Drug abuse or Substance abuse refers to the use of certain chemicals for the purpose of creating pleasurable effects on the brain, rather than for their intended therapeutic medical purposes. The problem has been increasing at alarming rates globally, especially among young adults.

• Narcotic Abuse (Opioid Use Disorder): The use of narcotic drugs (opioids) to seek feelings of well-being, euphoria, or numbness, other than for pain killing. It is a complex set of behaviors typically associated with misuse, developing over time with higher drug dosages.
• Drug Dependence: A state resulting from the interactions of a person and a drug in which the person has a compulsion to continue taking the drug to experience pleasurable psychological effects and sometimes to avoid severe discomfort due to withdrawal. It is divided into:
  • Physical dependence: The body adapts to the drug, and when a person abruptly stops using narcotics, they develop physiological withdrawal symptoms.
  • Psychological dependence: Using the drug for personal satisfaction and craving it, even if the risks and harms are known to the user.
• Drug Tolerance: A physiological state where more of the drug is needed to produce the same original response. This usually happens with chronic use of drugs causing dependence, pushing the user to take dangerously high doses.

Addiction is a biopsychosocial disorder. The reasons for narcotic abuse and dependence include:

• Curiosity and Experimentation: Wanting to know the taste/effect of the drug and wanting to belong or be accepted in certain peer groups (Peer Pressure).
• Escapism and Stress: Intermittent use of drugs for social or emotional reasons (e.g., depression, anxiety, PTSD, break-ups, financial burdens, unemployment) to relieve stress or forget problems.
• Iatrogenic / Irrational Drug Use: Continuous use of a prescribed narcotic for a long time (e.g., chronic pain management) leading to accidental dependence.
• Genetics and Family History: A family history of substance abuse greatly increases susceptibility to addiction.
• Availability and Accessibility: Easy access to prescription drugs (e.g., from family medicine cabinets or occupational exposure for healthcare workers) or illicit street drugs.
• Self-Medication: People with underlying mental health conditions (like ADHD, Depression, or severe anxiety) may use narcotics to self-medicate.
• Socio-economic factors: Poverty, high work pressure, illegal relationships, and weak drug enforcement laws.

• Accidents and severe cognitive impairment.
• Respiratory illness, pneumonia, and ultimately respiratory arrest.
• Cardiovascular illness and Hypovolemia/hypotension.
• Seizures, delirium, and coma.
• Opioid hyperalgesia: A paradoxical increase in pain sensitivity.
• Infectious Complications (from IV drug use): Infections at the injection site (abscesses, cellulitis), infective endocarditis, and transmission of blood-borne viruses like HIV and Hepatitis B/C.
• Severe constipation and bowel obstruction.

Intoxication can range from mild to life-threatening. Mental status effects include euphoria, sedation, decreased anxiety, a sense of tranquility, and indifference to pain. Severe intoxication leads to the classic Opioid Overdose Triad.

Other signs include: Slurred speech, hypothermia, cyanosis, needle marks/tracks, and increased sphincter tone leading to urinary retention.

Withdrawal occurs when a physically dependent person stops taking the drug. Symptoms are intensely uncomfortable but rarely fatal.

• Early Symptoms: Anxiety, agitation, craving, yawning, running nose (rhinorrhea), excessive salivation, and sweating.
• Late Symptoms: Wide (dilated) pupils (mydriasis), tachypnea, tachycardia, severe muscle aches and bone pain, tremors, lack of appetite, severe abdominal cramps, diarrhea, nausea, and vomiting.

• Immediate Triage: Patients arriving with suspected narcotic overdose are highly critical. They are often brought in unconscious by bystanders or EMS.
• A-B-C Approach:
  • Airway: Check if the airway is patent. Clear vomitus or secretions.
  • Breathing: Assess respiratory rate and depth. If the patient is apneic or taking shallow breaths (e.g., 4 breaths/min), initiate bag-valve-mask (BVM) ventilation with 100% oxygen immediately.
  • Circulation: Assess pulses and blood pressure.
• Move to Resuscitation Area: Any patient with a depressed level of consciousness and respiratory depression must be immediately moved to the Resuscitation/Emergency bay.

• Vital Signs: Continuous SpO2, cardiac monitoring, and frequent BP checks.
• Neurological Assessment: Check GCS (Glasgow Coma Scale) and examine pupils for miosis (pinpoint).
• Collateral History: Ask paramedics or bystanders about the scene (empty pill bottles, syringes, history of drug abuse).
• Screening Tools (for stable/conscious patients): Use the CAGE-AID questionnaire (Adapted to Include Drugs):
  1. Have you ever felt you ought to Cut down on your drug use?
  2. Have people Annoyed you by criticizing your drug use?
  3. Have you felt bad or Guilty about your drug use?
  4. Have you ever had an Eye-opener (used drugs first thing in the morning to steady nerves or get rid of a hangover)?
• Investigations:
  • Point-of-care capillary blood glucose (to rule out hypoglycemia causing coma).
  • Urine Toxicology screen (confirms presence of opiates).
  • Arterial Blood Gas (ABG) to check for hypoxia and hypercapnia.
  • ECG (to check for QTc prolongation or arrhythmias, especially with Methadone abuse).
  • Screening for HIV, Hepatitis B/C if IV drug use is suspected.

