• In 2013, an estimated 24.6 million persons in the United
States aged 12 years or older (9.4% OF THE US
population) were classified as having abused or been
dependent on substances subject to addiction during the

What is Drug or Substance
The Diagnostic and Statistical Manual of Mental
Disorders, Fifth Edition (DSM-5), no longer uses the
terms substance abuse and substance dependence,
rather it refers to substance use disorders,
Substance use disorders occur when the recurrent
use of alcohol and/or drugs causes clinically and
functionally significant impairment, such as health
problems, disability, and failure to meet major
responsibilities at work, school, or home. According
to the DSM-5, a diagnosis of substance use disorder
is based on evidence of impaired control, social
impairment, risky use, and pharmacological criteria.
Drug Abuse vs. Drug
Definition of Dependence Syndrome:
The Tenth Revision of the International Classification of Diseases
and Health Problems (ICD-10) defines the dependence syndrome as
being a cluster of physiological, behavioural, and cognitive
phenomena in which the use of a substance or a class of substances
takes on a much higher priority for a given individual than other
behaviours that once had greater value. A central descriptive
characteristic of the dependence syndrome is the desire (often
strong, sometimes overpowering) to take the psychoactive drugs
(which may or not have been medically prescribed), alcohol, or
tobacco. There may be evidence that return to substance use after
a period of abstinence leads to a more rapid reappearance of other
features of the syndrome than occurs with nondependent
What Causes Substance
Misuse?Biology. The genes that people are born with
account for about half of a person's risk for
addiction. Gender, ethnicity, and the presence of
other mental disorders may also influence risk for
drug use and addiction.
Environmental and social causes: A person’s
environment includes many different influences,
from family and friends to economic status and
general quality of life. Factors such as peer
pressure, physical and sexual abuse, early
exposure to drugs, stress, and parental guidance
can greatly affect a person’s likelihood of drug use
What Causes Substance
Age: Although taking drugs at any age can lead to
addiction, the earlier that drug use begins, the
more likely it will progress to addiction. This is
particularly problematic for teens. Because areas
in their brains that control decision-making,
judgment, and self-control are still developing,
teens may be especially prone to risky behaviors,
including trying drugs.
Consequences of Drug Misuse
oShort-term effects can range from changes in appetite,
wakefulness, heart rate, blood pressure, and/or mood to
heart attack, stroke, psychosis, overdose, and even death.
These health effects may occur after just one use.
oLonger-term effects can include heart or lung disease,
cancer, mental illness, HIV/AIDS, hepatitis, and others. Long-
term drug use can also lead to addiction. Drug addiction is a
brain disorder. Not everyone who uses drugs will become
addicted, but for some, drug use can change how certain
brain circuits work. These brain changes interfere with how
people experience normal pleasures in life such as food and
sex, their ability to control their stress level, their decision-
making, their ability to learn and remember, etc. These
changes make it much more difficult for someone to stop
taking the drug even when it’s having negative effects on
their life and they want to quit.

The Neurobiology of Addiction
• Above the hindbrain is the mesencephalon or
midbrain, which contains two important regions
for substance abuse:
1. Ventral Tegmental Area (VTA): which is has many
dopaminergic cell bodies that project to the limbic
system and forebrain.
2. Nucleus Accumbens: spiny neurons in this area
receive input from both the dopaminergic neurons
of the VTA and the glutamatergic neurons of the
hippocampus, amygdala, and medial prefrontal
cortex. The end result is the release of dopamine.
More to the Story…..
• Dopamine is not the only neurotransmitter
involved with substance dependence. Many
others play a role such as:
Males vs. Females
oMales start using drugs at an earlier age.
oMales abuse drugs more often and in larger
oMales are more likely to abuse alcohol and tobacco.
oClose to 12 percent of American males age 12 and
older were currently using illegal drugs, compared
with just over 7.3 percent of females in the same
age group. Multi-drug use was also more common in
males than in females.
oFemales abuse benzodiazepines more often than
o Global Burden:
In 2012, 3.3 million deaths, or 5.9 percent of all global deaths (7.6
percent for men and 4.0 percent for women), were attributable to
o Alcohol contributes to over 200 diseases and injury-related health
conditions, most notably alcohol dependence, liver cirrhosis,
cancers, and injuries.
o In 2013, 86.8 percent of people ages 18 or older reported that
they drank alcohol at some point in their lifetime; 70.7
percent reported that they drank in the past year; 56.4
percent reported that they drank in the past month.
Prevalence of Drinking: According to the 2013
National Survey on Drug Use and Health (NSDUH),
35.1 percent of 15year-olds report that they have had
at least 1 drink in their lives.17
About 8.7 million people
ages 12–20 (22.7 percent of this age group) reported
drinking alcohol in the past month (23 percent of
males and 22.5 percent of females).
Consequences of Underage Alcohol Use:Research
indicates that alcohol use during the teenage years
could interfere with normal adolescent brain
development and increase the risk of developing an
AUD. In addition, underage drinking contributes to a
range of acute consequences, including injuries, sexual
assaults, and even deaths—including those from car

