   Experts have shown that when certain parts of cannabis are used to treat   
   cancer tumours alongside radio therapy treatment the growths can virtually   
   disappear.   
      
      
      
   Experts have shown that when certain parts of cannabis are used to treat   
   cancer tumours alongside radio therapy treatment the growths can virtually   
   disappear.   
   The new research by specialists at St George's, University of London, studied   
   the treatment of brain cancer tumours in the laboratory and discovered that   
   the most effective treatment was to combine active chemical components of the   
   cannabis plant which    
   are called cannabinoids.   
      
   Two of these called tetrahydrocannabinol (THC) and cannabidiol (CBD) were   
   tested as part of the research into brain cancer which is particularly   
   difficult to treat and claims the lives of about 5,200 each year. It also has   
   a particularly poor prognosis    
   as the rate of survival after five years of patients' diagnosis is around 10%.   
      
   Cannabinoids are the active chemicals in cannabis and are also known more   
   specifically as phytocannabinoids. There are 85 known cannabinoids in the   
   cannabis plant.   
   The new research is the first to show a drastic effect when combining THC and   
   CBD with irradiation. Tumours growing in the brains of mice were drastically   
   slowed down when THC/CBD was used with irradiation.   
      
   Dr Wai Liu, Senior Research Fellow and lead researcher on the project, said:   
   "The results are extremely exciting. The tumours were treated in a variety of   
   ways, either with no treatment, the cannabinoids alone, and irradiation alone   
   or with both the    
   cannabinoids and irradiation at the same time.   
      
   "Those treated with both irradiation and the cannabinoids saw the most   
   beneficial results and a drastic reduction in size. In some cases, the tumours   
   effectively disappeared in the animals. This augurs well for further research   
   in humans in the future.    
   At the moment this is a mostly fatal disease.   
      
   "The benefits of the cannabis plant elements were known before but the drastic   
   reduction of brain cancers if used with irradiation is something new and may   
   well prove promising for patients who are in gravely serious situations with   
   such cancers in the    
   future."   
      
   The research team are discussing the possibility of combining cannabinoids   
   with irradiation in a human clinical trial.   
      
   The research has been published in the Molecular Cancer Therapeutics journal.   
   Cannabinoids are the active chemicals in cannabis and are also known more   
   specifically as phytocannabinoids. There are 85 known cannabinoids in the   
   cannabis plant. The primary psychoactive component of cannabis is called   
   tetrahydrocannabinol (THC).
