ok mexico is all about getting the weed across the borders into the states
and questions the then goverment,s (nixon) anti drug laws and i guess the song still does that with current united states goverment. drug laws.
quite simply put the song is a rallying call to free the weed
and to put an end to inprisonment for those boys and girls who use.
the refrence to richard is about richard nixon an old president
i think he got caught out telling lies.
and mr owsley i belive he may have been a chemist of sorts
