What exactly are drugs?They are substances, other than food,
that affect a person’s mental, emotional, or physical state
A person who uses drugs is not usually trying to cause damage to his
or her brain, lungs, or other vital organs, however, many drugs have
harmful side effects, and such damage can occur

Making decisions about drugs Legal and illegal mood-altering drugs are
increasingly available in Canada and the pressure to use such drugs are widespread
This is especially true in young people, who are experimenting with new levels of independence and
responsibility, and who may experience pressure from friends, peers, the media, and other sources
You need good information to make good conscious decisions
People with good information are more likely to make sound decisions, and they will pass this information
on to their friends as well

Types of DrugsMood-altering drugs affect the body’s central
nervous system, which sends information about what we are sensing or feeling to the
bodyMarijuana Hallucinoge
nsDepressants Stimulants
Anabolic Steroids

Marijuana (Cannabis)Marijuana, the most popular form of
Cannabis, is placed in a class of its own because it acts mostly as a
hallucinogen, but also has depressant effects (slows response
time and affects memory) and a stimulant effect (raises your heart
rate)

HallucinogensThese alter users’ perceptions of the world around them, causing distortions in the way
they sense their surroundingsWhile overdoses are rare, these drugs can pose a risk of accidents and injuries because
they distort what the user experiencesUsers may also experience flash backs later
in lifeHallucinogens include LSD, Magic Mushrooms, mescaline, and ecstasy

DepressantsThese slow down the Central Nervous
System and reduce inhibitionsLike stimulants, many depressants can be
easy to obtain; however, this does not make them harmless
Examples of depressants are alcohol, solvents (glue or gasoline), opiates
(heroin), pain killers, tranquilizers , and sleeping pills
![Page 8: DRUG USE & ABUSE](https://reader031.fdocuments.net/reader031/viewer/2022031922/56815ff3550346895dcef26b/html5/thumbnails/8.jpg)
StimulantsThese speed up the body systems such as the
Central Nervous System and the Cardiorespiratory System, delay fatigue, and
may produce hyperactivitySome stimulants are prescribed for certain
medical conditions Common stimulants include nicotine, caffeine, diet pills, Ritalin, cocaine, crack,
speed, methamphetamine, and other so-called “club-drugs”
![Page 9: DRUG USE & ABUSE](https://reader031.fdocuments.net/reader031/viewer/2022031922/56815ff3550346895dcef26b/html5/thumbnails/9.jpg)
Anabolic SteroidsThese are commonly used to treat medical
conditionsNon-medically, steroids can help increase training endurance and build muscles, and so
people use them to enhance athletic performance and body image
They are a controlled substance, meaning using them without a prescription is illegal
Anabolic steroid use is linked to a range of problems, both physical and psychological,
which may continue even after a person stops using steroids

Weighing the Hazards ofSubstance Abuse
Using drugs for non-medical reasons almost always poses
a degree of risk…Risk can range from very low to very high, & harm can occur even
if it is your 1st time!
![Page 11: DRUG USE & ABUSE](https://reader031.fdocuments.net/reader031/viewer/2022031922/56815ff3550346895dcef26b/html5/thumbnails/11.jpg)
Levels of Use1 – Non-Use: It is estimated 1/3 of young Canadians choose not to use tobacco, alcohol, or any illegal substance. This is obviously the healthiest choice because
it involves 0 risk!2 – Experimental Use: This occurs because of curiosity and may not occur
again. The risk is usually low, but it depends on several factors; the drug taken, how it is taken, how much of it is taken; the user’s personality, mood,
expectations, and surroundings. The risk can be higher for inexperienced users, who may accidently take too much or not know how to handle the drug’s effects3 – Social Use: This is ongoing drug use with moderate consumption. The risk can be low to moderate depending on the particular drug and how it is used.
4 – Binge Use: This is use of a large amount of a substance at one time. Even on a single occasion the risk of harm is high
5 – Frequent, heavy use: This is ongoing drug use that leads to problems in one or more areas of a person’s life (study, work, friendships, family relations). Risk
of significant and lasting harm is high6 – Dependent Use: This is compulsive and excessive drug use that continues
despite problems in various life areas (employment, relationships, etc.). Risk is significant and lasting harm is very high

