How to Assess & Provide Appropriate Care
Definitions Drugs, Effects & Consequences Statistics Professional Responsibilities Treatment Options
Key Terms Dependence: indicates an altered
physiologic state caused by repeated administration of a drug the cessation of which results in a specific syndrome
Terms continued Abuse: use of any drug, usually by self
administration, in a manner that deviates from approved social or medical patterns
Misuse: usually applied to prescribed medications that are not used properly
Addiction The repeated and increasing use of a
substance or behavior, when deprived, causes symptoms of distress, and an irresistible urge to use the agent or engage in the behavior again despite consequences (physical, social, legal).
Withdrawal A substance of the specific syndrome that
occurs after stopping or reducing the amount of substance that has been used regularly over a prolonged period characterized by physiological and psychological signs and symptoms. Also called abstinence syndrome or
discontinuation syndrome
Tolerance A physiological phenomenon which
occurs after repeated consumption of a drug producing decreased effect despite increasingly larger doses to achieve the first affect. Behavioral tolerance reflects the ability to
perform tasks despite the effects of the drugs
Cross-tolerance The ability of one drug to be substituted
for another each usually producing the same physiological and psychological effects Benzodiazepines and barbiturates
Neuro adaptation: Neurochemical changes in the body that result from the repeated administration of a drug which accounts for the phenomenon of tolerance
Codependence Friends or family members affected by
the behavior of a substance abuser, facilitating the abusers addictive behavior, requires the unwillingness of a family member to accept addiction as a medical psychiatric disorder, and denial that a person is abusing the substance. Enabler
Denial A primitive defense mechanism
characterized by an unwillingness to accept ego-dystonic obvious circumstances.
Epidemiology 22 million people older than the age of 12
were classified as having a substance related disorder 10% of the total US population
(National Institute of Drug Abuse 2012)
21 million (9.3%) people are diagnosed with diabetes in the United States (CDC 2012)
Who are the 22,000,000? 15 million were dependent on or abuse
alcohol 669,000 people were dependent on or
abused heroin 4.3 million abused marijuana 1 million abused cocaine 2 million were classified as dependent on
or abused pain relievers
22 million Those who use any substance younger than
15 years of age for more likely to become addicted than those who started at a later age
Of Adults 21 and older who first tried alcohol at age 14 or younger 15% were classified as alcoholics 3% who first used alcohol at age 21
Men > Women| Whites > Blacks| Higher Edu. > Lesser Edu.| Unemployed > employed
Etiology It depends on the individual and the
circumstances It requires drug availability & social
acceptability Likelihood is increased with peer pressure and
initial experimentation experience Addiction determinant: is influenced by
personality, individual biology, actions of the drug
Brain Disease From voluntary to compulsive Classic theories: substance abuse is a
masturbatory equivalent (heroin users describes the initial rushes similar to a prolonged sexual orgasm)
Defense against anxious impulses or a manifestation of oral regression
Disturbed Ego function: inability to deal with reality (self-medication).
Factors influencing addiction Behavior maintained by
its consequences Genetic factors: twin
studies suggested a component for alcoholism
Neurochemical factors: Receptors and Receptor Systems
Pathways and neurotransmitters comprise the brain reward circuitry Dopamine, GABA,
Opioids
Brain Reward Pathway
Other Neurotransmitters
Insightful Diagnosis and Treatment
Diagnostic ClassificationSUBSTANCE USE DISORDER: a maladaptive
pattern of use leading to significant impairment or distress as manifested by 2 or more of the following occurring within a 12 month period
Failure to fulfill major role obligations
Recurrent use and situations in which physical hazard may occur i.e. driving
Continued use despite having persistent or recurrent social or interpersonal problems exacerbated by effects of the substance
Tolerance developed Withdrawal Increasing use Persistent desire or
unsuccessful efforts to cut down
Giving up important activities for the substance use
