Unit 3: Controlling Substances
What is a drug?
• Drug- A drug is any substance (other than
food) which changes the way the body or
mind functions.
• Prescription Drug – drugs prescribed by a
medical doctor that can heal illness and
injury or take away pain.
• Drugs can come from plants or can be
made in labs. Both have the potential to
cause harm if not taken appropriately.
What is a Controlled Substance ?
• Controlled substance - a drug which has
been declared by federal or provincial law
to be illegal for sale or use, but may be
dispensed under a physician's
prescription.
• The basis for control and regulation is the
danger of addiction, abuse, physical and
mental harm (including death), the
trafficking by illegal means, and the
dangers from actions of those who have
used the substances .
Appropriate Uses of Substances
• 1. To get better if you are sick.
• 2. To reduce pain from illness or injury
under the guidance of an MD.
• 3. To manage mental illness
(i.e. depression, anxiety )
Ways in which substances
are abused
• Taking too much of a drug/alcohol at one time
(bingeing) or taking smaller doses more often.
• Taking a prescribed drug after it is no longer
needed.
• Taking a drug that has been prescribed to
someone else.
• Taking a drug to cope with everyday stress.
• Combining drugs
The Different Stages of Drug and
Alcohol Use
• Nobody wakes up one day and discovers
he or she is addicted to drugs.
• Drugs often become a part of our lives
through a slow process.
• Each time you move from one stage of
drug use to another is a result of a choice.
• The different stages are: Non-user,
Experimental Use, Regular Use, Binge
Use and Addiction
Non-Users
• They are people who don’t use any drugs,
including alcohol and tobacco. Their
reasons include
• Health Reasons
• Religious beliefs
• Athletic Ability
• Negative Past experience with drugs
• Lack of interest
Experimental Use
• Trying drugs for the first time is almost
always with other people. ( party,friends)
• This stage is very brief and is characterized
by:
– Curiosity about drugs
– A belief that doing drugs won’t lead to harm.
– A social atmosphere.
• After experimenting with a drug, a person
decides whether or not to use them again.
Regular Use
• When drugs or alcohol start to show up
more and more often.
• When you notice you are thinking about
drugs and alcohol and talking about them
a lot.
• When you realize that most of your friends
are using.
Regular Use (cont’d)
• Other qualities of regular use include:
– Using automatically without thinking about it.
– Finding it difficult to enjoy social situations
without using drugs or alcohol.
– Some areas of life are becoming affected (e.g.
school, family, money)
l
Binge Use
• Binge Use – refers to heavy and excessive
drinking or drugging on a sporadic basis,
with little or no use in between.
• Binge use is unpredictable and scary for
both the user and friends and family
members
Binge Use (cont’d)
• Problems associated with binge use
include:
– Higher levels of agression
– Fighting and violence
– Getting into serious trouble while on binge
(fighting, assault, domestic violence)
– Alcohol poisoning or drug overdose, leading
to medical treatments
– Increased risk of accidents (e.g impaired
driving)
Addiction
• This is the most frightening stage of drug
and alcohol use.
• The user experiences an utter sense of
desperation to continue using, depsite
repeated attempts to cut back and despite
negative consequences
• A person’s emotional and physical health
is greatly affected: mood swings and
serious health problems often emerge.
Reasons why people keep using
drugs
• Drug use provides an instant group of “friends”
• As people grow more and more dependent, reality
becomes harder to deal with; drugs offer an “escape”.

responsibilities.

events.
