Medical Marijuana: Whole Plant Better Than Isolated Components in Pain Relief, Italian Study Finds
from Drug War Chronicle, Issue #544, 7/25/08
Scientists at the University of Milan have published a study finding that whole-plant marijuana extracts provide better relief for neuropathic pain than isolated components of the plant, like THC alone. The research is an intervention in the ongoing debate between medical marijuana supporters and herbal and alternative medicine advocates on one side and the US government, some politicians, and the pharmaceuticalized medicine industry on the other.

"The use of a standardized extract of Cannabis sativa... evoked a total relief of thermal hyperalgesia, in an experimental model of neuropathic pain,... ameliorating the effect of single cannabinoids," the investigators reported. "Collectively, these findings strongly support the idea that the combination of cannabinoid and non-cannabinoid compounds, as present in extracts, provide significant advantages... compared with pure cannabinoids alone." Congressional drug warriors like Rep. Mark Souder (R-IN) have long argued that marijuana is not a medicine and that any medicinal compounds in the plant should be isolated or synthesized, as is the case with Marinol, which contains one of the hundreds of cannabinoids found in the plant. The DEA takes a similar approach.
But this latest research only adds to the evidence that that position is mistaken.