Continued use despite knowledge of persistent and recurrent physiological problems
Craving to use
Substance Withdrawal A substance
specific syndrome resulting from the abrupt cessation of heavy or prolonged use of a substance
The development of a syndrome due to the cessation or reduction in substance use that has been heavy
Syndrome that causes clinically significant distress or impairment
Symptoms are not due to a general medical condition or another mental disorder
Corollary & Comorbid Antisocial
Personality Disorder
Mood Disorders Anxiety Disorders Suicidality Delirium Psychosis Dementia
Sleep Disorders Sexual Dysfunction Amnestic Disorder Intoxication Flashbacks Cognitive
impairment Encephalopathies
Cannabinoids Hashish, Marijuana How Consumed: swallowed, smoked Effects: euphoria, slowed thinking and
reaction time, confusion, impaired balance and coordination
Consequences: cough, frequent respiratory infections, impaired memory and learning, increased heart rate, anxiety, panic attacks
Depressants Barbiturates, Benzodiazepines, GHB, Rohypnol,
Quaalude How Consumed: swallowed, injected Effects: reduced anxiety, feeling of well-being,
lowered inhibitions, slowed pulse and breathing, lowered blood pressure, poor concentration
Consequences: fatigue, confusion, impaired coordination, memory, judgment, respiratory depression and arrest, death
Dissociative Anesthetics
Ketamine, PCP How Consumed: Injected, swallowed, smoked,
snorted Effects: increased heart rate and blood pressure,
impaired motor function, delirium, panic, aggression
Consequences: memory loss, numbness, nausea/vomiting, depression
Hallucinogens LSD, Mescaline, Mushrooms How Consumed: swallowed, smoked Effects: increased body temperature, heart rate,
blood pressure, loss of appetite, sleeplessness, numbness, weakness, tremors, altered states of perception and feeling, nausea
Consequences: persisting perception disorder (flashbacks)
Opiods Codeine, heroin, morphine, opium,
Oxycodone, Hydrocodone How Consumed: injected, swallowed,
smoked, snorted Effects: pain relief, euphoria, drowsiness Consequences: nausea, constipation,
confusion, sedation, respiratory depression and arrest, unconsciousness, coma, death
Stimulants Amphetamine, cocaine, MDMA,
methamphetamine, nicotine, Ritalin How Consumed: injected, smoked, snorted,
swallowed Effects: increased heart rate, blood pressure,
metabolism, feelings of exhilaration, energy, increased mental alertness
Consequences: rapid or irregular heart beat, reduced appetite, weight loss, heart failure, nervousness, insomnia
Assessment Open-ended questions
Motivational Interviewing BATHE technique
Obtain releases for/ from all other providers
Maintain active communication with providers
Observations: MSE and Physical exam findings
R.U.L.E. Resist the righting reflex
Psychological reactivity & Therapeutic Paradox Understand your patient’s motivation
Why would they want to? Listen to your patient
Equal parts of listening & informing Empower your patient
Help in contemplating the how and why
How to refer for evaluation It sounds like you may benefit from
talking to someone Provide 2-3 referrals Provide the patient with reassurance that
you are referring to a resource you trust
Reflective Listening
Validate & Affirm

Craving mediated by Expectancies For immediate effect
Rationalization,Denial, and apparently irrelevantdecisions
Lifestyle imbalance(Shoulds> wants) Desire for
indulgence or immediate gratification (I owe myself)
Precursors to High Risk Situations
High Risk Situation
Coping Response
No Coping Response
Increased Self-Efficacy
Decreased Self-Efficacy
Decreased probability of relapse
Lapse
Abstinence Violation Effect
Relapse
Cognitive Behavior Model of the Relapse Process
HIGH RATES OF RELAPSE:
Negative Emotional State (35%)
Interpersonal Conflict (16%)
Social Pressure (20%)

Goals of Drug Treatment:Keeping an Eye on the Target
Reduced Criminal Behavior
Drug addiction is a brain disease that affects behavior.
Brain changes in addiction help explain continued drug abuse and relapse.
Relapse Rates for Drug Addiction are Similar to Other Chronic Medical

Drug Abuse Treatment Can Work
• No single treatment is appropriate for all individuals.
• Treatment needs to be readily available.
• Treatment must attend to multiple needs of the individual, not just drug use.
• Multiple courses of treatment may be required for success.
• Remaining in treatment for an adequate period of time is critical for treatment effectiveness.
