Just got peyote (pic)

Hi all, i just got some peyote, i'm planning on eating it with 4 more friends at a field. I was just wondering if this is enough for five people and if the root has any psycoactive effects?

Here's a couple of pics:

 

I think you would need at least 10 grams each, more or less depending on the potency.

 

You'll need more like 27g for each.

 

And about how much is that?
The whole thing weighed about 70 grams, but i don't think the root is useful.

 

That looks like lophophora diffusa, rather than williamsii. You might want to check out this link: http://erowid.org/plants/peyote/peyote_info2.shtml

 

Please Plant That Thing You Be better Off. That wont even get you High. If Worst Case plant the root. Dont fuck This up!

 

i live in boston, where peyote is never found. what are fair prices? and is it priced by gram or button? i remember the prices at the amsterdam smart shops were by button, and were well out of my price range... something like 20-30 euro per button= a few hundred for one dose.

 

oh and bluefrost is right. does not look like the williamsii ive seen.

 

and im pretty sure that lophophora williamsii only converts non pschoactive alkaloids into mescaline in the buttons. if you have full specimens, i would suggest looking up (i dont have the link) methods of cutting buttons that allow regrowth, and sewing the buttons into a san pedro. that way in a year youll have plenty for you and your friends.
