House of Opium

Lonely Planet review

This small museum with historical displays pertaining to opium culture is worth a peek. Exhibits include all the various implements used in the planting, harvest, use and trade of the Papaver somniferum resin, including pipes, weights, scales and so on, plus photos and maps with labels in English. The museum is at the southeastern end of Sop Ruak, virtually across from Phra Chiang Saen Si Phaendin.
