At one point, heroin came into the picture.

While paying off a debt to the aforementioned baddie U-Turn, Nancy was tasked with retrieving a package from Guillermo, head of the Tres Seis gang. Obtaining said package required her to perform the now-infamous ''brick dance,'' or a hoochie jig that'll earn a lass a block of heroin. Turns out he slipped her a bunch of weed instead, but Nancy will later dance (metaphorically) with Mr. Brownstone when U-Turn dumps a chest of smack in her garage for safe-keeping. It was then that Weeds became a little bit darker.
