Fibromyalgia, a chronic pain syndrome, is hard to treat

trying medical marijuana to ease their discomfort.
Still widely controversial, "medical marijuana" refers to the smoked form of
the drug. It does not refer to the synthesized version of THC, one of the
active chemicals in marijuana, that's available in a medication called Marinol.

oncologist and director of clinical research programs at the Osher Center for
Integrative Medicine at the UCSF School of Medicine in San Francisco, is one of

Marijuana -- the plant's Latin name is cannabis -- has a host of
components called cannabinoids. These components may have medicinal
