A brief overview of alcohol:
Alcohol is the most abused drug in the United States.
"Alcohol" is the name given to a family of closely related and naturally occurring
chemicals. Each of the chemicals that is called an "alcohol" contains a molecule
chemists refer to as a "hydroxy radical." This radical contains one oxygen atom and
one hydrogen atom bonded together. The simplest alcohol has only one carbon atom,
three hydrogen atoms, and one hydroxy radical. The next alcohol has two carbon
atoms, five hydrogen atoms and one hydroxy radical. The third alcohol has three
carbon atoms, seven hydrogen atoms and one hydroxy radical. That is how the alcohols
differ from one another.
Alcohols are molecularly very similar and produce similar effects. They produce
intoxicating effects when ingested into the human body. Only one of them is meant for
human consumption. However, when ingested in substantial quantities it can cause
death.
