Narcotics are highly addictive substances with a great potential for abuse and dependence. Tolerance to narcotics is established within two to three days of continued use. Cessation of narcotics results in withdrawal symptoms, which can perpetuate addiction due to unpleasant physical and psychological sensations.arcotics are used as analgesics for pain control, such as after oral surgery, for severe menstrual cramps, or for temporary pain relief in other outpatient surgical procedures. Intravenous narcotics are also used for palliative care in relieving pain of patients diagnosed with terminal cancer.
Bacteria or a virus can cause meningitis. Viral meningitis is more common, but bacterial meningitis is more serious. It can lead to brain damage, paralysis, or stroke. In some cases, it can be fatal. Many different types of bacteria can cause meningitis.
Bacterial meningitis may result in brain damage, hearing loss or a learning disability in 10% to 20% of survivors. A less common but even more severe (often fatal) form of meningococcal disease is meningococcal septicaemia, which is characterized by a haemorrhagic rash and rapid circulatory collapse.
