Ehh, I only wanted to do it once because a friend of mine was saying it messed him up. I know it kills many of brain cells, along with most all inhalants. I usually do stick to the pot or shrooms. Every now and again I'll do acid. But, Acid is like maybe 1 or 2 times a year, I don't want holes in my brain. I mean, I'lve already messed my head up with I went on a binge of dramamine when I was 14, now my walls are constantly shifting and it's horrible. Haven't touched the stuff since. Wow, Sorry for rambling like that.
