I did the same thing, my teacher knew i smoked mad amounts of weed though. I joked about it with her all the time. She was mad cool, like 24-25 years old, and she was fuckin mint lol The assignment was to write a letter to the PM(Paul Martin lol) I wrote about fully legalizing marijuana, and selling it in stores lol And we actually sent it to the PM... They can't say shit, just because oyu wrote about it doesn't mean you do it, it may just be an issue that concerns you..
