Magic Mushrooms

Hi all, I just want to ask if someone ever tried using shrooms or truffles for medical purposes? I was reading some articles about this magic truffles and shrooms before engaging my self for the first time. Like this one from www.trufflemagic.com/blog/psilocybe-cyanescens/ .They say that it has a very potent effect on the brain and hallucination. Unlike marijuana does it have any medical use? In one article that I've read magic truffles or shrooms compaired to synthetic drugs are very alarming. Also magic mushroom are use on reducing the symptoms of depression, obsessive-compulsive disorder and anxiety. It can also help people to quit smoking and alcohol addiction. Some studies also suggest the property of magic shrooms/truffles can be useful for cancer patients. I would really want to hear other insights regarding this new possible alternative meds. Thanks
