The story I was told when I managed the dodgy but interesting campus radio station here at Brock, is that "420" was the LAPD "code" for posession. It was (so I was informed) coopted by the potheads--nothing like appropriation of official language to subvert authority, I figure. One of our programs "The Bong Brothers" (no kidding) would, at 4:20, drop the volume of the music, announce cryptically: "420", and then turn the particular Grateful Dead or Phish tune they were playing back up. As I was the manager and not a pot smoker, they were disappointed that I didn't let them proceed to light up.
