Drug Abuse
Like perscription drugs, illegal drugs are powerfull substances. People use drugs for
mind altering reasons. Illegal drugs can change the way the brain normally works. When
some who uses drugs there judgement,thinking,feelings and actions change along with
there apperiance. When pepole use cocaine for the first time they enjoy the "high". After
using cocain over time you begin to lose weight because the effects of the drug cause you
to lose your appetit. You also find your self having trouble sleeping and you are often in a
bad mood.
Illegal drugs also can cause unwanted side effects. These effects are different with each
person: these effects include upset stomach,dizzenes,drowsiness,headache,vomiting,or
vision problems.No one can predict the negetive effects drugs can have on a persons body.
If someone takes a drug for over a long period off time, the person can develope an
addiction. If a person becomes addicted the person can develope psychological or mental
dependence on the drug.With psychological dependence, a person feels the need to keep
on taking the drug in order to get the effect they want.With physical dependence,a person
the person who stops taking the drug will suffer withdrawl symptoms which means the
person will feel uncomfotable and sick. also sometimes pepole can develope both
psycological and phisical dependece on a drug.

spinal cord make up the central nervous system, the central nervous system is involved in
almost every task that your body performs. Illegal drugs such as cocaine and marajuana
cause the brain to recieve information incorrectly and then the brain will respond with
incorrect information. If two pepole take the same drug they will react differently even if
you misuse a drug the two pepole will still react differnetly. This happens because the drug
changes the central nervous system, how fast these changes occurs depends on the,drug
