intestine.

body.
5. Brain: alcohol reaches the brain.

rate of about 0.5 oz per hour. Alcohol is
converted into water, carbon dioxide and
energy.
Inhalants
use
Effects of Inhalants on the Nervous
System

When vapors are inhaled (1), they are absorbed
through the lungs (2) and enter the bloodstream (3).
Once in the bloodstream, the chemicals travel to the
brain (4) and other tissues throughout the body. Most
inhalants that are abused depress the functioning of
the nervous system. However, the effects of
each inhalant are difficult to
determine because
each product
is made up many different
chemicals and each person may breathe in
different amounts of each
chemical.
Nevertheless, these chemicals do have significant
effects on the nervous system.
The immediate effects of inhalants
