According to tv.com, the overview is:
When Brian gets busted for possession of marijuana, he starts a campaign to legalize the drug. Mayor West passes the law, which turns the townspeople into a bunch of potheads.
I'm kinda worried about the last part, "which turns the townspeople into a bunch of potheads." I have a feeling they may show some negative light on potheads. Hope I'm wrong though and as a HUGE fan of Family Guy, I can't wait for this episode.
Well here are some examples of past pot humor from Seth

They aren't super negative..I predict the "potheads" will all be red eyed people with the munchies. Nothing stupid, like killing themselves.
