Journal Article

Schizotypy but not Cannabis Use Modestly Predicts Psychotogenic Experiences: A Cross-Sectional Study Using the Oxford-Liverpool Inventory of Feelings and Experiences (O-LIFE). Journal of Addiction, 2020, Article 5961275. https://doi.org/10.1155/2020/5961275

Objective. Cannabis use predicts psychosis in longitudinal studies, but it is difficult to infer causation. Some precursor variables predict both, including childhood trauma and adversity. Additionally, some of the desired effects of cannabis use res...

Four relevant theoretical issues are reviewed: (i) t... Read More about How to measure mood in nutrition research.

Ingesting foods or drugs can alter rated mood. Moods have been theorised as reinforcers that cause ingestion. This assumption may be incompatible with the current two-system models of affect, where 'moods' are less intense yet more protracted than em...

The effects of carbohydrates on arousal (1999)
Journal Article
