Addicted and losing your job because of psilocybin? I've not tried it myself, but many of my friends have, and anecdotally, none of them have (to my knowledge) ever even gotten to the point of it being a "habit".
I can't say the same for alcohol, cocaine, and even cannabis. I know people who have had problems with all of them.
Even Terence McKenna, who himself was likely part mushroom given how many he ingested, said time and time again that mushrooms are resistant to abuse. If you take a very high dose, the experience itself can be so difficult and wonderful, that the idea of doing that to yourself again starts to seem ridiculous. :)
