[narrator] But according to this study,
that risk appears to be very low. It surveyed nearly 20,000
psychedelics users and found no significant associations
between these drugs and mental health problems. In fact, lifetime psychedelic use was associated with a lower likelihood of past year inpatient
mental health treatment. But none of that new research
changed the law. Now, 184 countries have signed on
to the UN’s psychedelics ban. Although religious ceremonies sometimes
get a special exemption in national laws. And in 2016, Americans thought trying LSD was as dangerous as having four
or five drinks nearly every day. When we initially sought approval
of our first psilocybin study, such a study hadn't been approved
in almost 30 years
