There's no brickweed in Canada, but there is shagg, at least I had it before.

My buddy used to work in the pipeline way up North in Alberta, Canada. The only weed he could get out there was this rock hard bud, loaded with seeds. He brought back an ounce with him, told me to roll one up, and there wwere pieces of corn husks in with the stuff. I guess this shit was grown in a cornfield. It was by far the worst stuff I had ever smoked.

You opened up a bud, and seeds would pour out. I had to use like 4 grams to roll up a cigg. sized joint, and after 2 more of them, I was ready to puke. I even said "I was good." I never say that!

So it is around. It's rare, but that scary, horrible stuff is out there.
