Lapham's Quarterly lists some classic works of literature and the substances that fueled them.
Folks aren't into laudanum the way they used to be. The name has a nice, ruined-gentility ring to it--as do its alternative names, opium tincture and thebaic tincture. I can't think of the last time I had a tincture of anything. It would have to be ingested while wearing lace cuffs and reclining on a fainting couch...which, come to think of it, does not preclude writing on a laptop.
