(Portland, OR)  --  A proposal to legalize psychedelic mushrooms in Oregon is a step closer to making its way onto the November ballot.  Nearly 165-thousand people have signed Initiative Petition 34, a measure to allow people to use psilocybin in controlled doses and administered by state professionals.  If elections officials can verify enough valid signatures, I-P 34 will be voted on this fall.  Campaign leaders are confident but will know for sure by mid-July.  Oakland and Denver have decriminalized the substance but Oregon would be the first state to legalize it.