• Increases the inhibitory activity mediated
by GABA-A receptors and decreases
excitatory activity mediated by glutamate
• Reinforcing effects probably due to
increased firing rate of the dopaminergic
neurons of the VTA and the dopamine
release into the nucleus accumbens.
(Benzodiazepines and Barbiturates)
Both types of drugs work on the GABA-A receptor
complex and have very strong reinforcing effects.

Potent agonist of nicotinic receptors of the
cholinergic nervous system. Promotes dopamine
synthesis by increasing tyrosine hydroxylase
expression thru activation of somatodendritic
acetylcholine receptors in the niagrostriatal and
mesolimbic dopamine pathways.
Potential for dependence surpasses all other
psychoactive substances. (most like stimulants)
Statistics for Nicotine Use in
For people aged 18 years and older:
Tobacco use remains the single largest preventable cause of
death and disease in the United States. Cigarette smoking kills
more than 480,000 Americans each year, with more than 41,000
of these deaths from exposure to secondhand smoke. In
addition, smoking-related illness in the United States costs more
than $300 billion a year, including nearly $170 billion in direct
medical care for adults and $156 billion in lost productivity.
In 2016, an estimated 15.5% (37.8 million) of U.S. adults were
current* cigarette smokers. Of these, 76.1% smoked every day.

Statistics for Nicotine Use in
For Children under age 18:
Cigarette smoking during childhood and adolescence causes
significant health problems among young people, including an
increase in the number and severity of respiratory illnesses,
decreased physical fitness and potential effects on lung growth and
Most importantly, this is when an addiction to smoking takes hold,
often lasting into and sometimes throughout adulthood. Among
adults who have ever smoked daily, 87 percent had tried their first
cigarette by the time they were 18 years of age, and 95 percent had
by age 21
In 2015, 9.3 percent of high school students reported smoking
cigarettes in the last 30 days, down 74 percent from 36.4 percent in
1997 when rates peaked after increasing throughout the first half of
What is this New Craze called
Vaping?E-cigarettes come in many shapes and sizes. Most have a
battery, a heating element, and a place to hold a liquid.
E-cigarettes produce an aerosol by heating a liquid that
usually contains nicotine—the addictive drug in regular
cigarettes, cigars, and other tobacco products—flavorings,
and other chemicals that help to make the aerosol. Users
inhale this aerosol into their lungs. Bystanders can also
breathe in this aerosol when the user exhales into the air.
E-cigarettes are known by many different names. They
are sometimes called “e-cigs,” “e-hookahs,” “mods,”
“vape pens,” “vapes,” “tank systems,” and “electronic
nicotine delivery systems (ENDS).”
Using an e-cigarette is sometimes called “vaping.”
E-cigarettes can be used to deliver marijuana and other
Types of e-cigarettes:
In the United States, youth are more likely than adults to use e-
In 2016, more than 2 million U.S. middle and high school students
used e-cigarettes in the past 30 days, including 4.3% of middle
school students and 11.3% of high school students.
“The Opioid Crisis”
Opioids encompasses both the naturally occurring
opiates such as heroin and morphine and the synthetic
and semi-synthetic preparations.
3 receptor classes in the brain for opioids:mu, delta and
Mu agonists have reinforcing properties.
Delta agonists and endogenous enkephalins seem to
produce reward, but at a lesser extent than mu agonists.
Kappa receptors appear to have an opposing effect on
reward, and are hypothesized to work with mu receptors
in keeping a balance or control of mesolimbic
Opioid Tolerance and
oWithdrawal from opioids is extremely
uncomfortable as is characterized by: watery
eyes, runny nose, yawning, sweating,
restlessness, irritability, tremor, nausea,
vomiting, diarrhea, increased blood pressure and
heart rate, chills cramps and muscle aches.
“I wasn’t taking the drugs to get high anymore, I
was taking the drugs to avoid withdrawal”.
Current Pharmacologic Treatment of
o Methadone-unusual pharmacokinetics
o Often patients still abusing other substances
o Buprenorphine (Buprenex®, Suboxone®, Subutex®)
combined with naloxone to discourage diversion. 3 times
per week, expensive
o Ofirmev™ is a new IV formulation of acetaminophen
designed for it’s synergistic effects with opioids in post
operative pain and in cancer patients. It is now being
used in emergency departments with drug seekers.
o Caldolor™ is a new formulation of ibuprofen in sterile
water for injection.
Can be injected, snorted or even smoked.
Black tar heroin is made primarily in Mexico. Names:
Negro: the Spanish word for black Piedra: the Spanish word
for stone Chiva: a Spanish word for a young goat, Nut Job ,
Muck, Frown, Slab
Historically, NYC is the city with the highest rate of heroin
Now that the governmental agencies are discouraging
healthcare professionals from prescribing opioids, the
number of heroin users is rising dramatically.
o Opioids are commonly crushed and snorted for a rush.
o Upon examination, look for constricted “pinpoint pupils”
o Hydrocodone/APAP (Norco™)-abuse at epidemic proportions.
This drug is now a “Schedule II” drug. Mixing with alcohol gives
intensified effect. Snorting may cause perforation of nasal
septum. Names: "vics", "tabs", "hydros“ or “Watsons”

