In Rajasthan when you go to someone's house for a visit the first thing you're offered is opium in the form of tea. This woman took a chunk of the stuff (looks somewhat like hashish), ground it up and mixed it with water. She then filtered that through cotton sacks into wooden mugs. She poured some of the dark liquid into our cupped hands and we drank it down - a faint herbal taste.

Opium is a controlled substance in India but nobody seems to mind this ancient, homegrown custom. By the way, I didn't feel the slightest buzz.
