Transcript Psychoactive Drugs

Underline the answers to the following
questions while reading the article.
1. Is there any way to predict the effects felt
from using marijuana?
2. What can substances sold as marijuana
often be mixed with?
3. What are some examples of how people who
smoke marijuana regularly can have
changes in personality?

Marijuana ranks first, followed in order by cocaine,
hallucinogens, and heroin. Alcohol remains by far
the most popular drug among college students.
However, the vast majority of college students
(80%) report no drug use in the previous month.

B. Nicotine. Valium is also addictive, LSD and
marijuana less so. Nicotine is believed to be
the most highly addictive psychoactive drug.

A. This figure is even lower for drugs that are
difficult to obtain or manufacture. Street
drugs may be sold in unsafe dosages and are
typically mixed or cut with cheaper and often
more hazardous substances.
Changes in Brain chemistry occur dependent on
the method of administration
 Oral Ingestion
 Injection (can be into the intramuscular or intravenous)
 Smoke
 Inhalation
 Absorption
 The quicker the drug reaches the brain the
more likely the user is to become dependent.
 Once a drug reaches the brain, it acts on one or
more neurotransmitters, either increasing or
decreasing their concentration and actions.



Addiction - continued involvement with a
substance despite negative consequences
Dependence – when the person feels they
need the drug
◦ can be physical and/or psychological



Tolerance – when the person needs more
and more to get the same effect
Withdrawal – a series of symptoms that occur
when an addict stops using a drug.
Relapse – the tendency to return to addictive
behavior after a period of abstinence.



Euphoria – “high”
Synesthesia – an effect where sensory
messages are incorrectly assigned (hear a
taste, smell a sound)
Flashbacks – perceptual distortions and
bizarre thoughts that occur after the drug
has been eliminated from the body


Drugs can be separated into Types and
Categories
Types of Drugs:
◦ Prescription Drugs
◦ Over-the-Counter (OTC) Drugs
◦ Recreational Drugs
 alcohol, tobacco, caffeine
◦ Illicit Drugs
 Illegal
 Most are psychoactive – changes brain
chemistry

Most widely used illegal drug in the

Marijuana is derived from the
Cannabis Sativa plant
Other names include:
◦ Pot, grass, sinsemilla, blunts, mota, yerba,
grifa ,Aunt Mary, Boom, Chronic (marijuana
alone or marijuana with crack), Dope ganja,
Gangster, Hash, Herb, Kif, Mary Jane, Pot,
Reefer, Sinsemilla, Skunk, Weed


THC (tetrahydrocannabinal) is the main active
ingredient in the marijuana plant
◦ THC is the principal mind-altering ingredient
◦ THC travels through the bloodstream to all cells in the
body and is stored in the fat cells of the body
especially around the lungs, the brain, and the
reproductive organs
◦ The strength of marijuana has increased to 10 times
the amount of THC since the 1960’s.

There are over 400 chemicals in marijuana
that break down into over 2,000 chemicals


Marijuana can be smoked ,
inhaled or ingested
Smoking provides a direct route
to the brain and effects can be
felt in minutes
◦ Can reach their peak in 10 to 30
minutes but can linger for 2 to 3
hours

THC is fat -soluble
◦ This means it can be stored in the
body for long periods of time
◦ Marijuana can be measured in the
body up to 30 days after use

Marijuana cigarettes contain more carcinogens
than tobacco cigarettes
◦ Marijuana contains 50 – 100% more tar than cigarettes
◦ 1 marijuana cigarette = tar of 14 tobacco cigarettes



Marijuana also contains carbon monoxide which
diminishes oxygen in the blood.
People who smoke both marijuana and tobacco
dramatically increase their risk of lung diseases.
Exposure to second-hand smoke on a regular
basis can be stored in the fat cells and can be
tested positive as a user.
In low doses the effects are strongly influenced by
the user’s expectations and past experiences
▶ Changes include:
▶
o Euphoria – “high”
o Mood changes
o Impaired short-term memory (forgetfulness)

substances, the most common being sugars and
local anesthetics.
 This is done to stretch the amount of the product
and increase profits for dealers.



“crash”



Crack is highly addictive
It is common to be addicted to
crack after only one use.
◦ This is because crack produces a short
but intense high. Smoking it provides
a more direct route to the brain.
◦ The high is followed by a severe
“crash”.
◦ The high is so short-lived and the
“crash” is so low the user takes another
hit.

Prescription drug abuse is:
◦ Taking a prescription medication that
is not prescribed for you.
◦ Taking it for reasons or in dosages
other than as prescribed.
 Abuse of prescription drugs can
produce serious health effects,
including addiction, and can be life
threatening.

Opioids:
◦ Hydrocodone (Vicodin®), Oxycodone (OxyContin®),
Propoxyphene (Darvon®), Hydromorphone
(Dilaudid®), Meperidine (Demerol®), and
Diphenoxylate (Lomotil®)



Stimulants:
◦ Dextroamphetamine (Dexedrine®), Methylphenidate

A 2006 study reported that overdoses from
opioid painkillers kill more people than
overdoses from either cocaine or heroin.
The National Institutes of Health (NIH)
estimates that close to 20 percent of people
(48 million) over the age of 12 in the U.S. have
used prescription drugs for non-medical
purposes.
More than 200,000 visits to emergency rooms
around the country each year are because of
prescription drug abuse.

What are anabolic steroids?
◦ Anabolic steroids are synthetic drugs derived from
hormones, primarily testosterone.
◦ Anabolic steroids are considered ergogenic drugs
which are drugs used to enhance athletic
performance.
◦ Anabolic steroids are designed to diminish the
androgenic effects of testosterone while amplifying
the anabolic effects.
 Increased anabolic effects produce muscle growth.
 Decreased androgenic effects produce diminished
expression of sexual characteristics.



Anabolic steroids mimic the
effects of the male sexual
hormone, testosterone.
Anabolic steroids work only in
conjunction with physical
training and a high-protein,
high-calorie diet.
Use of steroids can produce a
significant increase in lean
muscle mass, strength and
muscle endurance.



Weight lifters and body builders to produce
gains for competitions
Specific athletes requiring strength such as
football players, throwing events in track and
field (shot-put, discus, hammer throw) and
baseball players.
Specific athletes requiring speed such as
swimmers and running events in track and
field (sprinters).
People who just want to get larger muscles
for self-gratification.

Increase in aggression and temper “Roid Rage”
*Many of these effects are irreversible.
Because of the decrease androgenic effects of
testosterone in Anabolic steroids, several sexual side
effects are possible:


◦
Shrinking of the testicles
Reduced sperm count
Impotence

◦ Changes in menstruation
◦ Enlargement of the
clitoris
◦ Deepened voice
