I've always taken the institutional teachings with a grain of salt and pinch of herb. I call it mindscaping...sadly...or perhaps not as I really don't know you, but look what happened with you. You're not alone. It really can be a hilarious experience when you first partake. If you're lucky things will mellow out to just the euphoric presence that you take it for.
Of course there is other reasons for it's use but I think the main thing is that, for so many, it frees the mind and boosts appetite. Myself I rarely have the munchies...the thought of stuff in my mouth is just kinda yucky.
Do be careful of the so called wheelchair pot. This stuff is so potent, and prevalent, today that you really shouldn't be needing to go anywhere for a couple/few hours after partaking.
Now it's time for you to listen to Ozzy's Sweetleaf
