ABDULLAH AL-SUBAIE, MBBS, FRCP (C) PROFESSOR OF PSYCHIATRY Substance use/ Prof. Subaie 1 ALCOHOL & SUBSTANCE ABUSE
TYPES OF ABUSED SUBSTANCES Anxiolytics and hypnotics Opioids Stimulants Hallucinogens Cannabis Organic solvents Substance use/ Prof. Subaie 2
Prevalence: Substance use/ Prof. Subaie 3
Prevalence: Substance use/ Prof. Subaie 4
DSM-IV Criteria for Substance Intoxication Substance use/ Prof. Subaie 5 A. The development of a reversible substance-specific syndrome due to recent use of a substance. Different substances may produce similar or identical syndromes. B. Clinically significant maladaptive behavioral or psychological changes that are due to the effect of the substance on the central nervous system (eg, belligerence, mood lability, cognitive impairment, impaired judgment, impaired social or occupational functioning) and develop during or shortly after use of the substance. C. The symptoms are not due to a general medical condition and are not better accounted for by another mental disorder.
DSM-IV Criteria for Substance Withdrawal Substance use/ Prof. Subaie 6 A. The development of a substance-specific syndrome due to the cessation of (or reduction in) substance use that has been heavy and prolonged. B. The substance-specific syndrome causes clinically significant distress or impairment in social, occupational, or other important areas of functioning. C. The symptoms are not due to a general medical condition and are not better accounted for by another mental disorder.
DSM-IV Diagnostic Criteria for Substance Dependence - 1 Substance use/ Prof. Subaie 7 A. Maladaptive pattern of substance use, leading to clinically significant impairment or distress, as manifested by three (or more) of the following, occurring at any time in the same 12-month period: 1. Tolerance, as defined by either of the following: (a) a need for markedly increased amounts of the substance to achieve intoxication or desired effect (b) markedly diminished effect with continued use of the same amount of the substance 2. Withdrawal, as manifested by either of the following: (a) the characteristic withdrawal syndrome for the substance (refer to criteria of withdrawal of the specific substance) (b) the same (or closely related) substance is taken to relieve or avoid withdrawal symptoms.
DSM-IV Diagnostic Criteria for Substance Dependence - 2 Substance use/ Prof. Subaie 8 (3) the substance is often taken in larger amounts or over a longer period than was intended (4) there is a persistent desire or unsuccessful efforts to cut down or control substance use (5) a great deal of time is spent in activities necessary to obtain the substance (eg, visiting multiple doctors or driving long distances), use the substance (eg, chain-smoking), or recover from its effects (6) important social, occupational, or recreational activities are given up or reduced because of substance use (7) the substance use is continued despite knowledge of having a persistent or recurrent physical or psychological problem that is likely to have been caused or exacerbated by the substance (eg, current cocaine use despite recognition of cocaine-induced depression, or continued drinking despite recognition that an ulcer was made worse by alcohol consumption)
DSM-IV Diagnostic Criteria for Substance Dependence - 3 Substance use/ Prof. Subaie 9 Specify if: with physiological dependence: evidence of tolerance or withdrawal (i.e, either item 1 or 2 is present) without physiological dependence: no evidence of tolerance or withdrawal (i.e, neither item 1 nor 2 is present)
WHEN TO SUSPECT SUBSTANCE ABUSE / DEPENDENCE ? 1 Substance use/ Prof. Subaie 10 When medical or psychiatric problems may be related to alcohol or drugs. If patient requests certain drugs for unsatisfactory reasons. When needle tracks and thrombotic veins are found. Finding scars of previous abscesses. When forearms are concealed.
WHEN TO SUSPECT UBSTANCE ABUSE / DEPENDENCE ? 2 Substance use/ Prof. Subaie 11 In cases of self neglect, and school or occupational decline. In history of former friends loss and joining the “drug culture.” In history of thefts and prostitution. When urine tests positive (except LSD and solvents). When Gamma–Glutmyle–transferase (GGT) and MCV are elevated.
