THC may help fight lung cancer

BOSTON - An American study says the active substance in marijuana may help fight lung cancer. The Harvard researcher Anju Preet says lab and mouse studies show the compound THC cut lung tumor growth in half and helped prevent the cancer from spreading.

Preet said THC boots the natural anti-inflammatory properties of two specific endocannabinoids present in high amounts on lung cancer cells.

THC was injected into mice that had been implanted with human lung cancer cells. Tumors shrank by about 50 percent in three weeks, compared with tumors in untreated mice, the report said.

The report, presented at the annual meeting of the American Association for Cancer Research, says other research suggests THC could also help fight brain, prostate and skin cancers.
