From the files of "Where'd that law come from?" we turn to Section 11352.1b of the California Health and Safety Code, which makes it illegal to sell "any material represented as, or presented in lieu of, any dangerous drug or dangerous device."

The story behind the legislation takes us to a Chinatown street in the early 1950s where two undercover police from the narcotics division were attempting to score marijuana, and arranged a "hand-to-hand go" of $300 for 5 pounds of "manicured tea."  They had their street lingo down, but I'm sure you can see where this is going.  The dealer took their money, and proceeded to hand over exactly what he'd promised -- 5 pounds of tea.  At those prices, let's hope he at least sprung for Twinings.

Once the crime lab revealed their folly, the two officers rushed back to Chinatown to arrest the enterprising young dealer until realizing that they didn't know what to arrest him for.  Finally, they settled on the somewhat dubious charge of grand theft.
