Eat the eighth. Don't waste your first shroom trip on a tiny dose...your first trip is always the best. I always hear friends talking about how they wished they had taken more their first time.

Personally, I ate 4grams and redosed 3 more grams 2-3 hours later. It was only my second time to be 'unsober' and it was the coolest trip I've ever taken. No regrets...especially since they were free.

I wouldn't reccomend eating a quarter...my situation was very perfect and pretty much risk free. Good friends, no responsibilities, and a general understanding of what I was about to experience.... I researched A LOT before I did it.

As long as you're in a safe place with cool people, I see no reason why an 1/8 would be bad for anyone.
