Study: Marijuana helps to fight cancer

Researchers in Spain have found out that the main chemical in marijuana appears to be helpful in the destruction of brain cancer cells. 

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, according to a new study released on Thursday. 

The authors from the Complutense University in Madrid conducted the study with scientists from other universities, AFP reported. 

The research indicates that THC and related "cannabinoids" appear to be "a new family of potential antitumoral agent." 

The authors wrote that the chemical may prove useful in the development of future "antitumoral agents." 

The scientists conducted their research on mice, first stimulating the growth of cancer in the lab animals, then injecting them with a daily dose of THC near the site of their tumors. 

The researchers also analyzed the tumors of two patients in an experimental trial looking at the effects of THC on a highly aggressive form of brain tumor, and saw findings "in line with the preclinical evidence" first observed in the laboratory mice.
