If you get 8 people, go in it together and buy an ounce! Then split it 8 ways.

If you get 4 people, go in it together and buy an ounce! Then split it 4 ways... and the real fun will begin.

Oh, and for shrooms, unless you're really big, which you aren't, weight has very little to do with dosage.

I'd say 1/8th is a good dosage for everyone there looking to get fucked up.

And 1/4th is a good dosage for everyone there looking to get REALLY fucked up.
