Okay, so I found this site that tests your reaction time based on a color-changing background. I was doing it for awhile before dinner, and then when I was done with dinner and was getting ready to smoke I decided to test how my reaction time changed once I was stoned.
So. Sober, my reaction time, averaged over 15 trials, was .421 seconds (I was so angry I wasn't one-one thousandth of a second faster). Stoned, my reaction time, averaged over 15 trials, was .384 seconds. (I am an engineer, and I have terrible OCD, so everything I do is scientific and orderly.)
I have actually noticed this before, that my reaction time is better high. Quite a few objects have been thrown at me (mainly phones) that I really shouldn't have been able to catch, but I can catch them easily when high.
Anyone else have a better reaction time stoned then sober?
Oh, and the site is here: The Reflex Tester
