science: Study shows marijuana increases brain cell growth

By Juanita King, The Muse (Memorial University of Newfoundland)

ST. JOHNâ??S, Nfld â?? Supporters of marijuana may finally have an excuse to smoke weed every day. A recent study in the Journal of Clinical Investigation suggests that smoking pot can make the brain grow.

Though most drugs inhibit the growth of new brain cells, injections of a synthetic cannibinoid have had the opposite effect in mice in a study performed at the University of Saskatchewan. Research on how drugs affect the brain has been critical to addiction treatment, particularly research on the hippocampus.

The hippocampus is an area of the brain essential to memory formation. It is unusual because it grows new neurons over a personâ??s lifetime. Researchers believe these new cells help to improve memory and fight depression and mood disorders.

Many drugs -â?? heroin, cocaine, and the more common alcohol and nicotine â?? inhibit the growth of these new cells. It was thought that marijuana did the same thing, but this new research suggests otherwise.

Neuropsychiatrist Xia Zhang and a team of researchers study how marijuana-like drugs â?? known collectively as cannabinoids â?? act on the brain.

The team tested the effects of HU-210, a potent synthetic cannabinoid similar to a group of compounds found in marijuana. The synthetic version is about 100 times as powerful as THC, the high-inducing compound loved by recreational users.

The researchers found that rats treated with HU-210 on a regular basis showed neurogenesis â?? the growth of new brain cells in the hippocampus. A current hypothesis suggests depression may be triggered when the hippocampus grows insufficient numbers of new brain cells. If true, HU-210 could offer a treatment for such mood disorders by stimulating this growth.

Whether this is true for all cannabinoids remains unclear, as HU-210 is only one of many and the HU-210 in the study is highly purified.

â??That does not mean that general use in healthy people is beneficial,â?� said Memorial psychology professor William McKim. â??We need to learn if this happens in humans, whether this is useful in healthy people, and whether THC causes it as well.â?�

McKim warns that marijuana disrupts memory and cognition. â??These effects can be long-lasting after heavy use,â?� he said. â??This makes it difficult to succeed academically if you use it excessively.â?�

â??Occasional light use probably does not have very serious consequences. [But] there is some evidence that marijuana smoke might cause cancer.â?�

Still, the positive aspects of marijuana are becoming more plentiful as further research is done. McKim says itâ??s not surprising that THC and compounds like it could have medicinal effects.

â??Many have been identified,â?� he said. â??It stimulates appetite in people with AIDS, it is an analgesic, and blocks nausea in cancer patients undergoing chemotherapy. And it treats the symptoms of glaucoma.â?�

The research groupâ??s next studies will examine the more unpleasant side of the drug.

Sweet as

Nope, only 1 that reads a vast amount can gain the properties and knowledge of the text at hand.

Brains getting bigger? Isnt that like steroids for our brains? Damn the scientists just wont leave things alone, synthetic THC? Please, I dont want that. Just pass me a joint ^_^.

[dejayou30]

it doesn't mean you get smarter, it just means your brain gets bigger, so theoretically you could fit more stuff inside it. i'm sure you would still learn things at the same rate. i'm not sure if brains work like that but who knows. i love natural THC.

[senoirsalsa]

lol if only the feds beleived this, hell would freeze over

[dryst]

100x more potent than thc?!!!! gimmeh!!!!

[Gone]

Yeah, I don't think brain size will effect intelligence. We use a small portion of our brains as it is. Making it bigger will probably just increase the unused space.

[dryst]

how do we only use a small portion of our brain?...we use our entire brain dude...other wise whats the point of having it?

[Gone]

Well, I've always heard that humans only use a small portion of our brains. Could be a myth? I ain't no scientist.
