Treatment against cancers


The research team of the Complutense University discovered that cannabinoids such as THC had anticancer effects in mice with human brain tumors. When mice with human brain cancer cells received THC, the tumor shrank. Using electron microscopes to analyze brain tissues 30 days before and after THC treatment, the researchers found that THC eliminated cancer cells, leaving healthy cells intact. The patients didn't have any toxic effects from the treatment. However, the mechanisms of THC on tumor cell-killing action are still vague.



One of the most important research has been the finding that smocking cannabis does not increase the risk of developing lung cancer or chronic obstructive pulmonary disease (COPD) among people who don't smoke tobacco, and may indeed confer a protective effect. Beginning in 2001, multiple research teams began to report results showing that smoking cannabis does not, by itself, increase the risk of lung cancer, and this result is now well-established. Many studies reported a strongly synergistic effect between tobacco use and smoking cannabis such that tobacco smokers who also smocked cannabis dramatically increased their risk of developing lung cancer or chronic obstructive pulmonary disease.

Researchers from the University of British Columbia presented a study at the American Thoracic Society in 2007 showing that smoking marijuana and tobacco together more than tripled the risk of developing COPD than just smoking marijuana. Similar findings were observed in April 2009 by the Vancouver Burden of Obstructive Lung Disease Research Group. The study reported that smoking both tobacco and marijuana synergistically increased the risk of respiratory symptoms of COPD.

Tetrahydrocannabinol has been found to reduce tumor growth in common lung cancer by 50% and to slow down the spreading of the cancer say researchers at Harvard University, who tested the chemical in laboratory studies and also in mice studies. The researchers insist and say that THC should be used to treat lung cancer.
