Ultralow doses of THC found to protect the brain
A study published in July 2014 by The Adelson Center for the Biology of Addictive Diseases and The Mauerberger Chair in Neuropharmacology, Sackler Faculty of Medicine, Tel-Aviv University, Tel-Aviv, Israel found that doses of THC low enough to not cause psychotropic activity were enough to protect mice brains from long term damage. In this study, mice were treated with a chemical that causes inflammation in the brain (lipopolysccharide, or “LPS”). Mice that received a single ultralow dose of THC either 48 hours before the LPS treatment or 1-7 days after LPS treatment, and given an object recognition test a few weeks later. LPS causes long-lasting cognitive damage, but the mice who had been treated with THC did not show that damage. Read the full study here.
