mesc as far as I no isnt that common unless your a indian in that church thing. If you wanna trip off mesc then just buy a san pedro cactus and eat it. They dont taste that bad although by the time I was done my 14 inch cuttin I was ready to puke:/ If you live in Canada then you should buy a peyote instead. I dont think many stores carry those kind of cactuses but you can buy live cuttings off the net.
