Aangezien iemand het argument opwierp dat cannabis meer kankerverwekkende stoffen zou bevatten, nog even dit:

The largest study of its kind has unexpectedly concluded that smoking marijuana, even regularly and heavily, does not lead to lung cancer.

The new findings "were against our expectations," said Donald Tashkin of the University of California at Los Angeles, a pulmonologist who has studied marijuana for 30 years.

"We hypothesized that there would be a positive association between marijuana use and lung cancer, and that the association would be more positive with heavier use," he said. "What we found instead was no association at all, and even a suggestion of some protective effect."

The International Journal of Oncology published a study last year, for example, indicating that cannabinoids successfully kill cancer cells, and the benefits increase when combined with chemotherapy. An early preclinical study we recently conducted also found that cancer cells derived from patient blood samples were differentially sensitive to the two main active compounds in cannabis—tetrahydrocannabinol (THC) and tetrahydrocannabinolic acid (THCA).

A number of other laboratory and animal studies have been conducted in recent years on colon, breast and brain cancers. They indicate that cannabinoids may inhibit tumor growth by blocking cell growth, causing cell death and blocking the development of blood vessels that tumors require to grow. We have yet to make the leap to study these promising effects on humans.