Drug use and abuse can effect us in many ways…Even use of drugs that are readily
available can have a major negative effect on our way of life.
Drugs can….- Pose a safety concern
- Can lead to long-term physical health problems
- Can lead to mental health problems- Can lead to cognitive problems
- Lead to violence and crime
Effects of Drug Use
![Page 13: DRUG USE & ABUSE](https://reader031.fdocuments.net/reader031/viewer/2022031922/56815ff3550346895dcef26b/html5/thumbnails/13.jpg)
Safety ConcernsMost substances affect the users judgment and motor coordination
Intoxication can cause users to make unsafe choices
This makes any kind of physical activity very dangerous
![Page 14: DRUG USE & ABUSE](https://reader031.fdocuments.net/reader031/viewer/2022031922/56815ff3550346895dcef26b/html5/thumbnails/14.jpg)
Long-term physical health problems
Introducing a foreign substance into the body on a regular basis may have long
term physical effectsThe risks of using a substance like
tobacco decrease greatly when a person stops using them, however, with other
substances, such as methamphetamine, it is not clear whether the effects are
reversibleStill, with other substances, such as
Anabolic Steroids, some of the effects are clearly not reversible
![Page 15: DRUG USE & ABUSE](https://reader031.fdocuments.net/reader031/viewer/2022031922/56815ff3550346895dcef26b/html5/thumbnails/15.jpg)
Mental Health ProblemsCasual use of some drugs such as
amphetamines, ecstasy, and crystal meth can cause short term anxiety and other negative
feelingsLonger-term use can lead to more serious
mental health problemsPeople with mental health problems often use
substances to “self-medicate” their condition, but this is obviously self-defeating because the highs and lows of intoxication will likely
aggravate mental health problems
![Page 16: DRUG USE & ABUSE](https://reader031.fdocuments.net/reader031/viewer/2022031922/56815ff3550346895dcef26b/html5/thumbnails/16.jpg)
Cognitive ProblemsSome substance use has a clear effect on the way users perceive and understand what
is going oneFor example, even short-term use of cannabis, cocaine, and ecstasy has been
shown to impair short-term memory, and the ability to concentrate
These effects can make it difficult for young people to develop a strong, positive identity,
and to learn coping skills they need
![Page 17: DRUG USE & ABUSE](https://reader031.fdocuments.net/reader031/viewer/2022031922/56815ff3550346895dcef26b/html5/thumbnails/17.jpg)
Violence & CrimeMany substances reduce inhibitions, give
users a sense of self-confidence and invulnerability, and impair judgmentThese effects can lead to violent
behaviourAlcohol has the strongest link with violent
acts – an estimated 40-50% of the violent crimes committed by inmates in Canadian
correctional facilities involved alcohol
![Page 18: DRUG USE & ABUSE](https://reader031.fdocuments.net/reader031/viewer/2022031922/56815ff3550346895dcef26b/html5/thumbnails/18.jpg)
No Quality Control for Illegal DrugsSo what’s this mean?
Although it is a serious criminal offense, new illegal drugs are constantly being developed
Many of these drugs currently available, such as crystal meth, and ecstasy are
manufactured in secret units, and basements by drug dealers, not chemists
There is no quality control over their production, and unlike real pharmaceutical
laboratories, these labs have no guidelines for cleanliness or scientific procedures
![Page 19: DRUG USE & ABUSE](https://reader031.fdocuments.net/reader031/viewer/2022031922/56815ff3550346895dcef26b/html5/thumbnails/19.jpg)
When young people in Canada drink alcohol or use another substance, they are more likely than adults to do so past the point of intoxication
This is known as BingeingWith alcohol, a female is considered bingeing
when she has 4 or more drinks per drinking occasion, while is male is considered bingeing
when he has consumed 5 or more drinks The reason for the difference is because women’s
bodies have a higher proportion of fat tissue than men’s, so their bodies absorb alcohol more quickly
Bingeing
![Page 20: DRUG USE & ABUSE](https://reader031.fdocuments.net/reader031/viewer/2022031922/56815ff3550346895dcef26b/html5/thumbnails/20.jpg)
BingeingWith other substances bingeing is not as easy
to measure, however it is still defined as using a substance past the point of
intoxicationCombining drugs such as marijuana and
alcohol, or alcohol and certain pharmaceutical drugs, can have a multiplier
effect, which means much less of each substance may be necessary to intoxicate an individual that would otherwise be the case if
either substance was used along
![Page 21: DRUG USE & ABUSE](https://reader031.fdocuments.net/reader031/viewer/2022031922/56815ff3550346895dcef26b/html5/thumbnails/21.jpg)
Bingeing is DangerousBingeing is a major cause of death and
injuries due to accidents or violence; often a result of impaired judgment or an overdose
Bingeing on alcohol can also result in fetal alcohol spectrum disorder (FASD) if the
binger is pregnantThis pattern of substance use can also
contribute to problems with parents, trouble with authorities, poor performance in school,
unwanted and unprotected sexual activity, and an increased risk of HIV infection and
other sexual transmitted infections
