Lester Grinspoon, MD, Emeritus Professor of Psychiatry at Harvard Medical School, wrote in a Mar. 1, 2007 editorial in the Boston Globe titled "Marijuana as Wonder Drug":

“The mountain of accumulated anecdotal evidence that pointed the way to the present [marijuana as treatment for HIV neuropathic pain] and other clinical studies also strongly suggests there are a number of other devastating disorders and symptoms for which marijuana has been used for centuries; they deserve the same kind of careful, methodologically sound research.

While few such studies have so far been completed, all have lent weight to what medicine already knew but had largely forgotten or ignored: Marijuana is effective at relieving nausea and vomiting, spasticity, appetite loss, certain types of pain, and other debilitating symptoms. And it is extraordinarily safe — safer than most medicines prescribed every day. If marijuana were a new discovery rather than a well-known substance carrying cultural and political baggage, it would be hailed as a wonder drug.”
