There was a long thread on this on the alt.folklore.urban newsgroup within
the past 6 months to a year. I wasn't paying serious attention to it, but
recall some speculation about police radio codes.

Ah...Deja-news came up with the start of that thread; another thread that
came up when I searched with keywords "4:20 pot" came up with a marvellous
just-so story from April 1999 involving mad scientists measuring rate of
THC uptake, an unnamed university in California, and a digital clock.
