A Night with Friends
Every 53 minutes, someone dies in a drunk driving accident. NHTSA- 2012

Whether it’s a night out with friends or a dinner party at your house;  be responsible and make sure that everyone has a fun and safe night. One of the best ways to help you achieve this is to know your Blood Alcohol Content (BAC). That is why an Alcovisor Satellite or Mars hand-held personal alcohol breath tester is a “must have” at any gathering where alcohol is being served. It is small, discreet and easy to use. And with the convenience of disposable mouthpieces, everyone at the party can take advantage of the peace of mind provided by knowing  their BAC.

Whether at home or out on the town, use PAS System’s personal breathalyzers to ensure that you have the easiest and most reliable way to measure your blood alcohol content and drink responsibly.


In 2010 there were almost 300,000 incidents of drinking and driving each day. CDC-2011

The teenage years are often some of the most exciting years of a person’s life; filled with many ups and downs, from Friday night football games and Senior Proms to big exams and heartbreaks.   It can often feel like a rollercoaster ride for both the youth AND their parents.  Unfortunately the highs, the lows and everything in between all have one thing in common; the increased risk of the use of alcohol by your teen.  

As a parent, you would do whatever it takes to keep your child safe. You are ever vigilant in keeping watch for problems or signs of trouble but teens have become equally adept at hiding them and avoidance.   Talking with your teen about alcohol is a must but sometimes that is not enough.  

Now you as a parent have a tool that will enable you to detect the use of alcohol in your teen; enabling intervention at the earliest level. 

Many teens are already familiar with alcohol testing devices as they have become common place at many schools. A growing number of schools are requiring students to submit to a breath alcohol test before being admitted to school functions such as dances and sporting events. 

Teens are particularly vulnerable to alcohol use. The physical changes of puberty might make your teen feel self-conscious and more likely to take risks – such as experiment with alcohol—to fit in or please others. Also, your teen might have trouble understanding that his or her actions can have adverse consequences. 

Common risk factors for underage drinking include:

  • Transitions such as the move from middle school to high school
  • Increased stress at home or school
  • Peer drinking and peer acceptance
  • Family problems, such as conflict or parental alcohol abuse
  • A history of behavior problems or mental health conditions

Consequences of underage drinking can include:

  • Alcohol- related fatalities.  Alcohol-related accidents are a leading cause of teen deaths. Teen drowning, suicides and murders also have been linked with alcohol use.
  • Sexual behavior.  Teens who drink tend to become sexually active earlier and have sex more often than do teens who don’t drink. Teens that drink are also more likely to have unprotected sex than are teens that don’t drink.
  • School problems.  Teens who drink tend to have more academic and conduct problems.
  • Alcoholism.  Those who drink at an early age are more likely to develop alcohol dependence later in life.
  • Increased likelihood to abuse other drugs. 
  • Changes in brain development that may have life-long effects.
  • Becoming a victim of a violent crime.  Alcohol use can inhibit your judgment and response time making you an easy target. Alcohol-related crimes might include rape, assault and robbery.

Warning Signs of underage drinking can include:

  • Academic and/or behavioral problems in school
  • Changing groups of friends
  • Less interest in activities and/or appearance
  • Finding alcohol among their things or smelling alcohol on their breath
  • Slurred speech
  • Coordination problems
  • Memory and/or concentration problems

While most are aware of the dangers associated with drinking and driving, many do not realize that alcohol is even more hazardous on the water than on land.

Federal Boating Under the Influence (BUI) laws apply to ALL boats from canoes to cargo ships but it is not just the boat operator who is at risk for the dangers associated with drinking while on the water. Recreational boat passengers are just as likely as operators to die as a result of drinking alcohol. A primary reason for this is that most boating fatalities involve falling overboard and drowning, rather than collisions. Drinking increases these risks to the passengers, even if the operator has not been drinking.

PAS System’s portable breathalyzers provide the ability to conveniently test your breath alcohol content no matter where the party’s at. 

Alcohol Effects
Alcohol has many physical effects that directly threaten safety and well-being on the water. When a boater or passenger drinks, the following occur:

  • Cognitive abilities and judgment deteriorate, making it harder to process information, assess situations, and make good choices.
  • Physical performance is impaired- evidenced by balance problems, lack of coordination, and increased reaction time.
  • Vision is affected, including decreased peripheral vision, reduced depth perception, decreased night vision, poor focus, and difficulty in distinguishing colors.
  • Inner ear disturbances can make it impossible for a person who falls into the water to distinguish up from down.
  • Alcohol creates a physical sensation of warmth-which may prevent a person in cold water from getting out before hypothermia sets in.

Alcohol Info

Alcohol In The Body

What kind of substance is alcohol?
Alcohol is classified as a depressant because it slows down the central nervous system, causing a decrease in motor coordination, reaction time and intellectual performance. At high doses, the respiratory system slows down drastically and can cause a coma or death.

How does alcohol move through the body?
Once swallowed, a drink enters the stomach and small intestine, where small blood vessels carry it to the bloodstream. Approximately 20% of alcohol is absorbed through the stomach and most of the remaining 80% is absorbed through the small intestine.

