Well, I smoked some herb with a buddy one time that made me laugh my ass off for probably 3 hours straight. The next day the muscles on my stomach hurt from laughing so hard. I have no idea what that weed was called, if it even had a name.

My brother went to Oklahoma for a family reunion type thing just a few weeks ago and got a small amount of some free Trainwreck. I didn't get to smoke any of it with him before it was gone, but he said that it would turn people's eyes completely red before they got done exhaling their first hit.
