Lesson 1 Drug Misuse and Abuse
Objectives:
• The student will be able to explain the difference between
drug misuse and drug abuse.
• The student will be able to identify the risks of drug abuse.
• The student will be able to develop strategies for making
healthful choices about taking medicines.
Vocabulary Words (7): drug, prescription medicines, over-thecounter (OTC) medicines, drug misuse, side effect, tolerance,
drug abuse
Drug Use
• There is a difference between drugs and medicines.
• A Drug- is a substance other than food that changes the
structure or function of the body or mind.
• A medicine is a drug used to prevent or treat illnesses and
disease.
• All medicines are drugs, but not all drugs are medicines.
• Both drugs and medicines can be abused.
Types of Medicines
• There are two general categories of medicine:
• Prescription medicines- medicines that can be sold
only with a written order from a physician.
• Over-The-Counter (OTC) Medicines- medicines
that are safe enough to be taken without a written
order from a physician.
Drug Misuse
• Drug misuse- taking or using medicine in a way
that is not intended.
• Examples of drug misuse:
– Using a drug without following the instructions on the
label.
– Using a drug not prescribed for you.
– Allowing someone else to use a drug prescribed for
you.
– Taking more of the drug than the doctor prescribed.
– Using the drug longer than advised by the doctor.
• Side effect- any effect of a medicine
other than the one intended.
– Common side effects include stomach
upset, drowsiness, sleeplessness and
headache.
– Side effects should be discussed with a
doctor if they happen.
• When a doctor prescribes a drug that
needs to be taken for a long period of
time a drug tolerance may develop.
– Tolerance- a condition in which a
person’s body becomes used to the
effect of a medicine and needs greater
and greater amounts of it in order for it
to be effective.
Drug Abuse
• Drug abuse- intentionally using
drugs in a way that is unhealthy
or illegal.
• Drug abuse can affect all three
sides of your health triangle.
– Physical: sleeplessness,
irritability, heart failure and
stroke.
– Mental/Emotional: interference
with brain function, trouble
thinking, concentrating,
depression, anxiety
– Social: withdrawl from family and
friends, loss of interest in school
or other activities.
Addiction
• People who abuse drugs risk
developing an addiction.
• Addiction is a physical or psychological
need for a drug.
• Process of addiction:
– Regular drug use
– Tolerance builds
– User becomes addicted
• You can’t tell how many times you
have to use the drug for the addiction
to start.
• Drug addiction is a disease, just like
alcoholism. Treatment options are
available, but it is a long and
challenging road to quit using the
drug.

Anabolic Steroids
• Anabolic Steroids- synthetic substances related
to the male sex hormones.

growth problems, lung diseases and skin
conditions.
• These steroids are similar to the male hormone
testosterone

adding muscle mass and increasing strength and
endurance.

high blood pressure, kidney tumors, severe acne,
trembling.
– Males: shrinking of testicles and breast
development
– Females: growth of facial hair, menstrual changes

Anabolic Steroids
Abuse of these drugs has become a serious concern
in professional sports in the US.
A study asked athletes the following question: If
you were given a pill that would guarantee you a
gold medal but the side effect was that the drug
would kill you within "three years" after winning
the gold medal, would you take it?
65% said yes they would take the pill anyway.
Teens and Steroid Use
• Most teens avoid using steroids.
• Those who do choose to use
them risk damaging their health
and negatively affecting their
appearance (acne, hair loss,
stunting of growth)
• Can also cause mood swings
which can cause someone to
become angry and violent (Roid
Rage)
• Because teens are still growing
and developing, the hormonal
imbalance steroids cause can
lead to problems like the ones
listed on the previous slides.
