It must have been laced with something!
smoking the herb every couple of weeks seems to be the way to go. I smoked daily for about 10 years and have recently managed to cut back to about every couple of weeks or more and as Allusion said, now I know why I loved it so much in the first place (I'm also saving heaps of cash by not buying anywhere near as much).
I hope you enjoy this place, I've only been here a little while but I love it. There's some really great people who post on here.
