What is a Drug?
_____________– any chemical other than food intended to affect the structure or
function of the body.
Why some people use Drugs?
Many people believe that every problem, no matter how large or small, has or should
have chemical solutions.
Examples:
For fatigue = caffeine
For insomnia = sleeping pills
For anxiety or boredom = alcohol/drugs
How do drugs work???
Nerve cells in the brain are called neurons. These neurons "talk" to each other by
passing chemicals back and forth, just like passing notes in class. The neurons' "notes"
are called neurotransmitters, and they are manufactured in vesicles in the nerve cell.
Neurotransmitters include serotonin, acetylcholine, norepinephrine, dopamine, histamine
and about two dozen others.
The nerve cells are separated by a small space called a "synapse." When a message
moves down the axon of the pre-synaptic neuron, neurotransmitters are released from the
vesicle. These chemicals (or notes) cross the synapse to the post-synaptic neuron, where
they bind with receptors specifically designed to receive them, much as a key is designed
to fit into a specific lock.
Many nerve cells have receptors that are sensitive to various drugs. These drugs
operate on the "lock-and-key" principle, where the drug can be thought of as the "key"
that either (1) fits into the "lock," causing the nerve cell (neuron) to discharge its
chemicals, or (2) "jams" the lock, preventing the nerve cell from discharging.
How do drugs work???
Ex.) -Narcotics mimic endorphins and lock into opiate receptor sites.
- Hallucinogens mimic serotonin
- Cocaine blocks the re-uptake of neurotransmitters → causing severe
depression when coming down.
- Methamphetamines cause the release
of neurotransmitters in greater amounts
- THC mimics anandamide and interferes with the cannabinoid receptor sites.
Health Consequences of Drug Use
_______________________- Once a drug enters the bloodstream, it can harm a user’s
brain, heart lungs, and other vital organs.
__________________________- drugs cloud reasoning and thinking, and users lose
control of their behavior. (lose sight of values)

Dangers of substance abuse
Some drugs have side effects –
 can range from minor to deadly.

monitoring these substances for quality, purity, or strength.
Overdose –

when alcohol and other drugs are combined.
When drug abuse involves injecting substances through a needle, hepatitis B or HIV
can occur

pregnancies
Risk to unborn and newborns:
1. breast milk – can pass from mother to infant.
2. Can cause miscarriage or premature birth
3. Can cause birth defect, mental retardation
CLASSIFICATIONS OF DRUGS
