1 Chapter 17: Pharmacology, Drugs and Sports

2 Pharmacology is the branch of science that deals with the action of drugs on the biological systems
Specifically those that are used in medicine for diagnostic and therapeutic purposes Used to achieve definite outcomes that improve quality of life Various drugs and other substances are being used widely for performance enhancement or mood alteration

3 What is a drug? Chemical agent used in prevention, treatment, & diagnosis of disease Ancient practice dating back to the Egyptians Many are derived from natural sources Drugs which have, in the past, come from nature are now produced synthetically

4 Pharmacokinetics Method by which drugs are absorbed, distributed, metabolized and eliminated from the body Pharmacodynamics is the actions or effects of drugs on the body

5 Administration of Drugs
Must first enter the system and reach receptor tissue to be effective Drug vehicles Therapeutically inactive substance used to transport drug (solid or liquid) Internal administration Inhalation (medication through respiratory tract) Intradermal (into the skin) Intramuscular (medication directly into muscle) Intranasal Intraspinal (medication injected into the spine)

6 External Administration
Intravenous (into a vein) Oral (most common form) Rectal (limited due to dosage regulation) Sublingual/buccal (dissolvable agents placed under tongue Intravaginal (placing drug device inside vagina) External Administration Inunctions (oil based medication rubbed into skin) Ointments (long lasting topical medication) Pastes (ointments with nonfat base) Plasters (thick ointment, counterirritant for pain & inflammation relief, increasing circulation) Transdermal patches (patch with slow release mechanism) Solutions (administered externally)

7 Absorption of Drugs Drug must dissolve before absorption
Rate and extent determined by chemical characteristics of drug, dosage, and gastric emptying Bioavailability How completely a drug is absorbed by the system Dependent on characteristics not dosage (Absorption rate dependent on dosage form)

8 Distribution Metabolism
Once absorbed, drug is transported through blood to target tissue Volume of distribution: volume of fluid/plasma in which drug is dissolved and indicates extent of distribution of that drug Efficacy: capability of producing therapeutic effect Potency: dose of the drug required to produce a desired therapeutic effect Metabolism Biotransformation of drug to water soluble compounds that can be excreted Most takes place in liver, rest in blood and kidneys Liver detoxifies active agents Metabolites may be toxic

9 Excretion Excretion of drug or its metabolites is controlled by kidneys Filtered through kidneys and usually excreted in the urine (some is reabsorbed) May also be excreted in saliva, sweat and feces

10 Drug Half-Life The amount of time required for the plasma drug level to be reduced by one half It is either measured in minutes, hours, or days depending on the drug Critical information in determining how much of what drug to utilize Drug steady state The amount taken is equal to the amount excreted Drugs with long half-lives may take days or weeks to reach steady state

11 Effects of Physical Activity on Pharmokinetics
Exercise decreases the absorption after oral administration Exercise increases absorption after intramuscular or subcutaneous administration due to the increased rate of blood flow Exercise has an influence on the amount of a drug that reaches the receptor site

12 Legal Concerns in Administering Versus Dispensing Drugs
Defined as a single dose of medication to be used by a patient Dispensing constitutes providing a sufficient quantity to be used for multiple doses By law, only licensed persons may prescribe or dispense prescription drugs for an athlete ATC’s are not allowed to dispense medication unless allowed by state licensure

13 Administering Over the Counter Drugs
ATC may be allowed to administer a single dose of nonprescription medication Rules relative to secondary schools Oral medications vs. wound medication College and professional athletes Most are of legal age and are allowed to use whatever nonprescription drugs they choose ATC must still use reasonable care and be prudent about types of medication provided In all cases, actions should be performed under the supervision of a physician

14 Record Keeping Must maintain accurate and up to date medical records
Should include the following in log quantity of medication given method of administration Should be aware of state regulations relative to ordering, prescribing, distributing, storing and dispensing of the medications Obtaining legal counsel, working w/ state boards of pharmacy, student health clinic, physicians and establishing policies to minimize violating state laws

