Myth Medicines from a drugstore can’t harm you.
Fact Medicines can be just as dangerous as “street
drugs” if they are used inappropriately.
•What other myths do teens believe about drugs?
Slide 17 of 32
Section 17.1 Legal and Illegal Drugs
Facts About Drug Use
• If drugs are not used as directed, serious health
problems can result.
• Medicines are legal drugs that help the body fight
injury, illness, or disease.
• Medicines can be classified into two groups: overthe-counter drugs and prescription drugs.
Slide 18 of 32
Section 17.1 Legal and Illegal Drugs
Over-the-Counter Drugs
• A medicine that is sold legally in pharmacies and
other stores without a doctor’s prescription is called
an over-the-counter drug.
• Any over-the-counter drug can cause harm if the
instructions on the label are not followed.
Slide 19 of 32
Section 17.1 Legal and Illegal Drugs
Prescription Drugs
• A drug that can be obtained only with a written order
from a doctor and can be purchased only at a
pharmacy is known as a prescription drug.
• Prescription drugs require more government control
than over-the-counter drugs because of their
potential for harm.
Slide 20 of 32
Section 17.1 Legal and Illegal Drugs
Illegal Drugs
• An illegal drug is a chemical substance that people
of any age may not lawfully manufacture, possess,
buy, or sell.
• Illegal drugs are also called street drugs.
Slide 21 of 32
Section 17.1 Legal and Illegal Drugs
Drug Misuse
• The improper use of medicines—either prescription
or over-the-counter drugs—is called drug misuse.
• Examples of drug misuse include
• taking more than the prescribed amount of a drug
• taking drugs with the wrong foods or at the wrong
time of day
• not taking a drug for the correct period of time
Slide 22 of 32
Section 17.1 Legal and Illegal Drugs
Drug Abuse
• When a drug is intentionally used improperly or
unsafely, it is known as drug abuse.
• Drug abuse occurs when people intentionally use
any kind of drugs for nonmedical purposes.

Slide 24 of 32
Section 17.1 Legal and Illegal Drugs
Drug Abuse and the Brain
• A mood-altering drug, also called a psychoactive
drug (sy koh AK tiv), is a chemical that affects brain
activity.
• Most abused drugs are psychoactive.
Slide 25 of 32
Section 17.1 Legal and Illegal Drugs
The “Reward Pathway”
• Many psychoactive drugs trigger activity along a pathway
of cells in the brain called the “reward pathway.”
• Brain cells along the activated reward pathway release a
chemical called dopamine (DOH puh meen).
• The extra dopamine released during drug use can cause
the user to ignore the harmful effects of the drug and want
to continue using it.
• Flooding the reward pathway with dopamine may lead to
intense cravings for the drug.
• After a time, drug abuse can dull the brain’s reactions to
natural levels of dopamine.

Slide 36 of 32
Section 17.1 Legal and Illegal Drugs
Tolerance and Dependence
• When a person uses a drug repeatedly, the body
may develop tolerance to the drug.
• Tolerance may lead to drug dependence—the body
develops a chemical need for the drug and can’t
function normally without it.
Slide 37 of 32
Section 17.1 Legal and Illegal Drugs
Withdrawal

Slide 38 of 32
Section 17.1 Legal and Illegal Drugs
Drug Interactions
• When a person takes more than one drug at a time,
the drugs may interact in different ways than when
taken alone.
• Antagonism A drug antagonism
(an TAG uh niz um) occurs when each drug’s effect is
canceled out or reduced by the other.
• Synergism A drug synergism (SIN ur jiz um)
occurs when drugs interact to produce effects
greater than those that each drug would produce
alone.
Slide 39 of 32
Section 17.1 Legal and Illegal Drugs
Impurities
• Many illegal drugs are contaminated with chemicals
that may themselves be harmful or cause dangerous
drug interactions.
• Illegal drugs may vary widely from batch to batch in
the concentration of psychoactive chemicals
they contain.
Slide 40 of 32

inject drugs, contaminated blood left in the needle
can carry disease-causing viruses from user to user.

pregnant woman places her baby at risk for a broad
range of developmental problems.

Amphetamines
• Amphetamines (am FET uh meenz) are
prescription drugs that are sometimes sold illegally
as “speed” or “uppers.”
• Amphetamine abuse produces feelings of well-being
and high energy.
• The effects wear off quickly and the abuser is often
left feeling depressed.
Slide 48 of 31
Section 17.1 Legal and Illegal Drugs
Methamphetamine

Hallucinogens
• A hallucinogen (huh LOO sih nuh jun) is a drug that
distorts perception, thought, and mood.
• Hallucinogens overload the brain with sensory
information, causing a distorted sense of reality.

diethylamide, or LSD.
Psilocybin
• Another hallucinogen is psilocybin
(sil uh sy bin)—sometimes called “shrooms.”
PCP
• One of the most dangerous of all drugs is PCP, short
for phencyclidine.
• Because the drug eliminates the sensation of pain,
abusers may unintentionally injure or even
kill themselves.

Marijuana
Marijuana
(mar uh WAH nuh) is
the leaves, stems,
and flowering tops of

• The effects of club drugs and inhalants are extremely
unpredictable and dangerous.
• Abuse of steroids causes lifelong damage to the
body and brain.
