The San Francisco Board of Supervisors has unanimously approved a measure to decriminalize psychedelics like psilocybin and ayahuasca, urging police to deprioritize their enforcement. The measure does not immediately change criminal justice policy but requests that city resources not be used for investigations or prosecutions related to the use of these substances. The decision is part of a growing trend of cities and countries reevaluating their stance on psychedelics, citing their potential therapeutic benefits. This move follows similar decriminalization efforts in other cities, including Denver, Oakland, and Santa Cruz.
