Alcohol Information

Effects of Alcohol

Alcohol affects people differently, depending on their size, sex, body build, and metabolism. General effects of alcohol are a feeling of warmth, flushed skin, impaired judgment, decreased inhibitions, muscular incoordination, slurred speech, and memory and comprehension loss. In states of extreme intoxication, vomiting is likely to occur, possibly accompanied by incontinence, poor respiration, a fall in blood pressure, and in cases of severe alcohol poisoning, coma and death.

Results of Heavy Alcohol Use

Drinking heavily over a short period of time usually results in a “hangover”— headache, nausea, shakiness, and sometimes vomiting, beginning from 8 to 12 hours later. A hangover is due partly to poisoning by alcohol and its other ingredients and partly to the body’s reaction to withdrawal from alcohol.

Mixing Alcohol with Other Drugs

Combining alcohol with other drugs can make the effects of the other drugs much stronger and more dangerous. Many accidental deaths have occurred after consuming alcohol combined with other drugs. Cannabis, tranquilizers, barbiturates and other sleeping pills, or antihistamines (in cold, cough, and allergy remedies) should not be taken with alcohol. Even a small amount of alcohol with any of these drugs can seriously impair a person’s ability to drive a car.

Tolerance

People who drink on a regular basis become tolerant to many of the unpleasant effects of alcohol, and thus are able to drink more before suffering these effects. Yet even with increased consumption, many such drinkers don’t appear intoxicated. Because they continue to work and socialize reasonably well, their deteriorating physical condition may go unrecognized by others until severe damage develops— or until they are hospitalized for other reasons and suddenly experience alcohol withdrawal symptoms.

Psychological dependence

Psychological dependence on alcohol may occur with regular use of even relatively moderate daily amounts. It may also occur in people who consume alcohol only under certain conditions, such as before and during social occasions. This form of dependence refers to a craving for alcohol’s psychological effects, although not necessarily in amounts that produce serious intoxication. For psychologically dependent drinkers, the lack of alcohol tends to make them anxious and, in some cases, panicky.

Physical dependence  

Physical dependence occurs in consistently heavy drinkers. Since their bodies have adapted to the presence of alcohol, they suffer withdrawal symptoms if they suddenly stop drinking. Withdrawal symptoms range from jumpiness, sleeplessness, sweating, and poor appetite, to tremors (“the shakes”), convulsions. hallucinations. and sometimes death.

Alcohol abuse can take a negative toll on the drinker’s life, fostering violence or a deterioration of personal relationships. Alcoholic behavior can interfere with school or career goals and lead to unemployment.

Long-term alcohol abuse poses a variety of health risks, such as liver damage and increased risk of heart disease. Fetal Alcohol Syndrome may result when a pregnant woman drinks alcohol; this condition causes facial abnormalities in the child, as well as growth retardation and brain damage, which often is manifested by intellectual difficulties or behavioral problems.

The effects of any drug depend on several factors:

• The amount of the drug taken at one time
• The user’s past drug experience
• The manner in which the drug is taken
• The circumstances under which the drug is taken (the place, the user’s psychological and emotional stability, the presence of other people, the concurrent use of other drugs, etc.)

It is the amount of alcohol in the blood that causes the effects. In the following list, the number denotes the amount of alcohol in milligrams in each deciliter of blood—that is, the blood alcohol concentration, or BAC. (For example, an average person may get a blood alcohol concentration of 50 mg/dL after two drinks consumed quickly.) Following the BAC is a description of the usual effects of these amounts on people who have not developed a tolerance to alcohol.

Blood Alcohol Concentration (mg/dL) Effect:

BAC (mg/dL)Alcohol Effects:

• 50 - Feeling of warmth, skin flushed; impaired judgment; decreased inhibitions
• 100 -  Obvious intoxication in most people. Increased impairment of judgment, inhibition, attention, and control; some impairment of muscular performance; slowing of reflexes
• 150 - Obvious intoxication in all normal people. Staggering gait and other muscular incoordination; slurred speech; double vision; memory and comprehension loss.
• 250 -  Extreme intoxication or stupor. Reduced response to stimuli; inability to stand; vomiting; incontinence; sleepiness
• 350 - Coma. Unconsciousness; little response to stimuli; incontinence; low body temperature; poor respiration; fall in blood pressure; clammy skin
• 500 - Death likely
