white lightning

   1. LSD

   From its effect on those who ingest it:

    Ellen... unfolded some tinfoil which she said contained three tabs of Owsley's original 'white lightning', the Mouton-Rothschild of LSD. {Village Voice, 1 June 1972)

   2. a spirituous intoxicant

   Either illegally distilled, and uncoloured, whisky, or standard gin or vodka. Also as white eye, mule (from the kick), satin, or stuff: ... 'white lightning', 'white mule', or just plain 'corn', as the local moonshine whiskey is called. (Double Dealer, July 1921)

    White satin, if I must know, was gin. (Mayhew, 1862)

    He was drunk... He'd been on the white stuff all day long and was drinking it like water, (le Carré, 1989)
