Opium Museum
just opposite the golden Buddha at the very heart of the Golden Triangle
About
The hand-painted description and battered old display cases here pale in comparison to the multi-media extravaganza that is the Hall of Opium , but here you can find much of the same info about cultivation, distribution, and opium's place in global trade. There's lots of paraphernalia and a certain battered charm to the place (plus there's a good little souvenir shop and toilet stop for on the way to Chiang Saen).
