The evidence is becoming overwhelming that marijuana fights cancer. See below for a few more blockquotes on this topic but first, from AFP:
The main chemical in marijuana appears to aid in the destruction of brain cancer cells, offering hope for future anti-cancer therapies, researchers in Spain wrote in a study released Thursday.
The authors from the Complutense University in Madrid, working with scientists from other universities, found that the active component of marijuana, tetrahydrocannabinol (THC), causes cancer cells to undergo a process called autophagy -- the breakdown that occurs when the cell essentially self-digests.
The research, which appears in the April edition of US-published Journal of Clinical Investigation, demonstrates that THC and related "cannabinoids" appear to be "a new family of potential antitumoral agent."
ScienceDaily (Oct. 19, 2005) — Cannabis smoke is not as carcinogenic as tobacco smoke. In a review article published today in Harm Reduction Journal, Dr. Melamede from the University of Colorado, Colorado Springs, USA, writes that although cannabis smoke and tobacco smoke are chemically very similar, evidence suggests that their effects are very different and that cannabis smoke is less carcinogenic than tobacco smoke.
The pharmacological effects of tobacco and cannabis smoke differ in many ways, mainly because tobacco smoke contains nicotine while cannabis smoke contains tetrahydrocannabinol (THC). The cancer-promoting effects of smoke are increased by nicotine, while they are reduced by THC.
ScienceDaily (Apr. 17, 2007) - The active ingredient in marijuana cuts tumor growth in common lung cancer in half and significantly reduces the ability of the cancer to spread, say researchers at Harvard University who tested the chemical in both lab and mouse studies.
They say this is the first set of experiments to show that the compound, Delta-tetrahydrocannabinol (THC), inhibits EGF-induced growth and migration in epidermal growth factor receptor (EGFR) expressing non-small cell lung cancer cell lines. Lung cancers that over-express EGFR are usually highly aggressive and resistant to chemotherapy.
Cannabis may be bad for the lungs, but the active ingredient in marijuana may help combat lung cancer, new research suggests.
In lab and mouse studies, the compound, known as THC, cut lung tumor growth in half and helped prevent the cancer from spreading, says Anju Preet, PhD, a Harvard University researcher in Boston who tested the chemical.
While a lot more work needs to be done, the results suggest THC has therapeutic potential, she tells WebMD.
Moreover, other early research suggests the cannabis compound could help fight brain, prostate, and skin cancers as well, Preet says.