PREVALENCE ISSUES - 1 Substance use/ Prof. Subaie 12 Availability: Prescribed e.g. Benzodiazepines Legal e.g. alcohol & nicotine Illegal e.g. cocaine, hash

PREVENTION Substance use/ Prof. Subaie 18 Preventive measures Improved education Increased restrictions Of availability Of advertising
COMPLICATIONS Substance use/ Prof. Subaie 19 General medical complications e.g. AIDS, endocarditis Local effects of I.V. injections e.g. thrombosis. Frequent intoxication leading to poor functioning, failure of social relations, accidents, family problems and neglect. Debts due to expensive illicit drugs leading to prostitution and crime. Death.
ALCOHOL ABUSE / DEPENDENCE Substance use/ Prof. Subaie 21 PREVALENCE: In England, 6% of men & 1% of women admitted to consumption of >50 units/week. Lifetime prevalence rate was 0.45% among Chinese in Shanghai & 23% among Native Mexican-Americans Dependence is usually established in mid-forties for men and a few years later for women. Dependence is also increasing in teenagers and women. Dependence is generally more common in disadvantaged areas. Age, sex: Young males but rate in females is rising. Occupation: Executives, service men, journalists, Salesmen and movie industry. 1 unit= 8 gm or 1 centiliter
ALCOHOL ABUSE / DEPENDENCE Substance use/ Prof. Subaie 22 PERSONALITY TRAITS: Self-indulgence Anxiety Painful reality is denied and pleasure is obtained by immediate oral gratification (drinking) “Alcoholism is a conditioned behavioral response” “Alcoholism is a series of transactions designed to obtain personal advantage or hide deficiencies” Stress leads to anxiety that is relieved by alcohol
ALCOHOL ABUSE / DEPENDENCE Substance use/ Prof. Subaie 23 PHYSICAL COMPLICATIONS SUCH AS: G.I.T.: Gastritis and peptic ulcer, esophageal varices, acute and Chronic pancreatitis, hepatitis and cirrhosis. C.N.S.: Peripheral neuropathy, dementia, epilepsy. Others: Anemia, episodes of hypoglycemia, obesity, Cardiomyopathy, Myopathy Alcohol fetal syndrome: Facial abnormalities, low birth weight, low intelligence and over activity.
ALCOHOL ABUSE / DEPENDENCE Substance use/ Prof. Subaie 24 NEUROPSYCHIATRIC COMPLICATIONS: 1. INTOXICATION STATES: Blackouts: amnesia to events that occur during the period of intoxication. Idiosyncratic intoxication: markedly changed behavior (usually aggressive) occurring within minutes of drinking a small amount of alcohol. Other effects: Mood: euphoria/dysphoria, irritability Cognition: sedation, memory & judgment impairment Behavior: disinhibition, aggression, violence, accident proneness.
ALCOHOL ABUSE / DEPENDENCE Substance use/ Prof. Subaie 26 TOXIC AND NUTRITIONAL STATES: 1.Wernicke’s encephalopathy: due to thiamin deficiency leading to bilateral degeneration of the posterior hypothalamus, hippo- campus and mamillary bodies. Features include: delirium, ataxia and ophthalmoplegia. 2.Korsakov’s syndrome (alcohol amnestic syndrome): Features include: prominent disturbance of recent memory in the absence of generalized intellectual impairment (Immediate recall is good but recent memory is impaired). Confabulation and disorientation to time may occur. New learning is impaired. Occurs after prolonged use. On CT scan: Ventricles may be enlarged and sulci may be widened. CT changes may partially resolve on abstinence.