15 Record Keeping -ATC’s must maintain accurate and up to date medical records
Name Complaint Current medications Any known drug allergies Name of medication Lot number Expiration Date Quantity of medication given Method of administration Date and time of administration

16 Labeling Requirements (federally mandated)
Name of product Name and address of manufacturer, packer or distributor Net contents of package Name of active ingredients and quantity of certain other ingredients Name of any habit forming drug contained Cautions and warnings to protect consumer Adequate directions for safe, effective use Expiration date and lot number

17 Legal liability if drugs removed from original packaging and dispensed
Nonprescription drugs should not be repackaged w/out meeting labeling criteria All drugs dispensed from the athletic training room must be properly labeled Legal liability if drugs removed from original packaging and dispensed Unable to review contents, dosage, directions and precautions (information needed for safe use) Same liability associated with providing prescription medication

18 Safety in Use of Pharmaceuticals
No drug is completely safe and harmless Any drug under the correct conditions can be potent and dangerous, w/ every individual reacting differently Athlete must be instructed on specifics of medications (when to, how to and w/ what medication should be taken with) Drug Responses Individuals react differently to the same medications, w/ different conditions causing altered effects of drugs Drugs can change with aging and relative to how they are administered Alcohol ingestion w/ medications should be avoided

19 Alcohol is a CNS depressant and can increase or decrease effects of other drugs
Also used in many liquid preparations Medication can potentially effect certain physiologic functions related to dehydration (sweating, urination, and the ability to control and regulate body temperature) Can cause fluid depletion, further complicating illness, or make individuals sensitive to sunlight increasing risk of sunburn and allergic reactions Different diets may impact absorption rate Consumption of acidic foods such as fruit, carbonated drinks and vegetable juice may cause adverse reactions ATC must know their athlete’s in order to avoid potential adverse reactions

20 Buying Medication Pharmacist is a vital resource, assisting in selection and purchase of nonprescription drugs, suggesting less expensive generic drugs, and acting as a general advisor Properly storing medication is critical Keep in locked cabinet Maintain original container Store away from direct light, heat, damp places and extreme cold

21 Traveling with Medications
When traveling with a team or individually the athlete should be advised to do the following relative to medications Medication should not be stored in a bag/luggage but carried by the athlete taking it Sufficient supply should be packaged in case of emergency Make sure there is a source of medication while traveling Take copies of written prescriptions Keep medication in original container If traveling internationally, understand restrictions of individual boundaries

22 Selected Therapeutic Drugs to Treat the Athlete
Widespread use in athletics and general society Pharmaceutical labs develop compounds in vitro and then test, retest, and refine drugs in vivo before submitting it to the Food and Drug Administration (FDA) Number of texts and databases are available for reference to determine appropriateness and effectiveness of medications for different conditions

23 Drugs to Combat Infection
Local Antiseptics and Disinfectants Antiseptics are substances that can be placed on living tissue for killing bacteria or inhibiting growth Disinfectants are used to combat microorganisms but should be applied to non-living objects Germicides (generic name) designed to destroy bacteria, fungicides, sporicides and sanitizers

24 Alcohol Phenol Most widely used skin disinfectant
Ethyl alcohol (70% by weight) and isopropyl alcohol (70% by weight) are equally effective Inexpensive and nonirritating, kill bacteria immediately with the exception of spores No long lasting germicidal action, can be used as an antiseptic or astringent 70% solution can be used to disinfect instruments Also can be utilized as mild anesthetic and topical skin dressing when combined with 20% benzoin Phenol Early antiseptic and disinfectant in medical profession Used to control disease organisms Found in various concentrations and emollients Derivatives include, resorcinol, thymol, and common house cleaner Lysol

25 Halogens Oxidizing agent
Chlorine, bromine, fluoride (used for antiseptic effect) Iodophor or halogenated compounds create a much less irritating solution than tincture of iodine Betadine solution- excellent germicide, very effective for skin lesions, abrasions and lacerations Oxidizing agent Hydrogen peroxide is commonly used in the athletic training room Readily decomposes in presence of organic substances and has little use as an antiseptic Cleanses infected cutaneous and mucous membranes Dilute solution can be used to treat inflammatory mouth and throat conditions

