If you grew up in the 70's that means you were a kid. Us kids weren't exactly old enough to be partaking of any of that "free love" you're all flapping about.
The 70's took me from grade 1 to grade 11. I graduated in '81. Smoked my first J in '82 come to think of it.
Good thing there was still a few good years of free love in the early 80's. :D
