So, I've got a quick travel tip for you.
It's probably not a very good idea to light up a joint on a commercial flight. According to TMZ, an American Airlines flight from Arizona to Minnesota was forced to make an emergency landing on Friday when a man allegedly sparked up a join the plane's bathroom. He looked himself inside the bathroom and the captain announced that their was "a security issue in the back". The captain decided to divert the plan and land in Denver (which is a little bit ironic, don't you think?).
See the video from TMZ below.