26 Antifungal Agents Antibiotics
Medicine used to treat fungi (epidermophyton, trichophyton, and candida albicans) Numerous antifungal agents Some can be used against deep seated fungal infections Others are administered orally Must be carefully monitored by physician Antibiotics Chemical agents that are produced by microorganisms Interferes w/ necessary metabolic processes of pathogenic microorganisms

27 Used topically or as systemic medication
Indiscriminate use can produce hypersensitivity and prevent development of natural immunity or resistance to subsequent infections Must be carefully controlled by physician A number of antibiotics are available Penicillin Most important antibiotic Useful in skin and systemic infections Interferes w/ metabolism of bacteria Bacitracin Antibacterial agent Tetracycline Wide group of antibiotics that have broad antibacterial spectrum Usually oral, modifies infection rather than eradicating it completely

28 Erythromycin Sulfonamides Quinolones
Used for streptococcal infection and mycoplasma pneumoniae Same general spectrum as penicillin but can be used with individuals allergic to penicillin Sulfonamides Group of synthetic antibiotics Make pathogens vulnerable to phagocytes and certain enzymatic actions Quinolones New group of antibiotics with broad spectrum of activity Must be carefully monitored for adverse effects

29 Drugs for Asthma Used to treat chronic inflammatory lung disorder
National Asthma Education and Prevention Program has established guidelines for diagnosis and treatment Goals of asthma therapy are to prevent chronic and troublesome symptoms, maintain normal lung function, prevent exacerbation and provide adequate pharmacotherapy with minimal adverse effects Portable hand-held inhalers are available Meter dosed inhalers (pressurized canister) Dry powder inhalers Nebulizer Often individuals become dependent on inhalers Treatment should not just be drug based

30 Drugs that Inhibit Pain and Inflammation
Pain Relievers Numerous drugs and procedures can be used Reasons for effectiveness Excitatory effect on an individual impulse is depressed Individual impulse is inhibited Perceived impulse is decreased Anxiety created by pain or impending pain is decreased

31 Counterirritants and Local Anesthetics
Analgesics give relief by causing systemic and topical analgesia Application causes local increases in circulation, redness, rise in skin temperature Mild pain can often be reduced w/ counterirritants Examples include Liniments Analgesic balms Spray coolants Alcohol Menthol Cold Local anesthetics (injected by physician)

32 Narcotic Analgesics Most derived from opium or are synthetic opiates (morphine and codeine) Depress pain impulse and respiratory center Examples include Codeine (morphine like action, found in cough suppressants) Morphine (dangerous due to respiratory effects, habit forming qualities) Propoxyphene hydrochloride (slightly stronger than aspirin and can be fatal if mixed with sedatives or depressants) Meperidine (Demerol - substitute for morphine, effective when given intravenously or intramuscularly)

33 Non-narcotic Analgesics and Antipyretics
Designed to suppress all but most serious pain w/out losing consciousness Acetaminophen Tylenol - effective analgesic and antipyretic but has no anti-inflammatory activity Does not irritate GI system and is often replacement for aspirin in non-inflammatory conditions Over-ingestion can lead to liver damage

34 Drugs to Reduce Inflammation
Acetylsalicylic Acid (Aspirin) Widely used analgesic, anti-inflammatory, antipyretic and abused drug Helps reduce pain, fever and inflammation Adverse reactions generally GI related Over-ingestion can lead to ear ringing and dizziness, Reye’s syndrome (adolescents) Allergic reactions result in anaphylaxis -- asthmatics may be at risk for reactions Should be avoided w/ contact sports as it prolongs clotting time

35 Nonsteroidal Anti-inflammatory Drugs (NSAID’s)
Anti-inflammatory, antipyretic and analgesic properties Inhibit prostaglandin synthesis and effective for osteo- and rheumatoid arthritis Used primarily to reduce pain, stiffness, swelling, redness, fever associated w/ localized inflammation Fewer side effects and longer duration than aspirin