is opiate naïve.
oFentanyl is not prescribed in Emergency Departments anymore.
oUsed primarily in surgery and hospice care.
oFentanyl is sometimes the substance used to lace fake Xanax.
oFentanyl is often stolen from hospice patients.
• Tylenol #3-still going strong. $5.00 for 2
tablets on high school campuses. Snorting.

Newest Approaches to Decreasing
Education of the Patient:
1. The Pain will not completely disappear.
2. Educating Patients on Hyper-analgesia
3. Referring patient to Cognitive Behavioral
5. Using ice machines after surgery
6. Using heat to alleviate pain.
Newest Approaches to Decreasing
Opioid Use (con’t)
7. A transcutaneous electrical nerve stimulation (TENS)
unit is a device that sends small electrical currents to
targeted body parts. These currents are used to relieve
pain. Some TENS units are designed for use in a hospital or
healthcare facility. Others are safe to use at home. TENS
therapy subdues hyperalgesia, which is a high sensitivity to
pain. The pain may be located anywhere on the body.
8. Trigger Point Injections using anesthetics
9. Reducing doses of pain medications and replacing with
medications in lesser controlled category.

Wednesday, October 21, 2015 “Prevalence of Marijuana Use
Among U.S. Adults Doubles Over Past
Surveys show 9.5 percent of Americans use marijuana; 30
percent of users meet criteria for a disorder.
o Long-term effects:
Marijuana also affects brain development. When marijuana users
begin using as teenagers, the drug may reduce thinking,
memory, and learning functions and affect how the brain builds
connections between the areas necessary for these functions.
Two studies involving adolescents showed an eight point
decrease in IQ for adolescents who used daily marijuana.
Cannabis derivatives are the most widely used
illicit drugs in the world.

Crack cocaine, crack or rock is a solid form of cocaine
which is smoked. It is a freebase form of cocaine that
can be made using baking soda (sodium bicarbonate)
or sodium hydroxide, in a process to convert cocaine
hydrochloride (powder cocaine) into
methylbenzoylecgonine (freebase cocaine).
Crack cocaine is used by the African American
community at a very high rate.

Stimulates release of dopamine from nerve terminals via
dopamine transporter-dopamine is released independently
of neuronal excitation-this contrasts cocaine which blocks
reuptake in the synapse only.
New pseudoephedrine legislation has helped.