ALCOHOL ABUSE / DEPENDENCE Substance use/ Prof. Subaie 27 ASSOCIATED COMORBIDITY & COMPLICATIONS: Depression/ Suicide Anxiety Personality changes Pathological jealousy Sexual dysfunction Hallucinations Social damage Crimes Road traffic accidents Occupational problems Family conflicts and losses
ALCOHOL ABUSE / DEPENDENCE Substance use/ Prof. Subaie 28 MANAGEMENT: 1. Assess: - Extent of drinking - Evidence of dependence - Alcohol related disability 2. Arrange for and treat withdrawal symptoms: - Sedation - Thiamin and Vitamin B supplements - Rehydration
ALCOHOL ABUSE / DEPENDENCE Substance use/ Prof. Subaie 29 MANAGEMENT: 3. Treat urgent psychiatric or medical problems: 4. Arrange for rehabilitation and long term treatment: Of medical and psychiatric disability Resolving interpersonal problems Social support ( work, law, finance, interests) Individual and / or group counseling Self help group e.g. alcohol anonymus Help for family Disulfiram (antabuse)- inhibits acetaldehyde dehydroginase…
ALCOHOL ABUSE / DEPENDENCE Substance use/ Prof. Subaie 30 PROGNOSIS: Generally poor: At 6/12: 25% remain abstinent At 18/12: 10% remain abstinent Good prognostic factors include: Good insight Strong motivation Supportive family Stable job Ability to form good relationship Control of impulsivity and ability to defer gratification
OUTCOME Outcome depends more on the patient than on the treatment Substance use/ Prof. Subaie 31
CANNABIS Substance use/ Prof. Subaie 32 Derived from the plant Cannabis sativa Effects vary with: dose, user’s expectation and social setting Exaggerates the preexisting mood (euphoria or dysphoria) Physical dependence and withdrawal symptoms do not occur Acute intoxication may lead to psychosis while chronic use may lead to “amotivational syndrome”
ORGANIC SOLVENTS (INHALENTS) Substance use/ Prof. Subaie 33 ADHESIVES, CLEANING FLUIDS, PETROL, AEROSOLS, BUTANE GAS. Most common among teenagers. Intoxication leads to drunkenness, delirium, uncoordinated gait, nausea, vomiting, and coma. Visual hallucinations are common. More psychological than physical dependence. It has a neurotoxic effect leading to peripheral neuropathy and cerebellar dysfunction. Over dosage may be fatal and chronic use may lead to psychosis. Very cheap and easily obtained. Due to: hepatorenal, brain & bone marrow toxicity, bronchial asthma & cardiorespiratory arrest, coma, asphyxiation with plastic bags, trauma …
STIMULANTS Substance use/ Prof. Subaie 34 AMPHETAMINES AND COCAINE Lead to elevation of mood, over-activity, insomnia, over- talkativeness, and anorexia. Cardiac arrhythmia and malignant hypertension may result from high doses. Death Prolonged use may result in paranoid psychosis resembling schizophrenia Physical dependence is not severe Withdrawal may lead to severe depression and suicide Treatment includes abstinence, antidepressants and neuroleptics Due to: hyperpyrexia, coma, CV shock, fits…
HALLUCINOGENS Substance use/ Prof. Subaie 35 LSD, DISMETHYL TRYPTAMINE AND ANTICHOLINERGIC DRUGS Lead to distortion or intensification of perceptions or frank hallucinations. Time moves slowly Profound meaning of ordinary events. Body image distortions and depersonalization may occur. Experience may be pleasant, distressing, or frightening leading to dangerous unpredictable behavior. Physical effects include hypertension Flashbacks may occur More psychological than physical dependence Treatment is diazepam or phenothiazines (avoid in case of anticholinergic over-dose)
OPIOIDS Substance use/ Prof. Subaie 36 HEROIN, MORPHINE, CODEINE AND PETHEDIN Lead to immediate effects of euphoria, analgesia, reduced appetite, respiratory depression, drowsiness, gastrointestinal spasms, fits… Tolerance develops rapidly Withdrawal symptoms: craving, agitation, insomnia, pains and arthralgia, abdominal cramps, runny nose and eyes, sweating, diarrhea, piloerection, dilated pupils, tachycardia and disturbed temperature control. Withdrawal starts within 6 hours, peaks in 24–48 hours and it is not life threatening Short-term treatment includes: relief of withdrawal symptoms. Long-term treatment includes: methadone replacement and rehabilitation Treatment outcome remains poor in the best hands. Death results in about: 10%-20% in 7 years.