36 Should not be used in place of acetaminophen or aspirin for headaches or increased temperature
Individuals w/ nasal polyps, associated bronchospasm or history of anaphylaxis should not receive NSAID’s Can cause GI reactions, headache, dizziness, depression, tinnitus, Taken in conjunction w/ heavy alcohol use can produce stomach bleeding

37 Corticosteroids Used primarily for chronic inflammation of musculoskeletal and joint problems Prolonged use can create complications Fluid and electrolyte disturbances Musculoskeletal and joint impairment Dermatological problems Neurological impairment Endocrine dysfunction Ophthalmic conditions Metabolic impairment Cortisone is primarily injected Can have negative effect on ligaments and tendons Also administered through iontophoresis and phonophoresis

38 Drugs that Produce Skeletal Muscle Relaxation
Include methocarbamol (Robaxin) and carisoprodol (Soma) Due to overall relaxation effect, physicians believe these are less specific to muscle relaxation than once believed (also cause drowsiness) Used to eliminate muscle guarding and spasm Do not appear to be superior analgesics or sedatives in either acute or chronic conditions

39 Drugs Used to Treat Gastrointestinal Disorders
Includes stomach upset, gas formation due to food incompatibilities, acute or chronic hyperacidity Poor eating habits may lead to digestive dysfunction such as diarrhea or constipation Antacids Neutralize acidity in upper GI, reducing pepsin activity (particularly on mucosal nerve endings Relief of acid indigestion, heart burn, peptic ulcers

40 Antiemetics Sodium bicarbonate or baking soda are popular
Antacids w/ magnesium tend to have laxative effect Those w/ aluminum and calcium cause constipation Overuse can cause electrolyte imbalance Antiemetics Used to treat nausea and vomiting Working Locally Work on mucosal lining of stomach (may be more placebo) Working Centrally Affect brain, making it less sensitive to nerve impulses from inner ear and stomach Variety of meds available, but may cause drowsiness

41 Cathartics (laxatives)
Carminatives Provide relief from flatulence (gas) Inhibit gas formation and aid in expulsion Cathartics (laxatives) Must be under direct supervision of physician Constipation may be symptomatic of serious disease Indiscriminate use may render athlete unable to have normal bowel movements May cause electrolyte imbalance Antidiarrheals Diarrhea tends to be a symptom, not a disease Result of emotional stress, allergies, adverse drug reactions, or different intestinal problems

42 Antidiarrheal (continued)
Acute diarrhea Accompanied by chills, vomiting, intense abdominal cramps/pain Will typically run course and stop when irritating agent removed from system Chronic diarrhea May lasts for days or weeks and may be the result of more serious disease states Treat with Kaolin (absorb chemicals and pectin), substances that add bulk to stool Systemic agents (except Imodium AD) are prescription drugs Most are opiate derivatives and will cause drowsiness, dry mouth, and constipation Do not treat antibiotic induced diarrhea as it may be protective symptom in antibiotic induced psuedomembranous colitis

43 Histamine-2 Blockers Reduce stomach acid output by blocking histamine on certain stomach cells Used to treat peptic and gastric ulcers and GI hypersecretory conditions Drug examples include Cimetidine (Tagamet) and ranitidine (Zantac)

44 Drugs Used to Treat Colds and Allergies
Nasal Decongestants Number of topical nasal decongestants available Prolonged use may cause rebound congestion and dependency Antihistamines Often added to decongestants Opposes histamine actions, but have little effects on the common cold Beneficial in allergies Impairs body’s ability to dissipate heat

45 Cough Medications Sympathomimetics
Suppress cough (antitussives) or produce fluid in respiratory system (expectorant) Few side effects from nonnarcotic antitussives and are not addictive Little evidence that expectorants are any more effective on reducing cough than simply drinking water Sympathomimetics May cause heat related problems Epinephrine (Epipen) ATC’s can receive instruction on use Used to treat anaphylaxis resulting from food or insect bites

