Please help with identification!

Hello guys,
i am sorry i pubish it here but i saw in this forum people have experience with some plant materials :) I got a cactus which i think is San Pedro but i am not sure. It has 5 ribs and 4 brown pins per areole. I attached and a picture if this can help. I have no big experience with cacti. I checked Erowid and other sites and Wiki of course. They say it has 5-7 ribs and 4-10 pins. The only thing which is bothering me now is the placements of the areoles.

If somebody can identify it please tell me.
Thanx

Sorry about your problem, but how's that in any way related to this board?

I guess because its a hallucenogenic substance it COULD be put here... kinda stretches the purpose of this forum =P

sorry but that doesnt look like a pedro to me. looks like it ould be a peruvian torch, (which has more mescaline in it then pedro) but it has visible spikes which pedro doesnt. idk if this is ok to post on this website, (if it isnt mods remove it) post on http://www.shroomery.org and they'll help you
