Speed, synthetic cannabis, and alcohol top the list for the most dangerous drugs in the 2017 Global Drug Survey, while cannabis and magic mushrooms are the safest. The results are based on the percentage of people who sought emergency medical treatment after taking one of the drugs.
From The Guardian:
Both [Adam] Winstock [a consultant addiction psychiatrist and founder of the Global Drug Survey] and [Brad] Burge [from the Multidisciplinary Association for Psychedelic Studies (Maps)] said that the findings indicate a need for drug policy reform, with a focus on shifting psychedelics off the schedule one list of the most dangerous controlled substances.
“Drug laws need to balance the positives and problems they can create in society and well crafted laws should nudge people to find the right balance for themselves,” said Winstock.
“People don’t tend to abuse psychedelics, they don’t get dependent, they don’t rot every organ from head to toe, and many would cite their impact upon their life as profound and positive. But you need to know how to use them.”
