Indian tribe where everyone smokes as past time

In this Indian Tribe, everyone smokes as past time, including the village chief. Many sell their properties just to fund the old habit of smoking opium. Sitting on the dangerous Myanmar border is an Indian village of head-hunters with an opium addiction so pervasive a third of the population smoke the drug with many having to sell their possessions to fund the habit and 90% have used the substance.

What are the authorities doing about it you ask? Well, the village chief Tonye Phawang and his caretakers spend all day smoking opium.
 

While the Indian government is taking steps to eradicate the problem, opium is readily available through Myanmar - the second largest opium producer in the world.
 

Opium is a highly addictive narcotic drug acquired in the dried latex form from the opium poppy (Papaver somniferum) seed pod. ... Heroin (diacetylmorphine) is derived from the morphine alkaloid found in opiumand is roughly 2-3 times more potent. A highly addictive drug.
