CBD News Aggregator – One of the most hackneyed clichés about cannabis use—“stoner” memory failure—may be about to take a big hit. Researchers at University College London have discovered that a single dose of CBD increases blood flow to the part of the brain associated with memory function.

As reported in the Journal of Psychopharmacology in August, researchers found that 600 mg of oral CBD increased cerebral blood flow (CBF) to key regions of the brain involved in memory processing, particularly the hippocampus.

The team used a randomized, crossover, double-blind design in which 15 healthy, young adults with little or no history of cannabis use were given either CBD or a placebo. Using an MRI technique called arterial spin labelling, which measures changes in the blood oxygen levels, researchers showed significantly increased CBF in the hippocampus. Working memory function was assessed by asking test subjects to count forwards or backwards by random amounts, and episodic memory was tested with a prose recall task.
