Just like the oregano vs pot scam. I've never seen pot, I have no idea if it looks like oregano or not. I've read that it does, but I don't know by my own experience.

Most PD's around the nation have educational programs to inform parents, teachers, and students regarding pot. Often they have examples. Perhaps as an alleged teacher you should consider learning about the subject matter before you make comments.
