`The Drug Enforcement Administration agents were near the Philip Burton Federal Building at 1:15 p.m. when a man passed them on the 400 block of Turk Street carrying a cardboard box. The box, emblazoned with the logo of a common brand of hydroponics equipment, reeked of marijuana. [..]

The narcotics agents stopped the man and asked what was in the box. He showed them about 1.5 pounds of marijuana, 12 ounces of hashish and an electronic scale.

Then, in a move that apparently stunned the 20-year-old Eureka resident, the agents took his pot away. While his crime was too minor to prosecute under federal law, the federal government does consider marijuana to be contraband, McEnry said. [..]

Realizing the DEA did not intend to return his stash, the man then called 911 on his cell phone to report the incident to San Francisco police.’
