Scientists said on Tuesday psilocybin, the psychedelic compound in magic mushrooms, may one day be an effective treatment for patients with severe depression who fail to recover using other therapies. British researchers said a small-scale pilot study of psilocybin's use in cases of treatment-resistant depression showed it was safe and effective. Of 12 patients given the drug, all showed some decrease in symptoms of depression for at least three weeks. Seven continued to show a positive response at three months.
