High-dose cannabis stimulates growth of brain cells in rats
Cannabis, the third most popular recreational drug after alcohol and tobacco, yesterday won an unlikely accolade from scientists who said that it could boost brain power. Experiments on rats given a potent cannabinoid have shown the drug stimulates the growth of new brain cells. Canadian researchers found that the drug caused neurons to regenerate in the hippocampus, an area that controls mood and emotions, after one month of treatment. Its effect was similar to that of the antidepressant drug Prozac, which also stimulates nerve growth in the hippocampus. The rats were less anxious and more willing to eat in a novel environment that would normally make them fearful.
