But the rise of psychedelic use has brought about promise for those struggling with mental health problems, and their families. No other medication can induce psychological and neurobiological changes the way psychedelics can, thereby improving cognitive function and emotional processing. Psychedelics activate serotonin receptors, enhance neuroplasticity, and disrupt the default mode networks that cause rigid thinking and worsen depression. Because of this, psychedelics are considered a revolutionary treatment for severe mental health conditions that are resistant to treatment.
