    A new study conducted by scientists at Complutense University in Spain suggests that cannabis extracts may shrink brain tumours and other cancers by blocking the growth of the blood vessels which feed them.
    According to New Scientist, Manuel Guzman and colleagues have demonstrated how the cannabis extracts block a key chemical needed for tumours to sprout blood vessels.
    The team tested the effects of marijuana extract, delta-9-tetrahydrocannabinol in 30 mice and found that it inhibited the expression of several genes related to the production of a chemical called vascular endothelial growth factor (VEGF).
    VEGF is critical for angiogenesis, which allows tumours to grow a network of blood vessels to supply their growth. The cannabinoid significantly lowered the activity of VEGF in the mice and two human brain cancer patients, the study showed.
    According to teammember, Cristina Blazquez, "We saw that the tumours [in mice] were smaller and a bit pallid. The paleness of the cancer reflected its lack of blood supply as a result of the treatment. In the human patients, she says: "It seems that it works, but it's very early."

    No Link Between Pot Smoking, Cancer
    Marijuana smoke contains THC, which may inhibit cancer, an expert says

    WEDNESDAY, Oct. 19 (HealthDay News) -- Even though they're chemically similar, marijuana smoke is less likely than tobacco smoke to cause cancer, according to one expert review of the literature.

    The review, by Dr. Robert Melamede of the University of Colorado, Colorado Springs, noted that tobacco and marijuana smoke differ in a number of ways, particularly in the fact that marijuana smoke contains tetrahydrocannabinol (THC) , while tobacco smoke contains nicotine. Nicotine increases the cancer-promoting effects of smoke, while THC reduces those effects, he explained.

    And even though THC and nicotine act on related cellular pathways, they bind to different receptors to activate these pathways, the review found. Cells in the lungs and respiratory passages are lined with nicotine receptors but these cells don't appear to have THC receptors. This may explain why smoking marijuana has so far not been linked with lung cancer, a major cause of death from cigarette smoking.

    Research has also shown that marijuana kills cancer cells and reduces tumor growth. This is, in part, because marijuana reduces the formation of blood vessels that nourish tumors.

    However, the review warned that the effects of marijuana are complex and sometimes contradictory. It also noted that many people use marijuana and tobacco together, and the two drugs may interact in complex ways.

    While some governments are reluctant to approve marijuana for medicinal use, the review noted that there's increasing evidence that marijuana can improve the lives of patients with a broad range of health problems, including insomnia, AIDS, multiple sclerosis and Alzheimer's disease.

    The review will be published in an upcoming issue of the journal Harm Reduction.

    What have I been saying? xD
    I think this presents a valid argument for the legalization of marijuana, besides it's use as a treatment. Concidering the incredable rate of cancer today the legalization of marijuana when it, as you said, helps reverse the effects of cancer would decrease the general rate of cancer as well.
