Cocaine comes from the leaves of the tropical coca plant. It's a
double-acting drug - a powerful stimulant that speeds up your central nervous
system and an anesthetic that numbs whatever it touches, such as the inside of
your nose.
Cocaine is usually sold as white, crystalline powder that is inhaled
("snorted") from spoons or through straws. It can be injected and, in some forms
smoked.
Injecting the drug produces a powerful, fast response that peaks in minutes
and disappears within an hour.
Freebase and crack are both smokable forms of cocaine and carry a kick
similar to injecting the drug. Freebase gives an intense high lasting 2 to 5
minutes, which quickly fades into a restless desire for more of the drug. Crack
- rock-like chunks of impure freebase - also jolts your body with a short rush
of energy.
Basically, cocaine overworks your body and brain. It sends the body into
overdrive - boosting your heart rate, blood pressure, and body temperature.
Its action in the brain can make you feel alert, energetic, more sociable,
confident, and in control. This feeling can be so powerful and pleasurable that
many users immediately want more drug. For others, it isn't like that at all:
they feel withdrawn, anxious, or even panic-stricken.
More of the drug makes the pleasure - or panic - stronger. Eventually, if you
use cocaine often and long enough, the "high" gives way to paranoia (suspecting
"enemies" everywhere), hallucinations (seeing and hearing "things"), and an
unwell feeling because you can't sleep and don't feel like eating.
For may who use it once in a while, cocaine isn't a health problem. But for
some occasional users, and for those who use it frequently - especially if they
inject or smoke it - it can get to be a serious problem. Here's why:
- Damage to the heart tissue and rapid heartbeat can cause heart failure and
sudden death even though you are otherwise healthy.
- A cocaine-triggered rise in blood pressure can explode weakened blood
vessels in the brain, causing a stroke.
- It's easy to overdoes on crack, freebase, or injected cocaine - even on
small amounts of the drug. You can die from convulsions, heart failure, or the
depression of vital brain centres that control breathing.
- Those who inject cocaine also run the risk of infections from dirty needles
and impurities in the drug, and of hepatitis or AIDS if they share needles with
others.
- Those who smoke cocaine risk damaging their entire breathing system.
- Finally, as with other stimulant drugs, heavy or long-term use can simply
cause the body o burn itself out. Insomnia, weight loss, and malnutrition are
among the first signs of a serious problem.
Yes.
It is true that fewer than one in ten people who have ever tried cocaine
continue to use it once a week or more. However, some regular users, chasing a
longer and stronger high, keep increasing their dose. For those who do get
hooked, cocaine seems to be one of the hardest drug habits to shake.
Regular, heavy users find that when the high fades, it is followed by a low
as the central nervous system rebounds and works more slowly than normal. It's
called the "crash" - a nagging depression that sends many users back for more of
the drug.
