Inhaling cannabidiol e-liquid has positive effects on the verbal episodic memory of young healthy people. This was recently found by a group of Swiss researchers in a placebo-controlled study. Thirty-four people with an average age of 22 and no previous illnesses were asked to memorize 15 unrelated nouns. They were then given a single dose of CBD (12.5 mg cannabidiol e-liquid) once and once a placebo to vaporize. After about 20 minutes, they were assessed on their verbal episodic memory.

CBD outperforms placebo

The result is clear: compared to the placebo, CBD improved the short-term memory performance. The Basel research group concludes that not only does CBD have no negative effect on basic cognitive functions, they also see further evidence of the interaction of the central endocannabinoid system with vaporized CBD. In conclusion, CBD may be able to positively influence memory processes and may have further therapeutic potential if appropriate.

To investigate optimal dose-response relationships, the neuroscientists from Switzerland recommend further extensive studies.
