Well, I think its good that you chose to never do it again. Pot really messes with a persons mind. A lot of people says it makes them feel better, but it makes the people around them think differently about that person.
I have never tried it. I probably never will either.
I would like to add, however, that there could be legitimate medical reasons to smoke it. Some cancer patients use it to relieve the pain and reduce the nausea caused by chemotherapy. It also relieves eye pressure caused by glaucoma or similar diseases. This is a far different story than what you are talking about, but I just wanted to share my opinion.
