    • Chronic Pain and Addiction April 10-12, 2012 Walt Disney World Swan ResortDr. Barbara KrantzMedical Director/Corporate Director of ResearchFellow of the American Society of Addiction MedicineDiplomat of the American Board of Addiction Medicine
    • Accepted Learning Objectives:1.  Overview on Drug Abuse in US, focusing on national Statistics on nonmedical psychotherapeutics including older adult trends with chronic pain diagnosis.2.  Describe the effects and consequences of prescription pain abuse as it progresses over time.3.  Advocate the importance of continuing education on addiction for pain management providers.
    • What is Prescription Drug Abuse?•  Prescription drug abuse is the intentional use of a medication without a prescription; or in a way other than as prescribed; or for the experience or feeling its causes.•  The three classes of prescription drugs that are most commonly abused are: –  Opioids, which are most often prescribed to treat pain –  Central nervous system (CNS) depressants, which are used to treat anxiety and sleep disorders –  Stimulants, which are prescribed to treat the sleep disorder narcolepsy and attention-deficit hyperactivity disorder (ADHD).

    • Media Attention
    • Prescription Drug AbuseWhat is driving the high prevalence? - misperceptions about their safety - increasing environmental availability - varied motivations for their abuse - consumer culture amenable to “quick fix”Among those who abuse prescription drugs, high rates of otherbehaviors, including abuse of other drugs and alcohol, have alsobeen reported.
    • Highlights - Global•  Globally, it is estimated that 13.5 million people take opioids, including 9.2 million who use heroin. WHO, 2010•  In many countries (notably those from Europe), the majority of heavy drug users seeking treatment are primarily addicted to opiates UNDCP, 2009•  Worldwide abuse of prescription drugs will soon exceed illicit drug use, warned a United Nations panel charged with monitoring global patterns of drug abuse.•  In its 2006 report, the International Narcotics Control Board (INCB), based in Vienna, Austria, noted that medications containing narcotic or psychotropic drugs are becoming the drugs of choice for many abusers, and that drug traffickers are responding to the demand through increased diversion and the production of counterfeit drugs.•  The problem is particularly acute in the United States, where cannabis is the only illicit drug that is more widely abused than prescription drugs, including analgesics, stimulants, sedatives, and tranquilizers, according to the INCB. Between 1992 and 2003, the number of US individuals abusing prescription drugs increased from 7.8 million to 15.1 million.
    • National Key Points•  The non-medical use or abuse of prescription drugs is a serious and growing public health problem in this country. It is the nation’s fastest growing drug problem.•  Approximately 48 million people ages 12 and older have used prescription drugs for non-medical reasons in their lifetime.•  The percentage of unintentional drug poisoning deaths involving opioid analgesics has been increasing since 1999, while those involving cocaine and heroin have been steadily decreasing.•  Opioid analgesics (i.e. hydrocodone, oxycodone, and methadone) are more likely than cocaine or heroin to be the cause of unintentional drug poisoning deaths in U.S.
    • National Key Points From the CDC (2010) Report2010 CDC Report:•  It stated that there were 27,658 annual fatal unintentional drug poisonings as of 2008.•  Drug overdose deaths are second only to car crashes for unintentional injury deaths.•  Overdose is the number one injury-related killer among adults aged 35-54.•  Rates of unintentional drug overdose deaths have increased 5-fold since 1990.
    • National Key Points•  In 2000, retail pharmacies dispensed 174 million prescriptions for opiods. By 2009, 257 million were dispensed, an increase of 48%.•  Opiate overdoses once almost always due to heroin, are now increasingly due to abuse of prescription painkillers.•  Parents, patients, healthcare providers and manufacturers play a critical role in preventing prescription drug abuse.•  The potent medications science has developed have great potential for relieving suffering as well as great potential for abuse.•  Increasing need to minimize abuse of prescription drugs and ensure access for their legitimate use.
    • National Key Points•  1/3 of people aged 12 and over who used drugs for the first time in 2009 began by using a prescription drug non-medically.•  70% of people who abused prescription pain relievers got them from friends or relatives, while approximately 5% received them from a drug dealer or the internet.•  In our military, illicit drug use increased from 5% to 12% among active duty service members over a 3 year period from 2005 – 2008, primarily attributed to prescription drug abuse.•  From 1997 to 2007, the milligram per person use of prescription opioids in the United States increased from 74 mg to 369 mg, an increase of 402%!
    • National Prevalence of Prescription Drug Abuse•  In 2009, 7 million Americans reported current (past month) nonmedical use of prescription drugs – more that the number using cocaine, heroin, hallucinogens, and inhalants combined.•  National surveys show that the number of new abusers of several classes of prescription drugs increased markedly in the United States in the 1990’s.•  Continuing at high rates during the past decade, abuse of prescription drugs now ranks second (after marijuana) among illicit drug users.•  Perhaps even more disturbing, approximately 2.2 million Americans used pain relievers non-medically for the first time in 2009 (initiates of marijuana use were 2.4 million).
