A new study from the University of Illinois at Urbana-Champaign found that over 8 million people in the US, approximately 2.8% of the population, reported using psilocybin in the past year. Psilocybin users were more likely to be white, male, and affluent compared to nonusers, and often used other mind-altering substances.
A new study links even low levels of alcohol consumption to increased risks of death, disability, and chronic diseases like cancer and heart disease.
