According to new research from the Institute of Psychiatry, Psychology & Neuroscience (IoPPN) at King's College London, no, it can’t.
The study, published in Neuropsychopharmacology examined whether marijuana with higher levels of CBD can protect consumers from psychotic experiences and memory problems, reported Medical Express.
