yes, if it help. Why not? Yes!! In British Columbia Canada there is a clinic that does give Marijuana to patients with diseases such as cancer and are taking Radiation, Chemo or both. It is suppose to help nausea and some pain levels. Some patients like it while others don't. It can be given in pill form (not as effective) but some patients who are non smokers refuse to smoke it. The Clinic is legal and gives documentation to the patient (and they must carry this documentation with them at all times) in case they are pulled over by the police. It says for "Medicinal purposes, etc." Yes, there are medicinal values to marijuana (THC), it helps with chronic pain, nausea, appetite stimulation, etc. It's prohibition is a political issue. There are many more dangerous and addictive drugs that are used daily by the medical community, such as opium derivatives. Marijuana can be psychologically addictive but not physically addictive. There are no known long term health problems other than short term memory loss. Some states and countries have decriminalized it's use, others are more conservative.
