Pretty sure this topic has been discussed before...

I've tried it like twice. The first time sticks out in my mind the most. Me and 3 of my friends smoked about two bowls out of a bong. As soon as I hit it, I was lit. We all started cracking up. I found a pencil that I swear was made out of rubber. It amused me for like 5 minutes. I donno, I was really fucked up. But it only lasted about ~10 minutes, but it was extremely intense.

Eh, it's legal, it's trippy... go for it.
