3. Introduction
to
Pharmacology
The study of drugs or chemicals and the
effects they have on living animals is called
pharmacology. Pharmacology explains
what drugs are, what they do to body
functions and what the body does to
them.

5. A drug is any substance (with the
exception of food and water) which,
when taken into the body, alters the
body’s function either physically
and/or psychologically. Drugs may
be legal (e.g. alcohol, caffeine and
tobacco) or illegal (e.g. cannabis,
ecstasy, cocaine and heroin)

7. Psychoactive drugs affect the central nervous
system and alter a person's mood, thinking and
behavior . Psychoactive drugs may be divided
into four categories: depressants, stimulants,
hallucinogens and 'other'.

9. Our bodies are largely controlled by proteins. Proteins exist in
many different forms in the body and have many different
functions. Each protein has a specific function and is quite specific
to the cell type that it acts on. For example, there are specific types
of proteins called receptors. In order for a drugs to exert an effect
it needs to be bound to a protein. This can be thought of as a lock
and key system; where the drugs are the key and the protein is the
lock. Drugs that produce a change in the cell functioning are called
agonists. drugs that stop a normal function of the cell are called
antagonists.

17. ◦ Alcohol is glorified in
movies, music and
television. Everyone has
watched movies or
shows featuring
college drinking parties
and feats involving
massive amounts of
alcoholic beverages
17
18. Many college
students can also
set their
schedules so they
have classes only
a few days a week,
leaving three- and
four-day
weekends open
for partying and
recovering.

19. Some marketing
campaigns
seem to be
targeting this
young age as
well, featuring
fruity and
sugary, good-
tasting alcoholic
beverages.

◦ Another dangerous trend popping
up on college campuses is the
mixing of alcohol with energy
drinks for a different kind of buzz.
This can be even more dangerous
than the alcohol alone due to the
caffeine or other stimulants found
in the energy drink which can mask
the depressant effect of alcohol.

Aside from the health risks of abusing alcohol, like damage to the liver and
heart, the National Center on Addiction and Substance Abuse at Columbia
University, or CASA, ran a study that found that more than 1,700 students die
every year from alcohol-related injuries, including alcohol poisoning. Similarly,
CASA also found that alcohol played a role in 100,000 rapes or sexual assaults
and 700,000 reported cases of assault.
24. 24
Driving under the
influence and
alcohol-related
crimes are other risk
factors for alcohol
abuse. Studies have
also shown that
when drinkers start
young,
they have a higher
tendency to develop
a dependence
25. Because of drugs becoming more and more common the
students are becoming victims of mental illness

• Harm to organs and systems in your body,
such as your throat, stomach, lungs, liver,
pancreas, heart, brain, nervous system
cancer (such as lung cancer from inhaling

equipment and increased
• Harm to your baby, if you are pregnant

◦ The college years are some of the
most popular times to
experiment with alcohol.
Roughly 80 percent
of college students – four out of
every five – consume alcohol to
some degree. It's estimated that
50 percent of those students
engage in binge drinking, in an
attempt to get drunk, which
involves consuming too
much alcohol in too little time.
College students are traditionally
between 18 and 22 years old.
35. ◦ Learn to Deal With Life’s
Pressures:-The inability to
deal with normal life
pressures is one of the
major reasons that drive
people to drugs and alcohol
35
36. 36
Don’t Give in to Peer
Pressure:-
The inability to deal with
normal life pressures is one
of the major reasons that
drive people to drugs and
alcohol
37. 37
◦ Research indicates that people
who share a close relationship
with their families are less likely
to become drug addicts. The
guidance and support provided
by the family makes it easier for
a person to deal with life
pressures and stay away from all
types of harmful substances. The
same is true for having a close
relationship with good friends
that are responsible and
trustworthy.
Develop Close Family Ties
38. ◦ Eating a balanced diet and exercising
regularly is another way of preventing
drug and alcohol addiction. Being
healthy and active makes it easier for
people to deal with life stresses. This in
turn, reduces the temptation to rely on
drugs and alcohol to deal with stress. A
healthy diet and regular exercise
promotes feel good chemicals in the
brain.

Develop Healthy Habits

If the young people are aware of the harmful effects of drugs abuse ,they
would avoid drugs abuse at the first instance. Hence, drug abuse preventive
programme , If implemented effectively at schools and colleges ,can become
the most successful method to reduce it.
“Drugs take you to hell, disguised as heaven.”
“Addiction is a family disease ,one
person may use, but the whole family
suffers.”
YELLOW PART REFERS TO NORMAL FUNCTIONING OF BRAIN WHLE THE BUE ART REFERS TO ABNORMAL FUNCTIONING OF BRAIN . So the 2nd and 3rd picture shows how a brain is recovering from cocaine addiction. The first one is of 10 days and other is of 100 days . As you can see the brain isn’t fully recovered.
