Susanne Sorensen, MD, head of research at the Alzheimer's Society, stated in a Feb. 22, 2005 BBC News article titled "Marijuana May Block Alzheimer's":

“The Alzheimer’s Society looks forward to seeing further research being carried out on cannabinoid receptors as drug targets for Alzheimer’s disease but would warn the public against taking marijuana as a way of preventing Alzheimer’s.

It is now generally recognized that as well as providing a ‘high,’ long-term use of marijuana can also lead to depression in many individuals.”
