Study: High-Potency Cannabis & Concentrates Impair Memory, Not Decision-Making
A recent study conducted at Washington State University has shed light on the effects of high-potency cannabis and cannabis concentrates on cognitive functions. The research, one of the few to investigate these substances, involved 80 participants who were divided into four groups and observed via Zoom in their own homes.
Participants, who bought their own cannabis products and were compensated with Amazon gift cards, were divided into groups using cannabis flower with or without CBD, concentrates with CBD, and a sober control group. The study found no significant impact on decision-making tests compared to the sober group.
Vaping high-potency concentrates was found to have similar effects on memory as smoking less potent cannabis flower. However, all cannabis-using groups performed poorly on a false memory test. Specifically, cannabis flower with CBD impaired verbal free recall, while cannabis without CBD and concentrates impaired source memory. Some memory impairments were also found in free recall and false memories.
This study, conducted under relaxed federal restrictions that previously limited researchers to studying low-potency cannabis, provides valuable insights into the effects of high-potency cannabis and cannabis concentrates on memory. Further research is needed to fully understand these effects and their implications.
