La marihuana cura el cáncer ¿?

De la boca de Project Censored me llega un reportaje sobre un estudio médico español que reza "la marihuana (THC) cura el cáncer"... ¿Será cierto? Les muestro un extracto:

A Spanish medical team’s study released in Madrid in February 2000 has shown that tetrahydrocannabinol (THC), the active chemical in marijuana, destroys tumors in lab rats. These findings, however, are not news to the U.S. government. A study in Virginia in 1974 yielded similar results but was suppressed by the DEA, and in 1983 the Reagan/Bush administration tried to persuade U.S. universities and researchers to destroy all cannabis research work done between 1966 and 1976, including compendiums in libraries.

The research was conducted by a medical team led by Dr. Manuel Guzman of Complutence University in Madrid. In the study, brains of 45 lab rats were injected with a cancer cell, which produced tumors. On the twelfth day of the experiment, 15 of the rats were injected with THC and 15 with Win-55, 212-2, a synthetic compound similar to THC. The untreated rats died 12-18 days after the development of the tumors. THC treated rats lived significantly longer than the control group. Although three were unaffected by the THC, nine lived 19-35 days, while tumors were completely eradicated in three others. The rats treated with Win-55,212-2 showed similar results.

El articulo completo está en esta página. Yo no sé si el THC cure el cáncer, pero lo que sí sé es que se sabe, ya por décadas, que el THC alivia los dolores de los pacientes cancerosos, especialmente el breakthrough pain que es incontrolable con morfina y otras medicinas para el dolor.
