Distortion

[Magic]

I thought it be a good idea to have a dose that distorts your vision or sight. Not like a hallucination but the kind of sight when your slighty high or buzzed. Effects would be distortion of course, slight euphoria, hard to concentrate ect.. Something you can put your friend on and watch him walk a straight line

YouTube - Natural Hallucinogen
Watch the center of this for the full length it distorts your vision XP
I watched it for the full time and the effect lasted for a few minutes maybe XD

A few minutes a bit exaggerated, usually it lasts anywhere from 5 to 60 seconds, of course it feels longer when everything is "breathing". I don't think it could affect your eyes that much to leave the afterimage for several minutes, unless you look for a REALLY long time. But ya, that thing is cool.

The doses on here just distort vision, and do not cause hallucinations. So just do the hallucination ones, those distort.

Maybe a minute or something XD
I put my head quite close to my screen and stared at the center of a downloaded version of that video for 5 minutes+ i think XP
YouTube player reduces quality if the .flv it plays i think =P

I could just do it again and time it maybe XD
