Last night I commented on 420 and apparently none of you knew about it including one quasi hippie who was unfamiliar. First, it’s a fairly recent phenomenon in the last twenty years or so. Next it apparently came about because of high school students who got out of school at four and got together to light up at 4:20. Eventually 420 just became shorthand for weed

Now I also remembered how I knew about it. When I was on some dating sites more than ten years ago, some profiles contained the phrase 420 friendly which I looked up.
