Fergie Said She Hallucinated Everyday When She Was Addicted to Crystal Meth Before her rise to fame as a member of the Black Eyed Peas Fergie was addicted to crystal meth in the early 2000's. "At my lowest point, I was [suffering from] chemically induced psychosis and dementia." "I was hallucinating on a daily basis. It took a year after getting off that drug for the chemicals in my brain to settle so that I stopped seeing things. I'd just be sitting there, seeing a random bee or bunny." Fergie also went on to say that her faith and hope for something better was what helped her get over her addiction.
