NBC News reports, “The drug "has been shown to reduce pain and nausea" in cancer patients. AIDS patients also use cannabis to eat, sleep and otherwise be more functional. Turns out that cannabidiol has none of the psychotropic effects of marijuana as a whole. The researchers hope to move to clinical trials on humans soon to test the cannabidiol inhibition of metastasis, reported in the San Francisco Chronicle. “What they found is that the cannabinoid turns off the overexpression of ID-1, which makes the cells lose their ability to travel to distant tissues. In other words, it keeps the cells more local and blocks their ability to metastasize. (spread to a new location) The researchers stressed cannabidiol works only on cancer cells that have these high levels of ID-1 and these do not include all cancerous tumors but, rather, aggressive, metastatic cells. But they've found such high levels in leukemia, colorectal, pancreatic, lung, ovarian, brain and other cancers.” http://www.msnbc.msn.com/id/49094732 http://www.sfgate.com/health/article/Pot-comp...875562.php
