An opium lamp is an oil lamp designed specifically to facilitate the vaporization and inhalation of opium. Opium lamps differ from conventional lamps for lighting in that they are designed to channel an exact amount of heat upward through their funnel-shaped chimneys. An opium pipe, its pipe-bowl primed with a small dose of opium known as a "pill," was held over the opium lamp causing the opium to vaporize and allowing the smoker to inhale the vapors.[1]Opium lamps were crafted mainly in China before the communist revolution in 1949 brought opium smoking to an abrupt halt there. Small-scale production of opium lamps continued in Hong Kong and parts of Southeast Asia including Vietnam until the mid-1960s."
