The stuff we got back in the '70s was fairly mild. Pretty much regardless of how much you smoked, you just got mellow, thought everything was hysterical and got really hungry. You could still do stuff like drive (though in retrospect that probably wasn't a good idea). Ten or fifteen years later I shared a joint of something called Georgia Kickass with my brother-in-law - one joint - and literally forgot how my legs worked. I mean I didn't just forget how to walk, I forgot how to stand up.
