Are there any long term effects from the use of psilocybin (psychadelic mushrooms)?

I've been researching a lot about psycadelic drugs lately (mostly from watching the Doors movie so much). I was wondering if there are any long term effects from taking shrooms because all i've read--even in the government scary dont use drugs stuff--are the physical effects while your on the drug. Does it stay in your spine like LSD? Are there chances of flashbacks? I've heard you can have a flashback but only up to a year after you've used it.

[i'm not trying to find out because i want to do them, i'm just curious. and i want to be able to dispel all my friends claims that there's nothing wrong with them]

Yes, I should have cleaned the cow s hit off before eating them though.
