Roseanne was cancelled recently by ABC Entertainment after a controversial series of tweets.
But the show's star tried to blame her behavior on a drug.
According to Roseanne Barr, her derogatory joke about former Obama adviser Valerie Jarrett was an Ambien-influenced rant.
But the maker of Ambien quickly responded to Barr's excuse.
Although Ambien has known side effects, racism is not one of them.
