I lived in Barrie in the 70's and our house was on a corner lot. All the kids going to school used to stop off at our house on the way to school and smoke up. In throught the front door, and our through the back.
My first few years of high school were hell because I didn't know anybody but suddenly in the last year, I got into a band and our house became the weigh station on the way to school for everybody.

I'd say my best years and most memorable experiences were a result of making friends who smoked up. We used to go out of our way to find adventures just so we'd have something to do while we were smoking.
It was like "hey we've got pot.... lets go downtown and play pool, lets go swimming, let's go take off and find something to do... all for the sake of the fact that we had pot.

About the only thing harder that we ever tried was hash oil or hash.
We dabbled in mushrooms and peyote but could never find the stuff so only tried it once or twice. I think we tried acid a couple of times but that was it.
(the funniest drug in the world... like seriously you can't stop laughing).
Mostly though it was plain old pot and even then it only when we could get it. It wasn't like we had it all the time.
One thing I remember is we never drank alcohol except very occasionally at parties.

Anyways... I guess the point is, back then, it was part of the culture.
Nobody thought twice about doing drugs and it was the thing that made life interesting. Even my best friends mom smoked up and provided us with pot.
It was just a way of life and no more illegal or shocking that*drinking beer.

All the freak out crap these days is propoganda by the government and cops who want to make their daily quota of arrests and advertisements that they're doing something to combat the problem.
