Types of Drugs and Their
Effects
Lesson 2, Chapter 10
Drug Use and the Body
All drugs affect the body in some way, but the same drug can
affect people differently.
Some drugs are more harmful than others. When a person uses a
drug over time, he or she can develop a tolerance to the drug.
Tolerance: the body’s need for larger and larger amounts of a drug
to produce the same effect.
Overdose: taking more of a drug than the body can tolerate.
Types of Drugs
There are many types of drugs, including:
Stimulants
Depressants
Club drugs
Narcotics
Hallucinogens
All of them can be harmful to your physical,
mental/emotional, and social health.
Stimulants
Caffeine is a stimulant found in foods and drinks such as chocolate, coffee, tea, and some
soft drinks (soda).
Have you ever had a soda near bedtime and then couldn’t fall asleep?
Stimulant: a drug that speeds up the body’s functions.
Physical
 Heart Rate
 Breathing Rate
 Raises blood pressure
Mental/Emotional
 Gives a false sense of energy, well-being, confidence, power
In time, these effects wear off, and the user often feels exhausted and irritable.
Stimulants
Amphetamines: strong stimulant drugs that speed up the nervous system.
 Sometimes prescribed to treat certain medical conditions. (ADD and ADHD)
 Often called “speed”
 They come in different forms that may be swallowed, inhaled, smoked, or injected
“Crystal meth” is the street name for methamphetamine = an extremely addictive drug
that can cause a person’s heart to suddenly stop working.
Cocaine is an illegal stimulant made from the coca plant. Can be inhaled through the
nose, smoked, or injected into the veins. (also known as “blow,” “snow,” or “coke.”)
 Produces a brief feeling of well-being and confidence, but after it wears off the user
feels anxious
Depressants
Depressants: drugs that slow down the body’s functions and reactions, including heart
and breathing rates.
Depressants work by slowing down a person’s motor skills and coordination.
 During use: Can affect a person mentally and emotionally by giving the user a false
sense of well-being through reduced anxiety and relaxation.
 After use: user may experience mood swings and depression.
Most depressants come in tablet or capsule form.
Depressants are legal when prescribed by a doctor to treat certain conditions
 EX: Anti-anxiety and Sedatives
*Alcohol is a depressant!
