Drug Vocabulary
(Chapter 17)
• Drug: any chemical that causes a change in a
person’s physical or psychological state.
• Tolerance: Your body’s ability to resist a drug.
As your tolerance increases, you need more of
the drug to produce it’s original effect.
• Overdose: the taking of a larger amount of a
drug than a person’s body can handle. Can
result in a coma, brain damage, and death.
• Impurities: illegal drugs are not regulated by
law. There is no guarantee that they are pure.
Often the are contaminated with other
chemicals.
• Drug Addiction: the uncontrollable use of a
drug. There are 2 types:
– Physical Addiction: when the body needs the drug
– Psychological Addiction: when the mind needs the
drug
• Withdrawal: the process when the drug is taken
away from the addicted person.
• Detoxification: the process by which the body
rids itself of drugs.
• Side Effect: Any effect caused by the drug that
is unintended. Effects can be physical or mental.
• Drug Interaction: When you take more than
one drug at a time, the drugs may interact in
different ways than when taken alone. 2 types of
interactions:
– Antagonism: drug is cancelled out or reduced
effectiveness
– Synergism: Interaction creates a greater effect than it
would if taken alone.