The primary goal is reversing respiratory depression. Secure IV access immediately.

Note on Antidote Administration: Administering Naloxone to a physically dependent patient will precipitate immediate and severe withdrawal symptoms. Be prepared for agitation, vomiting, and combativeness upon waking.

• ICU / High Dependency Unit (HDU): Patients requiring intubation, mechanical ventilation, or a continuous Naloxone infusion due to long-acting narcotic overdose (e.g., Methadone) must be admitted here.
• General Medical Ward / Toxicology Unit: Stable patients who are conscious and breathing adequately, but need observation for 24-48 hours to manage withdrawal and monitor for secondary complications (e.g., aspiration pneumonia).
• Psychiatric / Rehabilitation Center: Once medically cleared, patients with severe opioid use disorder should be transferred to specialized psychiatric or rehab centers for detox and long-term management.

The patient must be motivated and helped to appreciate the disadvantages of drug use. The withdrawal severity is often measured using the COWS (Clinical Opiate Withdrawal Scale). Management involves Medication-Assisted Treatment (MAT):

• Agonist Substitution Therapy: Substituting the abused drug with a controlled, long-acting opioid to taper them down slowly without euphoria.
  • Methadone: A long-acting synthetic opioid.
  • Buprenorphine: A partial opioid agonist, often combined with naloxone (Suboxone) to prevent IV abuse.
• Non-Opioid Symptomatic Control:
  • Clonidine: An alpha-2 agonist that heavily relieves autonomic withdrawal symptoms such as salivation, running nose, sweating, muscle aches, and anxiety.
  • Diazepam or Chlordiazepoxide: Benzos for severe anxiety or agitation.
  • Carbamazepine: 200-400mg BD to guard against seizures.
  • Loperamide / Antiemetics: For diarrhea and vomiting.
  • Vitamin B Complex & Multivitamins: For nutritional support.

Addiction is a chronic, relapsing disease. Medical detox is only the first step. Long-term treatment includes:

• Motivational Counseling: Show the patient they have a problem, identify root causes, and help them build problem-solving skills.
• Relapse Prevention: Observe behavioral changes, recognize craving triggers, and ensure the client cannot easily access the substance.
• Group Therapy and Counseling (CBT): Help the client manage difficult feelings, encourage assertiveness, identify relaxation techniques, and use leisure time constructively.
• Social Reintegration: Encourage support from family and friends. Encourage joining supportive groups like Narcotics Anonymous (NA).
• Vocational Rehabilitation: Train the client in skills/activities to keep them busy and earn a living.

• Legal Compliance (Lock and Key): Narcotics are strictly regulated by federal/national law. Maintain the drugs under double lock and key. The nurse must record the date, time, client's name, type, and amount of the drug used, and sign the entry in a narcotic inventory sheet.
• Wastage Protocols: If a narcotic drug must be wasted (partially used ampoule), the act must be witnessed by another qualified nurse, and the narcotic sheet must be signed by both the administering nurse and the witness. Computerized narcotic documentation systems should be utilized where available.
• Antidote Readiness: Always keep narcotic antagonists such as Naloxone readily available on the ward emergency trolley to treat respiratory depression.
• Pre-Administration Assessment:
  • Assess allergies or adverse effects from narcotics previously experienced by the client.
  • Assess for any respiratory disease (such as asthma or COPD) that might severely increase the risk of respiratory depression.
  • Assess the characteristics of pain and the effectiveness of previous pain medications.
  • Take and record baseline vital parameters (especially Respiratory Rate and SpO2) before administering the drug.
• Post-Administration Monitoring: Monitor vital signs, Level of Consciousness (L.O.C), pupillary response, bowel function (for severe constipation), urinary function (for retention), and the effectiveness of pain management.
• Alternative Therapies: Teach and apply non-invasive methods of pain management (e.g., positioning, ice/heat, distraction) in conjunction with narcotic analgesics to avoid narcotic overuse.
• Avoid Long-term Therapy: Work with physicians to taper narcotics early and avoid long-term therapy unless absolutely medically necessary (e.g., palliative care).

• Proper Medical Use: Reassure patients that the use of narcotics to treat severe, acute pain (under strict doctor supervision) is unlikely to cause addiction. Take drugs exactly as prescribed.
• Avoid CNS Depressants: Do not drink alcohol or take over-the-counter medications (like antihistamines or sleep aids) unless approved by the health care provider, as this causes fatal respiratory depression.
• Dietary Adjustments: Increase intake of fluids and fiber in the diet to prevent severe narcotic-induced constipation.
• Safety Precautions: The drugs often cause dizziness, drowsiness, and impaired thinking. Use extreme caution when driving, operating machinery, or making important decisions.
• Reporting Symptoms: Report decreasing effectiveness (tolerance) or the appearance of adverse side effects to the physician immediately. Do not self-increase the dose.
• Overdose Awareness: Teach family members the signs of the overdose triad (coma, slow breathing, pinpoint pupils) and, where available, how to administer take-home emergency Naloxone nasal sprays.
• Coping Mechanisms: Encourage the client to develop effective coping mechanisms for stress (e.g., exercise, talking to friends) rather than turning to substance use.