Alcohol is metabolized by the liver, where enzymes break down the alcohol. Understanding the rate of metabolism is critical to understanding the effects of alcohol. In general, the liver can process one ounce of liquor (or one standard drink) in one hour. If you consume more than this, your system becomes saturated, and the additional alcohol will accumulate in the blood and body tissues until it can be metabolized. This is why having a lot of shots or playing drinking games can result in high blood alcohol concentrations that last for several hours.

What effect does alcohol have on the body?
Having too much to drink on just one occasion can affect both your heart and brain which can lead to tragic results. Excessive drinking can also lead to emotional problems, issues with self-esteem and can negatively affect job performance as well as relationships with family and friends. 
Over time, drinking alcohol can have a serious long term negative effect on the body. 

Alcohol interferes with the brain’s communication pathways, and can affect the way the brain looks and works. These disruptions can change mood and behavior, and make it harder to think clearly and move with coordination.  


  • Cardiomyopathy – Stretching and drooping of heart muscle
  • Arrhythmias – Irregular heart beat
  • Stroke
  • High blood pressure  


  • Steatosis, or fatty liver
  • Alcoholic hepatitis
  • Fibrosis
  • Cirrhosis

Alcohol causes the pancreas to produce toxic substances that can eventually lead to pancreatitis, a dangerous inflammation and swelling of the blood vessels in the pancreas that prevents proper digestion. 

Drinking too much alcohol can increase your risk of developing certain cancers, including cancers of the:

  • Mouth
  • Esophagus
  • Throat
  • Liver
  • Breast

Immune System:
Drinking too much can weaken your immune system, making your body a much easier target for disease.  Chronic drinkers are more liable to contract diseases like pneumonia and tuberculosis than people who do not drink too much.  Drinking a lot on a single occasion slows your body’s ability to ward off infections – even up to 24 hours after getting drunk.


BAC refers to the amount of alcohol contained in a person's blood. It is measured as weight per unit of volume. Typically this measurement is converted to a percentage such as 0.10%, which indicates that one-tenth of a percent of a person's blood is alcohol.

A breath test can be used to measure the concentration of alcohol in the breath. This relates directly to the alcohol concentration in the blood, and thus provides an accurate determination of the quantity of alcohol reaching the brain.

The exchange of alcohol from the blood to the breath occurs in the alveoli of the lungs. This is also called the deep lung region. Alveoli are minute tissue sacs in the lungs that are richly supplied with blood from the heart. By diffusion, some of the alcohol molecules in the blood partition into the breath.

Because alcohol in the blood travels directly to the brain, cognitive functioning is affected, resulting in increased risk of many kinds of injuries.














It is important to know how alcohol affects the body at different levels:

DUI Laws

In all 50 states and the District of Columbia it is a crime to operate a motor vehicle with a blood alcohol concentration (BAC) at or above 0.08 percent.

Once convicted of a DUI, your license is typically suspended or revoked. In certain instances your license can be suspended even before a conviction with a procedure called administrative license suspension.  In some states, if a hardship can be demonstrated, your privileges can be restored on a limited basis such as allowing you to drive to work. 

An interlock device is a breath-testing unit that a driver must blow into before starting a vehicle. The device disables the ignition if alcohol is detected. All states have laws either requiring interlocks for certain offenders or allowing courts to order interlocks at their discretion.

The penalties for drunk driving can result in a driver’s vehicle being impounded or sold or requiring the driver to display specially marked license plates on their vehicle. 

Alcohol exclusion laws allow insurance companies to deny payment for treatment of drunk drivers’ injuries. 


Cost of a DUI

Even if you are fortunate and your DUI has not resulted in a crash, damage to property, or caused physical harm to anybody, the price you will pay is going to be high! While the fees associated with some aspects of a DUI vary by state; a routine DUI will be a financial burden no matter where you live! 

According to a survey of lawyers, police and auto clubs the average costs for a first time DUI in the USA are:

Minimum Fine.............................................$390
Penalty Assessment....................................$666
State Restitution Fund.................................$100
Alcohol-Abuse Education Fund...................$50
Blood/Breath Testing Fee............................$37
Jail-Cite-and-Release Fee...........................$10
Driving/Alcohol-Awareness School.............$375
License Reissue Fee....................................$100
Attorney Fees (average)..............................$2,500
Auto Insurance Increase (total for 3 years)..$3,600- $6,600
TOTAL COST OF A 1ST TIME DUI...............$7,828- $10,828

In addition to the costs listed above, several states also require DUI offenders to install an interlock ignition device. The cost associated with this for first time offenders ranges from $1,200 to $3,600.

Remember: These are the costs associated with a DUI that DOES NOT involve property or physical damage.




Why do I need to have my unit calibrated?
Like any other analytical instrument, breathalyzers need routine calibration to ensure their accuracy. 

Calibration is the process of checking and adjusting the internal settings of a breath analyzer by comparing and adjusting its test results to a known alcohol standard. A breathalyzer unit that is out of calibration can result in a breath alcohol concentration reading that is either lower or higher than the actual level. 

PAS Systems recommends that you have your MARS, Satellite, MARS BT or Click unit calibrated annually or after every 250 tests. Because precise calibration is crucial it can be performed only by PAS Systems International. Calibration of your personal breathalyzer unit must be performed using a NHTSA-approved wet bath simulator.
