Based on 120,000 answers of respondents – of whom 12,000 took psilocybin mushrooms in 2016 – this particular hallucinogen led to the least medical treatment, the Global Drug Survey 2017 found. Last year, just 0.2% of those who consumed psilocybin needed emergency medical treatment – a rate at least five times lower than that for MDMA, LSD and cocaine. According to the world’s biggest annual drug survey, 28,000 people said they had taken magic mushrooms at some point in their lives, with 81.7% seeking a moderate psychedelic experience and the enhancement of environment and social interactions.
