The Internet is up in smoke in anticipation of 4/20.
Practically a national holiday for college kids and aging hippies alike, 4/20 celebrates the consumption of cannabis, Mary Jane, pot, whatever you like to call it.
According to
, the holiday got its origins in 1971 from a group of teenagers in San Rafael, Calif., who liked to meet up at 4:20 p.m. to get high. As a result, 4/20 became their secret code word and 40 years later, the code word for an entire nation.