46 Drugs to Control Bleeding
Vasoconstrictors Most often administered externally at sites of profuse bleeding Epinephrine or adrenaline commonly used Acts immediately, constricting vessels --very valuable in instances of epistaxis (nosebleed) Hemostatic Agents Drugs that immediately inhibit bleeding (under investigation) Thrombin

47 Anticoagulants Heparin Coumarin derivatives
Prolongs clotting time but will not dissolve clot once formed Controls extension of a thrombus already present Coumarin derivatives Acts by suppressing formation of prothrombin in the liver Given orally, they can be used to slow clotting time in certain vascular disorders

48 Drugs that Can Increase the Rate of Heat Illness
Some drugs may alter the body’s ability to thermoregulate Anticholinergics and antihistamines (decrease sweating mechanism) Sympathomimetic amines (may predispose athlete to heat stroke) Phenothiazines (impacts hot/cold temp. regulation) Diuretics (alters volume expansion and cutaneous vasodilation) ATC must be aware of potential risk of medications relative to heat illnesses

49 Substance Abuse Among Athletes
Drug use and performance enhancing agents in athletics Substance abuse has no place in athletics Use and abuse of substances can have a profound effect on performance Athletic trainer must be knowledgeable about substance abuse in athletic population and should be able to recognize signs that athlete may be engaged in substance abuse

50 Performance Enhancing Substances (Ergogenic Aids)
Stimulants Used to increase alertness, reduce fatigue, increase competitiveness and hostility Psychomotor stimulant drugs Amphetamines and non-amphetamines Produces rapid turnover of catecholamines, which have strong effect on nervous and cardiovascular systems, metabolic rates, temperature and smooth muscle Sympathomimetic drugs Work on adrenergic receptors (those that release catecholamines) Cause mental stimulation and increased blood flow but can cause elevated blood pressure, headache, increased and irregular heart beat, anxiety and tremors

51 Amphetamines and cocaine are the two psychomotor drugs most commonly seen in athletics
Sympathomimetic drugs are a difficult problem for the USOC as they are often found in cold remedies Some products have been approved for asthmatics (B2 agonists) Before engaging in competition a team physician must notify the USOC Medical Subcommission in writing about athlete’s use

52 Amphetamines Synthetic alkaloids (potent and dangerous)
Injected, inhaled, taken as tablets Most widely used for performance enhancement Can produce euphoria w/ heightened mental status until fatigue sets in, accompanied by nervousness, insomnia, and anorexia In high doses, will reduce mental activity and decrease performance Athlete may become irrational chronic use causing individual to become “hung up” in state of repetitious behavioral sequences

53 Can lead to amphetamine psychosis, manifesting in auditory and visual hallucinations and delusions
Physiologically, high doses can cause mydriasis (abnormal pupil dilation), increased blood pressure, hyperreflexia and hyperthermia Believed to improve performance - promote quickness and endurance, delay fatigue, increase confidence causing increased aggressiveness Studies indicate the opposite --create increased risk for injury, exhaustion and circulatory collapse

54 Caffeine Found in coffee, tea, cocoa and cola
CNS stimulant, diuretic and stimulates gastric secretion In moderation it will cause cerebral cortex and medular centers stimulation, causing wakefulness and mental alertness Large amounts will cause elevated blood pressure, changes in heart rate, increased plasma levels of epinephrine, norepinephrine and renin --impacting coordination, sleep, mood, behavior and thinking processes

55 Habitual user that ceases use may go through withdrawal
Adverse effects include, tremors, nervousness, headaches, diuresis, arrhythmia, restlessness, hyperactivity, irritability, dry mouth, tinnitus, ocular dyskinesia, scotomata, insomnia and depression Habitual user that ceases use may go through withdrawal Suffer headache, drowsiness, lethargy, rhinorrhea, irritability, nervousness, depression and lost interest in work Believed to act as ergogenic aid during prolonged activity Banned by USOC as stimulant in high doses (12 micrograms/milliliter)

