A recent University of BC study, carried out on mice which had been bred to have genetic mutation for the Alzheimer’s, reveled that marijuana seems to have no role to play whatsoever in improvement of memory or reversing the effects of the condition.

"We are a little surprised actually. Originally, we were hoping there would be a positive effect, based on previous research", said Dr. Weihong Song, the Canada Research Chair in Alzheimer's disease and a UBC Psychiatry Professor.

As per the researchers, the recent experiments were meant to actually validate a research which went back about 6 years, suggesting that marijuana might end up protecting brain cells from injurious inflammations, which are a result of the disease, and might even promote regeneration of neurons.

The study was carried out on a total of 100 mice, and conclusions were reached at after extensive analysis of the data collected throughout the process.

The researchers were funded by the Canadian Institutes of Health Research, the Jack Brown and Family Alzheimer's Research Foundation and the Michael Smith Foundation for Health Research.
