So, yeah, how much money will it cost for enough substance to ruin your life forever? That would be not very much. Of course, you WILL like it, and it will take you over, and eventually you'll be spending more than I make in a year just to keep yourself from getting sick. Once is too much, Mike. Whether it's for you or a gift for a friend, or whether you're just trying to figure out how deep your friend is in, the answer is the same. Run, don't walk -- run screaming. You have NO clue.
