Washington DC on Tuesday night seemed poised to pass a ballot measure that would effectively decriminalize the use of magic mushrooms and other psychedelic plants.

By around 10:30 p.m. Initiative 81 had a commanding lead, with about 76.59 percent voting to pass the measure, according to local outlets.

The initiative would make the non-commercial cultivation, distribution, possession and use of psilocybin and similar drugs the police department’s lowest enforcement priority.

It would not make commercial sales of the psychedelics legal.

Meanwhile Oregon could become the first state to legalize mushrooms, as voters consider Measure 109, which asks whether to allow the regulated medical use of psilocybin.

Supporters point to evidence that the chemical could have positive effects for patients with mental health issues.
