Marijuana Compound Spurs Brain Cell Growth

THURSDAY, Oct. 13 (HealthDay News) -- When it comes to the controversy surrounding medical marijuana, an international team of researchers is busy stirring the pot by releasing findings that suggest the drug helps promote brain cell growth while treating mood disorders.
According to the study in rats, a super-potent synthetic version of the cannabinoid compound found in marijuana can reduce depression and anxiety when taken over an extended period of time.
This mood boost seems to be the result of the drug's ability to promote the growth of new brain cells, something no other addictive drug appears able to do, the researchers say.
The findings, which appear in the November issue of the Journal of Clinical Investigation, remain preliminary, however.
"Our results were obtained from rats, and there's a big difference between rats and humans," said study co-author Dr. Xia Zhang, of the neuropsychiatry research unit in the department of psychiatry at the University of Saskatchewan in Saskatoon, Canada. "So, I don't really don't know yet if our findings apply to humans. But our results indicate that the clinical use of marijuana could make people feel better by helping control anxiety and depression."
The new findings come on the heels of a U.S. Supreme Court ruling in June granting federal authorities the power to stop doctors from prescribing marijuana. That decision also bars individuals from cultivating the herb for medical purposes.
The decision overrides laws currently on the books in 11 states which had legalized the use of marijuana for patients receiving a doctor's approval. According to the ruling, the Supreme Court justices made their decision on the basis of interstate commerce regulations rather than on an evaluation of the pros and cons of medical marijuana use.
But does medical marijuana work? To help settle that question, Zhang's team focused on the potential of a synthetic laboratory-produced form of the cannabinoid compound naturally found in the marijuana plant.
Humans and other animals also naturally produce the compound, and are known to have cannabinoid receptors lying on the surface of cells in the nervous system and the immune system.
