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.
Introduction. Meningitis results from the inflammation of the meninges (the thin membranes surrounding the brain and spinal cord). It is usually caused by a viral or bacterial infection. Most cases of meningitis are viral, but it can be hard to pinpoint without invasive testing.iral meningitis usually clears up on its own and does not cause any permanent damage. Bacterial meningitis can cause brain damage, learning disabilities, hearing loss, or even death without treatment for the specific type of bacteria.
