High-Potency Cannabis Linked to Youth Psychosis

Young individuals who use high-potency cannabis between ages 16 and 18 are twice as likely to experience psychosis by their mid-twenties compared to those who use lower-potency strains. This research utilized data from the Children of the 90s study, tracking thousands of participants from Bristol.

Exercise Warps Time Perception

People perceive time as moving slower when they are exercising compared to resting or post-exercise. The research involved participants undergoing a time perception task during different cycling conditions, including solo and competitive scenarios.
