekend night, one out of 10 is drunk.(Kypri, 1994).” This quote means In United State, every 22 minutes there was a person killed by car accident involving alcohol. One of 50 drivers on the road was drunk at any minute; one of 10 is drunk in weekend night. The quote shows the number of traffic fatalities annually related to alcohol, do you realized what does those numbers truly represented? Those are the examples of drunk drive that got people killed in the life.

Alcohol is a very widely used drug, and is therefore present in many clinical and forensic toxicology cases. Quantitation of alcohol levels in patients affects the clinical treatment they receive as well as any legal consequences associated with the incident that led to their hospitalization. Alcohol analysis and its consequences for postmortem cases also forms a large part of the forensic toxicologist’s workload [1-2].
