Blood alcohol concentration (BAC), also known as blood alcohol level, expresses the amount of alcohol in the blood.
The chemical name for alcohol is ethanol or ethyl alcohol. This intoxicating ingredient is found in:
- Distilled spirits
When you consume an alcoholic beverage, your small intestines and stomach absorb most of the alcohol. From here, alcohol enters your bloodstream. Since alcohol is a toxin, your liver metabolizes alcohol so it is filtered out of your blood.
If you consume alcohol more rapidly than your liver is able to process the substance, blood alcohol concentration increases. When this occurs, you might start feeling the effects of intoxication, informally known as drunkenness.
The liver is capable of processing one standard drink per hour. According to NIAAA (National Institute on Alcohol Abuse and Alcoholism), a standard drink is:
- 12oz beer (5% alcohol content)
- 5oz wine (12% alcohol content)
- 1.5oz distilled spirits (40% alcohol content)
Blood alcohol levels are influenced by many situational and physical variables, including:
- Body fat percentage
- Body chemistry
- Alcohol content of beverages consumed
- Spacing of drinks
- Time since last alcoholic drink
- Prescription medications
- Illicit drugs
All of the above factors can impact BAC levels and also the extent of impairment caused by alcohol.
WHAT HAPPENS TO YOUR BODY AT DIFFERENT LEVELS OF BLOOD ALCOHOL CONCENTRATION?
This is how different blood alcohol concentration levels can affect your body and mind:
BAC LEVEL: 0.0%
There is no alcohol in your blood and you are sober.
BAC LEVEL: 0.02%
You will start to feel relaxed with some reduction in judgment and multitasking abilities.
Alcohol at this level starts to exert some mood-altering effects, too.
BAC LEVEL: 0.05%
Alertness levels reduce at this BAC level. Your judgment will be further impaired and you will feel less inhibited.
At this blood alcohol concentration level, you will find it harder to track moving objects, making it dangerous to drive.
Response times will decrease when your BAC level reaches 0.05%.
BAC LEVEL: 0.08%
You will lose muscle coordination and balance at these BAC levels.
Driving at these BAC levels is dangerous as you will have difficulty regulating speed and you will struggle to react quickly enough to emergency situations.
Judgment and reasoning are both impaired. You are at increased risk of injuries.
BAC LEVEL: 0.10%
Reaction times are impaired, your thinking and speech are slurred.
BAC LEVEL: 0.15%
Altered mood, loss of balance, nausea, and vomiting are commonplace reactions to BAC levels of 0.15%.
BAC LEVEL: 0.15% TO 0.30%
The most common physical effects at these BAC levels are:
DEADLY BAC LEVELS
After 0.3% BAC, alcohol will have such a high concentration in your blood that it can cause deadly consequences and lead to life-threatening problems. Lethal blood alcohol concentration levels are not something to take lightly, learn more about these below and get a better idea of what you can do to help someone who is struggling.
BAC LEVEL: 0.30% TO 0.40%
This range of blood alcohol concentration is liable to trigger alcohol poisoning, also known as alcohol overdose. This can bring about a loss of conscious and can be life-threatening.
BAC LEVEL: OVER 0.40%
BAC levels over 0.4% are potentially lethal, potentially involving:
- Respiratory arrest
If you are drinking and believe that someone you’re with may be at deadly blood alcohol levels, contact emergency services immediately and get help. Ignoring this can lead to disastrous consequences.
Moreover, if someone who is dealing with dangerous high levels of BAC, it can be a strong sign that they are an alcoholic or have alcoholic tendencies. Reach out to an addiction treatment program, like Gratitude Lodge and get the help you need today.
HOW LONG DOES IT TAKE FOR BAC LEVELS TO DECREASE?
Alcohol has a half-life of between four and five hours. After this point, you will have no alcohol in your system.
The following tests can detect alcohol in your system:
- Blood test: 12 hours
- Breath test: 24 hours
- Urine test: 12 hours
- Saliva test: 48 hours
- Hair test: 90 days
