Top Documentary Films: The Medical Marijuana Revolution
Marijuana is also known as pot, grass and weed but its formal name is actually cannabis. It comes from the leaves and flowers of the plant Cannabis sativa. It is considered an illegal substance in the US and many countries and possession of marijuana is a crime punishable by law. The FDA classifies marijuana as Schedule I, substances which have a very high potential for abuse and have no proven medical use. Over the years several studies claim that some substances found in marijuana have medicinal use, especially in terminal diseases such as cancer and AIDS. This started a fierce debate over the pros and cons of the use of medical marijuana. To settle this debate, the Institute of Medicine published the famous 1999 IOM report entitled Marijuana and Medicine: Assessing the Science Base. The report was comprehensive but did not give a clear cut yes or no answer. The opposite camps of the medical marijuana issue often cite part of the report in their advocacy arguments. However, although the report clarified many things, it never settled the controversy once and for all.
Let’s look at the issues that support why medical marijuana should be legalized.
(1) Marijuana is a naturally occurring herb and has been used from South America to Asia as an herbal medicine for millennia. In this day and age when the all natural and organic are important health buzzwords, a naturally occurring herb like marijuana might be more appealing to and safer for consumers than synthetic drugs.
(2) Marijuana has strong therapeutic potential. Several studies, as summarized in the IOM report, have observed that cannabis can be used as analgesic, e.g. to treat pain. A few studies showed that THC, a marijuana component is effective in treating chronic pain experienced by cancer patients. However, studies on acute pain such as those experienced during surgery and trauma have inconclusive reports. A few studies, also summarized in the IOM report, have demonstrated that some marijuana components have antiemetic properties and are, therefore, effective against nausea and vomiting, which are common side effects of cancer chemotherapy and radiation therapy. Some researchers are convinced that cannabis has some therapeutic potential against neurological diseases such as multiple sclerosis. Specific compounds extracted from marijuana have strong therapeutic potential. Cannobidiol (CBD), a major component of marijuana, has been shown to have antipsychotic, anticancer and antioxidant properties. Other cannabinoids have been shown to prevent high intraocular pressure (IOP), a major risk factor for glaucoma. Drugs that contain active ingredients present in marijuana but have been synthetically produced in the laboratory have been approved by the US FDA. One example is Marinol, an antiemetic agent indicated for nausea and vomiting associated with cancer chemotherapy. Its active ingredient is dronabinol, a synthetic delta-9- tetrahydrocannabinol (THC).
