9 Drugs of abuse screen

10 Objectives What does a drug screen indicate? What are common drugs abused? What are the effects of drugs on the heart and brain? How does it effect treatment?

11 North Dakota: Leader of the Pack North Dakota Ranks #1 in Binge Drinking

12 Teen Alcohol Statistics 95% of the alcohol consumed by youth under the age of 21 in the U.S. is in the form of binge drinks. Binge drinking is associated with many health problems, including Unintentional injuries (e.g., car crashes, falls, burns, drowning) Intentional injuries (e.g., firearm injuries, sexual assault, domestic violence) Alcohol poisoning Sexually transmitted diseases Unintended pregnancy Children born with Fetal Alcohol Spectrum Disorders High blood pressure, stroke, and other cardiovascular diseases Liver disease Neurological damage Sexual dysfunction, and Poor control of diabetes.

13 Drug Use - Study In 2009, the safety agency issued the National Roadside Survey of Drug and Alcohol Use by Drivers: Alcohol was the most likely intoxicant 8.6 percent of the total tested had used marijuana 3.9 percent had used cocaine 1.3 percent tested positive for methamphetamine

14 Drug Use Two studies (44,000 collisions): One out of four drivers involved in crashes had marijuana, cocaine, amphetamines, or some combination of those drugs in their system Approximately 14 percent of all drivers on the road have an illegal drug in their system

15 Marijuana

16 Marijuana Raises the heart rate % 4.8 fold increase in the risk of AMI in the first hour after smoking. This risk increases as other risk factors increase. Effects thinking and memory Stunts brain development Causes a decrease in IQ in subjects using through teens and twenties. Increased respiratory illness

17 Marijuana Linked to increased mental illness such as: Depression Anxiety Suicide Psychosis Impairs judgment and contributes to increased risk of injury or death. Specific link to lung cancer not well established at this point

18 Marijuana No Specific antidote Symptomatic Treatment

19 Narcotics One of the oldest pharmacological substances Histamine releasing properties Produce bradycardia and hypotension by increasing parasympathetic and decreasing sympathetic response Strong respiratory depressant Can produce coma Infection from injection

20 Narcotic Treatment Symptomatic treatment Antidote is Naloxone Half life can be shorter than the narcotic

21 Cocaine Strong central nervous system stimulant that increases levels of dopamine Changes the short and long term reward system in the brain

22 Cocaine Effects Constricts blood vessels Increases heart rate Increases blood pressure Increases body temperature Increased risk of AMI and Stroke Increased risk of sudden cardiac arrest.

23 Cocaine Treatment No specific antidote Symptomatic Treatment

24 Synthetic Drugs Fake Substances... Real Dangers K2, Spice, Bath Salts, Smiles...

25 Synthetic Drugs What are they? Synthetic marijuana (often known as K2 or Spice ) and bath salts products are often sold in legal retail outlets as herbal incense and plant food, respectively, and labeled not for human consumption to mask their intended purpose and avoid FDA regulatory oversight of the manufacturing process.

26 Synthetic Drugs How frequently is synthetic marijuana used? Use of synthetic marijuana is alarmingly high o 11.4 percent of 12 th graders used Spice or K2 in the past year *second most commonly used illicit drug among seniors

27 Synthetic Drugs What are they? Bath salts contain manmade chemicals related to amphetamines, also known as substituted cathinones. Cathinone derivatives are claimed to have effects similar to cocaine, amphetamine or MDMA (ecstasy).

28 Smiles (not the good kind) Designer Drug 2C- I The drug, a hallucinogen, has been linked to two deaths in Grand Forks, North Dakota. Though little is known about this drug's dangers. Smile s effects: combination of MDMA (ecstasy) and LSD speedy charge along with intense visual and auditory hallucinations

29 Synthetic Treatment No specific antidote Symptomatic Treatment

30 Methamphetamine % of population or 1.2 million report using 103,000 ED visits directly related in th most commonly mentioned abused drug by ED patients nationally behind Marijuana, Cocaine, and Heroin

31 Methamphetamine effects Increased attention and decreased fatigue Increased activity and wakefulness Decreased appetite Euphoria and rush Rapid/irregular heartbeat Vasoconstriction Hypertension Hyperthermia

32 Methamphetamine chronic effects Anxiety Confusion Insomnia Mood disturbances Violent behavior Psychosis Hallucinations visual and auditory Paranoia

33 Effects of Meth on the Brain Meth rewires the brain. Prolonged use not only modifies behavior, but literally changes the brain in fundamental and long-lasting ways. Even while recovery may be possible, the brain won t be the same.

34 Effects of Meth on the Brain PET Scan of a meth user and a control subject

35 Face lift courtesy of meth 2 months later 1 year, 5 months later 2 years, 5 months later 1 year, 5 months later

36 Effects of Meth Dental Decay Skin Lesions Psychosis

37 Unnecessary Deaths Teenage male collapses from unknown causes. Dies one day later. Dx: Sudden cardiac death secondary to bad meth.

38 Unnecessary Deaths 17-year-old male and 23-year-old female with AMI. Both heavy meth users. 19-year-old presents with blood pressure of 290/160. Dies from a stroke after meth injection.

39 Methamphetamine Treatment No specific antidote Symptomatic Treatment

40 Drugs of Abuse Screen Screening test not a definitive test Must be metabolized and excreted to be present Metabolites present for variable periods Most 2-3 days Does not test for all abused substances For example fentanyl a synthetic opiate does not trigger positive for opiates.

41 Pearls No specific antidote for most abused drugs except for Narcotics and Benzodiazepines.

42 Pearls Flumazenil should not be given to benzodiazepine abusers and should only be used for iatrogenic overdose.

43 Pearls Naloxone reverses narcotics Reversing narcotic overdose usually results in bad behavior Half life is shorter than many abused narcotics and repeated dosing may be needed.

44 Pearls Gastric lavage has almost no utility Treatment is generally symptomatic Drug screen utility is to add evidence to clinical findings

45 Case Study

46 Case Study Arrives intubated with no neurologic response. In Rhabdomyolysis and has hyperkalemia.

47 Case Study

48 Case Study

49 Case Study Hypothermia protocol for 24 hours Treated for Rhabdo and hyperklemia Rewarmed No neurologic recovery MRI shows diffuse edema and herniation Brain death testing protocol Support pulled and patient died Diagnosis: Death due to anoxic encephalopathy secondary to methamphetamine overdose
