Awkward conversations. They’re the heart of the drug trade. The driving force that keeps criminals out of jail is paranoia. You can think you know people, but the truth is, you never know who they’re talking to. The life of an outlaw: Around every corner lies a cop. In every basement waits a bust. Every friend is the guy who sells you out to keep his own ass out of jail. Sure, it was rare, but you just never knew.The result was a series of shorthand and euphemisms so obscure even the pros often weren’t sure what they were talking about. Sales became pickups. Pot, ganja, bud, or weed became lettuce, green, happy, herb, smoke... the list went on, and changed from dealer to dealer.
