I've done shrooms couple of times, it was profoundly mind-and-life-changing experience and in many ways the most intense and beautiful event in my life. But I wouldn't recommend it to maybe 1/3 to 1/2 of people I know, simply because I wouldn't be sure it wouldn't mess them up badly, like really badly. At least not under professional supervision and adequate gradual dosing.
You make everybody smoke weed few times, not much bad can happen. You make everybody trippin', and consequences are unpredictable. Show some respect for the stuff, it very well deserves it.
