Honestly even if I happened to eat a mildly poisonous shroom which never happened it would be fine for me personally. There is huge amount of edible mushrooms but we stick to few select safe ones that are hard to mistake.

I have done much worse things to my body with drugs and alcohol poisoning every other day. One instance of light poisoning per year or something like that would be like nothing. Not that it ever happened because I stick to the rules my parents teached me and their parents teached them and so on.

I wouldn’t dare to pick mushrooms abroad though
