Popular slang for this drug of course includes crystal, but more commonly tina -- a corruption of the word sixteen, based on the concept of one sixteenth of an ounce. When you see Craigslist classified ads from people searching for a "party with Tina," you can rest assured they're willing to spend anywhere from three to five dollars.
