In the US, most psychedelics are federally illegal to possess or use. However, some states and cities have passed laws allowing certain psychedelics in specific contexts, like Oregon's Psilocybin Services Act and Colorado's Natural Medicine Health Act.
The professionals on Maria's List focus mainly on education, preparation, and integration support for psychedelics. They can't legally provide psychedelic experiences, except for licensed medical professionals offering ketamine-assisted therapy and licensed facilitators operating within state-regulated programs.
Always check your local laws, consult a healthcare provider before using psychedelics, and don't ask the professionals here to sell you controlled substances.
