Transcript Cocaine
In the 1880’s, psychiatrist Sigmund Freud
wrote and prescribed cocaine as a
treatment for many ailments such as
depression & addiction to alcohol and
opiates.
Pure cocaine was first isolated from the
leaves of the coca bush in 1860.
Contained in small amounts in the leaves
of erythroxylum (coca) bush
Researchers soon discovered that
cocaine numbs whatever tissue it
touches.
This lead to it’s use as a local anesthetic.
Coca leaves grow on the slopes of the
Andes Mountains in South America.
For at least 4,500 years, people in Peru &
Bolivia have chewed the coca leaves to
lessen hunger & fatigue.
Most of the world’s supply of coca is
grown & refined into cocaine in
Colombia.

Heart - Cocaine is bad for the heart.
Cocaine increases heart rate and blood
pressure while constricting the arteries
supplying blood to the heart.
Brain - Cocaine can constrict blood vessels
in the brain, causing strokes. This can
happen even in young people without
other risk factors for strokes. Cocaine causes
seizures and can lead to bizarre or violent
behavior.
Lungs and respiratory system. Snorting cocaine
damages the nose and sinuses. Regular use
can cause nasal perforation. Smoking crack
cocaine irritates the lungs and, in some
people, causes permanent lung damage.
Sexual function. Although cocaine has a
reputation as an aphrodisiac, it actually
may make you less able to finish what you
start. Chronic cocaine use can impair
sexual function in men and women. In men,
cocaine can cause delayed or impaired
ejaculation.
Psychologically
Not physiologically although withdrawal
or “coming down off drug” is extremely
difficult on the body