This has driven the price upward.
Fewer children able to afford.
Damage to dopaminergic neurons is severe-

chemical transmission is still affected.
Ecstasy….”The Love Drug”
Street names: XTC, E, Adam, cloud 9, herbal bliss
Most worrisome: youth do not perceive this drug
Club drug, used at rave parties
Classified as a psycho-stimulant, but is also a
hallucinogen in very high doses.
New pharmacological class: entactogens-means
“entering into contact with yourself”
Abuse of this drug is spreading across the world. In
Asian countries, more ecstasy is consumed than
heroin and cocaine combined. In Australia, 90% of
all users inject the drug. In the US, the drug is
primarily ingested or smoke, but maybe snorted or
Most effects are serotonergic, but dopamine and
NE are also released.
Ecstasy is neurotoxic
Neurotoxicity is dose and frequency related-It is
Severe reductions in serotonin and its
transporters and neurons.
Impairment in regulation of body temperature
Impairments in memory, decision-making, and

oDrug Class: Hallucinogen, dissociative anesthetic,
oLiquid form used to dip “joints” into=Angel Dust
oMedical and Recreational Uses: Formerly used as a
surgical anesthetic, however, there is no current
legitimate medical use in humans. Used as a
veterinary anesthetic or tranquilizer. Recreationally
used as a psychedelic and hallucinogen.
Used to be purchased in smoke shops legally.
Now illegal, but flourishing on the streets.
Lasting effects including Psychotic symptoms
Extremely addictive (psychologically)
Causes extreme violence in some people.
o The term “bath salts” refers to an emerging family of drugs
containing one or more synthetic chemicals related to cathinone,
an amphetamine-like stimulant found naturally in the khat plant.
o Reports of severe intoxication and dangerous health effects
associated with use of bath salts have made these drugs a
serious and growing public health and safety issue. The
synthetic cathinones in bath salts can produce euphoria and
increased sociability and sex drive, but some users experience
paranoia, agitation, and hallucinatory delirium; some even
display psychotic and violent behavior, and deaths have been
reported in several instances.
Street names: special K, Kit kat, Cat Valium, K,
Purple, jet, etc…..
Used in veterinary medicine and in conscious

Effects are subjective-some feel euphoric and
happy, and some have a “bad trip” referred to as a
Dissociative (like LSD)-can be injected, inhaled,
mixed with ecstasy and smoked.
• Mitragyna speciosa, commonly known as kratom, grows naturally in
Thailand, Malaysia, Indonesia and Papua New Guinea.
• Serious concerns exist regarding the toxicity of kratom in multiple
organ systems. Consumption of kratom can lead to a number of
health impacts including, respiratory depression, vomiting,
nervousness, weight loss and constipation.
• Kratom has been indicated to have both narcotic and stimulant-like
effects and withdrawal symptoms may include hostility, aggression,
excessive tearing, aching of muscles and bones and jerky limb
• This drug has been sold in California as a natural botanical cure for
• The FDA and CA Dept. of Public health have placed an embargo on
its import and sales.
What is Krokodil
Desomorphine, known by thestreet name krokodil, is an
opioid derivative of codeine Like heroin and other opioids it
has a sedative and analgesic effect, is highly addictive, and
Those who inject these caustic agents into their veins can
develop extreme skin ulcerations, infections, and gangrene- a
discolored (green, black) scale-like skin that resembles a
crocodile, hence the street name “krokodil”.
The drug has been noted to be fast-acting and eight to ten
times more potent than morphine. However, the half-life is
short, and euphoric effects may last less than two hours. Due
to the short “high”, many users find themselves in a rapid
repetition of drug synthesis to avoid withdrawal symptoms
that are typical of heroin.
Side Effects of Krokodil
Reported Blood vessel damage
Open ulcers, gangrene, phlebitis
Skin and soft tissue infections
Side Effects of Krokadil (con’t)
• Rotting gums/tooth loss
• Bone infections (osteomyelitis)
• Speech and motor skills impairment
• Memory loss and impaired concentration
• Liver and kidney damage
Miscellaneous Drugs of
•Ibuprofen in albuterol metered dose inhalers. (HFA
won’t work!)Albuterol helped open the airways.
•Seroquel crushed and snorted “S, Quel”
•Wellbutrin crushed and snorted for a rush
•Dextromethorphan “DXM, Robo-tripping, skittling,
triple C”- dissociative effects in high doses. Abused by
teens. Available in powder form on the internet.