56 Narcotic Analgesic Drugs
Derived from opium or synthetic opiates Morphine and codeine are made from alkaloid of opium Used for management of moderate/severe pain Risk physical and psychological dependency Beta Blockers Block of sympathetic nerve ending receptor Primarily used for hypertension and heart disease. Used for sports requiring steadiness Adrenergic agent that inhibits catecholamines Relax blood vessels, slows heart rate and decreases cardiac output and heart contractility

57 Diuretics Increase kidney excretion by decreasing kidney resorption of sodium Excretion of potassium and bicarbonate may also occur Used for variety of cardiovascular and respiratory conditions In sports, misused for weight loss and decreasing concentration in urine

58 Anabolic Steroids Synthetic chemical (structure resembles sex hormone, testosterone) Androgenic effects Growth, development and maintenance of reproductive tissues, masculinization Anabolic effects Promote nitrogen retention leading to protein synthesis - causing increased muscle mass and weight, general growth and bone maturation Goal is to maximize this effect Can have deleterious and irreversible effects causing major threats to health Use most commonly seen in sports that involve strength and power

59 Tetrahydrogestrinone (THG)
Believed to be undetectable Designer steroid that is structurally similar to gestrinone and trenbolone Derived from other anabolic steroids Banned by USADA Cannot be legally marketed without FDA approval

60 Androstenedione Weak androgen produced primarily in testes and in lesser amounts by adrenal cortex and ovaries Increases testosterone in men and particularly women Effects last a few hours No scientific evidence to support or rebuke efficacy or safety of using this ergogenic aid Banned by IOC, NFL, NCAA, and minor league baseball Contains steroid hormones May result in breast enlargement, testicular shrinkage (males) or facial/body hair, voice deepening, and clitoral enlargement (females)

61 Human Growth Hormone (HGH)
Produced in somatotrophic cells of anterior pituitary and released into circulatory system Amount released varies with age Can be produced synthetically Results in increases muscle mass, skin thickness, connective tissue in muscle, organ weight Can produce lax muscles and ligaments during periods of growth Increases body length, weight and decreases body fat %

62 Difficult to detect so use is on the rise
Little current information on the effects of HGH No proof that increased HGH and weight training contributes to strength and muscle hypertrophy Can cause premature closing of growth plates, acromegaly which may also result in diabetes mellitus, cardiovascular disease, goiter, menstrual disorders, decreased sexual desire and impotence

63 Blood Reinjection (Blood Doping, Packing or Boosting)
Endurance, acclimatization and altitude make increased metabolic demands for the body, requiring increased blood volume and RBC’s Can replicate physiological responses by removing 900 ml of blood and reinfusing is after 6 weeks (allows time to replenish supply) Can significantly improve performance While unethical, it can also prove to be dangerous Risks involve allergic reactions, kidney damage, fever, jaundice, infectious disease, blood overload (circulatory or metabolic shock)

64 Recreational Substance Abuse Among Athletes
It occurs among athletes Desire to experiment, temporarily escape, be part of the group Can be abused and habit forming Drug used for non-medical reasons with the intent of getting high, or altering mood or behavior

65 Psychological vs. Physical Dependence
Psychological dependence is the drive to repeat the ingestion to produce pleasure or avoid discomfort Physical dependence is the state of drug adaptation that manifests self in form of tolerance When cease consumption abruptly unpleasant withdrawal occurs Tobacco Use Cigarettes, cigars & pipes are increasingly rare in athletics Smokeless tobacco and passive exposure to others continues to be an ongoing problem

66 Smoking Seriously impacts performance for those that are highly sensitive Associated with 4,700 different chemicals 10 inhalations can cause average maximum decrease in airway conductance of 50% (secondhand also) Reduces oxygen carrying capacity of blood Aggravates and accelerates heart muscle cell stimulation through over-stimulation of sympathetic nervous system Decreases lung capacity and maximum breathing capacity, also decreases pulmonary diffusion Accelerates thrombolic tendency Carcinogenic factor in lung cancer and contributes to heart disease

