The FDA made fools of themselves on 420 and this approval simply solidifies it.
I wonder if she has made the connection since then?
That they released the news on 4/20 seems to confirm their knowlege of 4/20. They are in a sense making fun of themselves and the cultural phenomenon (if you can call it that).
I don't think my aunt ever figured it out. She's hip to be square if you know what I mean. Her daughter, I think, enjoys a little too much recreation and my aunt is pretty liberal, but I don't think she ever took a drug that wasn't prescribed to her. In fact, I don't recall ever seeing her drink alcohol.
