Dope is related to hops (methinks) and has been used in beer to enhance it. I remember a friend of mine who's a scooper, ie someone who travels around trying rare and unusual beers, fetching up in a large-ish town to try a rare and unusually powerful beer that was brewed on the premises of the pub.

As he slowly sipped his way down the bber, the pub gradually emptied of the lunchtime trade until he was the only customer left. So he duly got chatting to the barman about his reasons for being there, at which he was asked whether he wanted to try the "special" barrel of the beer he was drinking that had had a large amount of "herb" added for a party.

It's the only instance I know where I could actually tell you which pub and which beer, but I'm sure there have been many others