    • Indicators of Prescription Drug Abuse Epidemic in this CountryTreatment admissions for opiates other than heroin rose from 19,870 in 1998 to 111,251 in 2008, over a 450% increase.The number of fatal poisonings involving prescription opioid analgesics more than tripled from through 2006, outnumbering total deaths involving heroin and cocaine.The Drug Abuse Warning Network (DAWN), which monitors emergency department(ED) visits in selected areas across the Nation, estimates that in 2008, roughly 305,000ED visits involved nonmedical use of Prescription pain relievers; 19,000 involved CNSstimulants; and 325,000 involved CNS depressants (anxyiolytics, sedatives, andhypnotics). Over half involved more than one drug. These numbers have more thandoubled for pain relievers, and nearly doubled for stimulants, and CNS depressants since 2004.ED visits related to zolpidem (Ambien) – one of the most popular prescribed non-Benzodiazepine hypnotics in the United States – also more than doubled during thisperiod, from about 13,000 in 2004 to about 28,000 in 2008.
    • National Prevalence of Prescription Drug AbuseMore law enforcement agencies are reportingthat pharmaceutical diversion and abuse posethe greatest drug threat to their areas, in partbecause of increases in associated crime andgang involvement, which put additional strainon agency budgets and assets.
    • Percentage of State and Local Law EnforcementAgencies Reporting CPD’s as their Greatest Drug Threat 2005-2009
    • Percentage of State and Local Law Enforcement Agencies Reporting Street Gang Involvement in Pharmaceutical Distribution and an Association Between Pharmaceutical Diversion and Crime, 2008-2009 2008 2009Street Gang Involvement 44.2% 48.0%Property Crime 6.0% 8.4%Violent Crime 3.5% 4.8%National Drug Threat Survey
    • National Key ElementsAmong adolescents, prescription and over-the-countermedications account for most of the frequently abused drugsby high school seniors (including tobacco and alcohol).- Nearly 1 in 12 high school senior reported non-medical use of Vicodin; 1 in 20 reported abuse of Oxycontin.- When asked how prescription pain relievers were obtained for non-medical use, 59% of 12 graders said they were given to them by a friend or a relative. The number obtaining them over the internet was negligible.
    • Older Adults
    • Changing Substance Abuse Patterns Among Older Admissions•  Older substance abuse treatment admissions (aged 50 or older) increased from 6.6% of all admissions 12 years of age or older in 1992 to 12.2 % in 2008.•  Between 1992 and 2008, the proportion of older admissions that reported primary alcohol abuse decreased from 84.6% to 59.9%,•  The proportion of older admissions that reported multiple substances of abuse nearly tripled, increasing from 13.7% in 1992 to 39.7% in 2008.•  In 2008, older admissions who initiated use of their primary substance of abuse within the past 5 years were more likely than those in 1992 to have reported prescription pain relievers as their primary substance (25.8% vs. 5.4%).

    • Health Effects of the Prescription Drug Abuse•  The abuse of opiods can produce drowsiness, constipation and depending on the amount taken, can cause respiratory depression and ultimately death. Repeated use can lead to physical dependence and addiction.•  The abuse of the central nervous system depressants can result in seizures, respiratory depression and decreased heart rate.•  Stimulant abuse can lead to high body temperature, irregular heart rate, cardiovascular system failure and seizures. Taken repeatedly, it can cause paranoia and anxiety.
    • Effects on the Brain and BodyOpioids act on the brain and body at attaching to specific cell surfaceproteins called opioid receptors, which are found in the brain, spinal cord,gastrointestinal tract and other organs. When these drugs attach to certainopioid receptors, they alleviate the perception of pain.These drugs can induce euphoria by indirectly boosting dopamine levels inthe brain regions that influence our perception of pleasure.Abusers may snort or inject the drug amplifying its euphoric affects andincreasing medical risk such as respiratory arrest, coma and addiction.
    • Effects on the Brain and BodyStimulants elicit a gradual and sustained increase in dopamine, which produces theexpected therapeutic effects seen in many patients with ADHD, calming andfocusing.Methylphenidate is similar to cocaine, in that it binds to similar molecular targets inThe brain, thereby increasing dopamine in reward circuits.When administered intravenously, both drugs cause a rapid and large increase indopamine, which is experienced as a rush.For those who abuse stimulants, the range of adverse health consequencesInclude hyperthermia, seizures and cardiovascular complications.
    • Effects on the Brain and BodyCNS depressants, typically prescribed for the treatment of anxiety, sleep disorders,acute stress reactions, and muscle spasms, include drugs such as benzodiazepines(e.g., valium, xanax) and barbiturates (e.g., Phenobarbital) – which are sometimesprescribed for seizure disorders. Most CNS depressants act on the brain by affectingthe neurotransmitter gamma – Aminobutyric acid (GABA), which works by decreasingbrain activity. CNS depressants enhance GABA’s effects and thereby produces adrowsy or calming effect to help those suffering From anxiety or sleep disorders. Thesedrugs are also particularly dangerous when mixed with other medications or alcohol;overdose can suppress respiration and lead to death. The newer non-benzodiazepinesleep medications, such as zolpidem (Ambien), exzopicione (Lunesta), and zalepron(Sonata), have a different chemical structure, but act on some of the same brainreceptors as benzodiazepines and so many share some of the risks - they arethought, however, to have fewer side effects and less dependence potential.
