Although alcohol has long been a part of human celebrations,
it is a psychoactive drug capable of causing addiction.
After being absorbed into the bloodstream,
alcohol is transported throughout the body.
The liver
metabolizes alcohol as blood circulates through it.
If people drink more alcohol each hour than the body can metabolize,
blood alcohol concentration (BAC) increases.
The rate of alcohol metabolism depends,
on a variety of individual factors.
Alcohol is a central nervous system depressant.
At low doses, it tends to make people feel relaxed.
At higher doses, alcohol interferes
with motor and mental functioning;
at very high doses,
alcohol poisoning, coma, and death can occur.
Effects may be increased if alcohol is combined with other drugs.
Chronic alcohol use has negative effects
on the digestive and cardiovascular systems and increases cancer risk and overall mortality.
Pregnant women who consume alcohol
risk giving birth to children with a fetal alcohol spectrum disorder (FASD).
Even occasional drinking during pregnancy can cause brain injury in the fetus.
Individuals can now be diagnosed with alcohol use disorder,
a category that first appeared in the DSM-5
Alcohol use disorder can be diagnosed as
mild, moderate, or severe depending on the number of criteria an individual meets over a 12-month period.
Alcohol misuse involves
drinking in dangerous situations or drinking to a degree that causes academic, professional, interpersonal, or legal difficulties.
Severe alcohol use disorder (alcoholism) is characterized by
more extensive problems with alcohol, usually involving tolerance or withdrawal.
Binge drinking is a common form of misusing alcohol that
negatively affects both drinkers and non-drinkers. For numerous reasons, college and university students may be especially prone to binge drinking.