67 Nicotine is the addictive chemical in tobacco- one of the most toxic drugs
Causes elevated blood pressure, increased bowel activity, and antidiuretic action Smokeless Tobacco Loose leaf, moist, dry powder, and compressed Posses serious health risk Bad breath Stained teeth Tooth sensitivity to heat and cold Cavities and gum recession Tooth bone loss Leukoplakia Oral and throat cancer Major substance ingested is nitrosonornicotine Absorbed through mucous membranes More addictive habit w/out exposure to tar and carbon monoxide Will increase heart rate

68 Alcohol Use Most widely used and abused substance with athletes
Depresses CNS Absorbed from digestive tract into bloodstream Absorption affected by drinks consumed, rate of consumption, concentration and amount of food in stomach Can be oxidized by liver at 2/3 of an ounce per hour If excess is in blood stream .1% - lose motor function .2%-.5% symptoms become more profound and life threatening

69 Metabolism can not be accelerated
Athlete abusing alcohol may exhibit the following Mood and attitude changes Missed practices Isolation Fighting or inappropriate outburst of violence Changes in appearance Hostility Complaints from family Changes in peer group

70 Drug Use Cocaine CNS stimulant w/ short duration effects (intense)
Produces immediate feeling of euphoria, excitement, decreased fatigue and heightened sexual drive Long term use results in psychological tolerance and dependence Long term effects include Nasal congestion, damage to cartilage and mucous membranes of nose, bronchitis, loss of appetite, convulsions, impotence, cocaine psychosis w/ paranoia, depression, hallucinations, and disorganized mental function Overdose can lead to Tachycardia, hypertension, extra heartbeats, coronary vasoconstriction, strokes, pulmonary edema, aortic rupture and sudden death

71 Marijuana (carcinogenic drug)
Can be taken in many forms including snorted, intravenously, or smoked (freebased) In form of crack - very short term rush, followed by depression Sudden stimulation w/ crack can cause cardiac or respiratory failure Marijuana (carcinogenic drug) Formerly most abused drug in Western society Similar components and cellular changes as tobacco Can lead to respiratory disease,asthma, bronchitis, lowered sperm count and testosterone levels, limited immune functioning and cell metabolism Causes increased pulse rate and can cause decrease in strength Psychologically causes diminution of self-awareness and judgement, slower thinking and short attention span

72 Managing a Drug Overdose
Has also been found to alter the anatomical structures suggesting irreversible brain damage Contains cannabinoids (can store like fat cells) May remain in the body and brain for weeks and months resulting in cumulative deleterious effects Managing a Drug Overdose In the event of an overdose, EMS should be contacted as well as the poison control center immediately Athletic trainer should be certain that the correct steps have been taken either by phone or going to deal with the athlete in person

73 Drug Testing in Athletics
Purpose is to identify individuals who have problems with drug abuse Controversial topic NCAA and USOC routinely test Began at the Olympics in 1968 and has since expanded nationally (USOC and NCAA) and internationally Institution of testing and education Performed to ensure health of athletes and fair practices Mandatory and random testing occurs at both levels

74 The Drug Test Slight differences between NCAA and USOC, mostly in area of selection NCAA requires all athletes to sign consent form agreeing to participate in testing throughout the year USOC tests randomly throughout the year and before USOC sanctioned events During the test, athlete provides identification, and 2 samples under direct supervision One for testing and confirmation, second for reconfirmation If positive, athlete is subject to sanctions

75 Sanctions for Positive Tests
NCAA First time positive in NCAA results in minimum one year suspension; will undergo random testing throughout the year Must test negative prior to reinstatement However, additional positives can result in lifetime disqualification from NCAA USOC Sanctions range from 3 months - 24 months depending on the drug for a first time offense Lifetime ban for subsequent positive tests

76 Banned Substances Both NCAA and USOC have a banned substance list for athletes Includes performance enhancing drugs and street or recreational drugs, as well as OTC medications Includes 4,600 different medications USOC is more extensive than NCAA because it is also subject to IOC rules Athletic trainer working w/ athletes who may be tested for drugs by NCAA or world-class or Olympic athletes governed by USOC should be familiar w/ the lists of banned drugs and substances
