Marijuana as medicine-overview of the topic

Marijuana is a drug made from the dried leaves and the flowering tops of the plant. People usually smoke it as in cigarettes or pipes and can be added in food and drinks. When smoked marijuana produces chemicals that have immediate or short term effects. Studies have shown that regular users of marijuana can develop serious health problems such as: short term memory, coughing, chest pain, reduced fertility, cancer, lung cancer- smoke contains cancer causing substance.

Cannabis has been used for thousands of years in medicine mainly as anti-inflammatory, pain killer and antidepressant. Marijuana is known to have negative effects on human body, there is intense debate about the use of marijuana for medical treatments.
Today, many believe that marijuana should be legalized for medical use as its use can relieve nausea, vomiting and loss of appetite in patients with cancer and Aids, while others believe that marijuanas's negative effects outweigh its benefits.
Although there is some research evidence about cannabis usefulness to alleviate pain in some patients,  further research is needed to examine the benefits of cannabis for these illnesses.

There is evidence to suggest that people who use marijuana on regular basis may become depended on it. However many other drugs that are prescribed to patients are even greater risks for addiction, and if patients are chronically ill this risk is worth taking for pain relief.
