Previously, the researchers behind the study – from the Norwegian University of Science and Technology in Trondheim – had conducted a population study investigating associations between mental healthand psychedelic use. However, that study, which looked at data from 2001-04, was unable to find a link between use of these drugs and mental health problems.
“Over 30 million US adults have tried psychedelics and there just is not much evidence of health problems,” says author and clinical psychologist Pål-Ørjan Johansen.
“Drug experts consistently rank LSD and psilocybin mushrooms as much less harmful to the individual user and to society compared to alcohol and other controlled substances,” concurs co-author and neuroscientist Teri Krebs.
For their study, they analyzed a data set from the US National Health Survey (2008-2011) consisting of 135,095 randomly selected adults from the US, including 19,299 users of psychedelic drugs.
