Although marijuana is now considered a form of treatment for medicinal purposes, it still merits a lot of research when it comes to discussing its effects. Smoking marijuana daily not only damages the cells in the bronchial passage but it also decreases the ability of immune cells present in the lungs. An individual is rendered weak and unable to fight off fungi, bacteria and tumor cells. For patients with existing low immunity levels, this could result in an increase in the possibility of dangerous pulmonary infections. Patients who suffer with pre-existing immune deficits resulting from AIDS, organ transplants or chemotherapy can also be administered medicinal marijuana. However the dosage should be infrequently and as minimum as possible so that it does not accelerate or aggravate the disorders.
Effects of marijuana include triggering of bi-polar psychosis, paranoia, delusions, depersonalization, hallucinations, flashbacks, panic attacks and schizophrenia. Doctors who administer medicinal marijuana to the terminally ill and mental illness patients should exercise severe restraint. They also need to tread with caution while prescribing the dosage to such patients. Unsupervised and intensive usage of medicinal marijuana also has adverse effects on coordination, perception and judgment. This could in turn lead to many falls, injuries and accidents.
