I once volunteered to eat an entire bud brownie which is quite potent for someone who's never eaten one before. I was hungry.
I went on a weird trip. It's like a body high almost like you're on vitamin E. Definitely not the same sensation as smoking it. It was fantastic though although initially my stomach was a lil upset. After 30 minutes or so it takes over and last awhile...several hours for me. To make it you need to cook the hash oil. That's the main ingredient I believe.
My advice eat a quarter at a time...hehe.
