If passed, the measure would reduce criminal penalties for the manufacture, delivery and possession of psilocybin, which is the hallucinogen contained in psychedelic mushrooms, OPB reported.

In a tweet, members of the Oregon Psilocybin Society said it will begin gathering the 140,000 signatures required to put the measure on the ballot for the 2020 election.

On its website, society members asserted there is more evidence now that the drug is safe and can be used in treatment for depression, anxiety, PTSD and even drug addiction.

The federal government controlled use of mushrooms during the 1970s, OPB reported.
